EDITOR’SNOTES ‘No Longer Just a Reprogramming Standard’ J-2534 Discussed at Spring NASTF Meeting “The topic of J-2534 and pass-thru programming has been the single-most dominant question that I have had to deal with at NASTF,” said Skip Potter, executive director. Because of this, the group organized a panel discussion for its Spring General Meeting in Seattle March 20.

“This involves the technicians, the OEMs and the tool makers,” Potter said, so the panel was set up with representatives from all three: Bob Augustine from Christian Brothers Automotive, Mark Saxonburg from Toyota Motor Sales USA and Brian Herron from Drew Technologies.

In discussing the evolution of the J-2534 standard, Augustine noted that “the aftermarket was really green in terms of figuring out where they wanted to go with it.”

Herron said, it’s no longer just a reprogramming standard. “There’s been a lot of pain along the way, a lot of learning, but it’s really a strong foundation going forward that we can all utilize for more diagnostic capabilities.”

Potter commented that when the J-device first came on the market, technicians saw it as an opportunity, particularly if they worked on more than one make.

But not all OEMs are putting the same resources into the pass-thru device.

“Some companies looked at this (the standard) as a regulatory requirement,” Saxonburg said. “(Toyota) looked at it as an opportunity to leverage this recommended practice as a way to better support our customers, both in the dealership and outside of the dealership, by giving them a less expensive way to do all of our diagnostics.”

Augustine noted that the big challenge right now for the average three- or four-bay, family-owned shop is that it is cost-prohibitive for them to buy multiple OEM factory scan tools. Most people following the J-2534 discussion were thinking they’d be able to by one box (J-device) and work on every car, he said. “There really is tool hardware fatigue in the aftermarket.” Techs are looking for one tool that can work on at least the big six or seven brands they work on. “At the end of the day, I think our challenge is, can we make that happen?”

Education and formal training seem to be the main disconnect in proper use of re-programming tools.

“You can’t just plug in a reprogramming tool and

4 April/May 2014 | TechShop

push the green button and expect that it’s going to have the desired result,” Augustine said. “It takes some research (checking TSBs first, for instance) and sometimes it takes some actual field experience to know what the right thing to do is.”

He continued, saying that adequate training is not going to come from a local parts house. “J-2534 is one of the topics where you’re not going to ... be able to do something with it successfully without some real formal training ... or the learning curve is steep and expensive.”

In addition to training, Saxonburg said it is among the technician’s responsibilities to be what he calls “Service Ready” — be educated on the task you’re about to perform. He suggests techs research unfamiliar cars before attempting to repair them. “All reflash events are driven by a TSB of some sort.” First ask yourself, “What am I trying to fix with this re-flash? How do I do it, and what are the things I need to look out for?”

“The number one responsibility (of the technician) is to not practice on customers’ cars,” Herron said. He recommends techs take the time to read the vehicle maker’s requirements and find out what version of operating software and PC you should have (also, keep a clean, virus-free system for reprogramming). Are you using a validated device? Are there any other equipment requirements (adequate battery charger)? Know where to go to get support, such as the OE, the toolmaker, NASTF’s website or a forum such as iATN. And he advises that it’s important to follow the TSB procedures. “(These steps) are key to minimizing the issues that come up through that process.”

Wrapping up the session, Potter said NASTF will continue to help in resolving some of the problems the standard presents.

New Multi-Speed Tire Changer Introduced

Heavy Duty-Ratchet with 17-Tooth Pawl The Beta Tools of Italy 920/55 Reversible Ratchet is not your ordinary 1/2” drive ratchet. Instead of using a double-pawl inside, Beta Tools uses a solid, one-piece pawl with 17 teeth on it. This is unique not only because this is more total teeth than most ratchets, but also because the design allows all 17 teeth to be engaged at one time through the tightening or loosening operation. This ratchet has 72 teeth, but Beta Tools also offers a 48-tooth option that has an 11-tooth pawl. The 72-tooth model only requires a 5° angle of operation. The Beta Tools Reversible Ratchet is available in 1/4”, 3/8”, 1/2” and 3/4” drive sizes. The 1/4” is only available in 48-teeth and the 3/4” is only available in 72-teeth, but the 3/8” and 1/2” are available in both 48-teeth and 72-teeth versions.

MAXIMIZING TOOLS

In a previous article, we examined the use of unconventional but simple methods for detecting electrical faults in vehicles. We discussed digital multimeters, current clamp meters and a digital oscilloscope. In this article, we will similarly discuss an alternative approach to diagnosing an engine using the pressure waveforms from an in-cylinder pressure transducer.

We are going to diagnose engines based on the pressure waveform obtained from the cylinder(s) of a running engine. We will need to safely disable the ignition for the chosen cylinder. One method is to connect the coil or plug wire to a spark tester. To avoid any problems from ignited fuel, from perhaps a hot surface in the cylinder, we should disable fuel delivery to the cylinder being tested as well. To display the waveform, we use a transducer that converts pressure into voltage. The voltage output can then be displayed as a trace on an oscillosocpe screen. The transducer is replacing the spark plug in the cylinder being tested. (See Photo 1.) Due to heating of the transducer from the running engine, the test should not run more than approximately three minutes. If the spark plug is recessed, it may be necessary to use an extension,

as shown in Photo 2, called a deep well adapter. A flexible extension, such as from a compression gauge set, should not be used. This is because the flexing may cause a loss of detail in the waveform.

Although the transducer shown here is incorporated in the oscilloscope kit used, other transducers can be used as well. The pressure transducers used should have low inertia, so they react quickly to pressure changes. They should also be accurate, retain accuracy as they warm up, and accept as well as recover quickly from pressure overload situations.

Reading and Diagnosing the Pressure Waveform After setting up the transducer and the oscilloscope, a waveform (Figures 1 and 2 or similar) will

MAXIMIZING TOOLS be obtained once the engine is started. It’s best to save and/or record the waveform, then analyze it. This way, there are no time limitations present with regards to running the engine.

It may take some time to become comfortable with using these waveforms to analyze engines. The particular software shown here has provisions for performing autoFigure 1: Recorded pressure waveform from a matic analysis, which can be very cylinder of an engine in good condition. helpful, especially when you’re starting out performing this type of diagnosis.

Automatic Analysis of Anomalies in the Pressure Waveform In Figure 3, the software has automatically detected deviations from the positions of characteristic points in the graph as well as shape distortions. Due to this automatic capability, the probability of detecting a mechanical defect in the engine increases, and the time spent on waveform research is significantly reduced.

The Report Tab

Advanced Automatic Analysis Transcribing the Waveform This particular software automatically analyzes the cylinder pressure waveform and generates a print out or report with a number of additional parameters and characteristics of the engine and the associated control unit. The calculated values are pneumatic and geometric characteristics of the cylinder; the list of found deviations is displayed in the form of text messages. To improve speed and accuracy of valve timing research, the cylinder pressure waveform is converted into a diagram of the gas amount in the cylinder and is displayed in two different ways, using a script.

filling of the cylinder during the intake stroke, which characterizes the properties of the entire intake manifold of the engine is also provided. A diagram showing the energy consumption for scavenging exhaust gases from the cylinder is provided as well. Using these diagrams and the igntion timing signal, the ignition timing diagram is built and can be displayed.

Naturally, the script cannot replace an expert diagnostician, it can only convert cylinder pressure waveforms into a more readable form, but it does allow for a decrease in the time a diagnostician spends on analysis, and also to limit missed implicit/hidden deviations/faults. For more detailed information on the possibilities of the script, we will review each of its report tabs.

Figure 3: Deviations in the cylinder pressure waveform automatically detected and displayed by the oscilloscope program.

Figure 4: The report tab from the Px script.

The conventional or classic tool for assessing the state of an engine cylinder and piston is a compression gauge. It is designed to measure the compression or peak pressure in the cylinder obtained while cranking the engine. The measurement is a complex value and depends on losses through cylinder leakage, the compression ratio, the valve timing, the cranking speed, and the state of the intake and exhaust ports or manifold.

A reduction of compression pressure in a cylinder is usually thought of as being caused by cylinder leakage or valve timing.

However, the reason can also be reduced geometric compression ratio from, for example, a bent piston rod, due to hydrolock. Hydrolock occurs when a piston tries to compress something non-compressible, such as a liquid.

The Px script, as shown in

Circle #11 for Reader Service

8-14 Maximizing Tools 4/2/14 9:00 AM Page 12

MAXIMIZING TOOLS Figure 4 on page 10, can distinguish cylinder leakage from low compression ratio because it independently calculates gas losses and the compression value.

The compression ratio can usually be found in the service information, under general engine data, and depends on the engine’s design.

Normal pressure or gas loss for an engine in good condition is in the 10-18% range. A loss of more than 20% could indicate excessive leakage in a cylinder.

The algorithm for calculating cylinder losses is com-

Figure 6: This is the characteristic shape of the left part of the red and green traces from an engine in good condition.

plex, with some variables that are difficult to account for. A typical problem is the heat loss of the gas in the cylinder.

The heat loss arises from the fact that the gas temperature in the cylinder during compression, even without ignition, is rising above the temperature of the cylinder walls. Consequently, part of the heat energy of the gas in the cylinder is transferred to the piston, cylinder and cylinder head.

The loss of heat causes a loss of pressure. In practice, the calculated cylinder pressure loss of an engine in good condition is about 10%.

Figure 5: The quantity tab from the Px script report, this engine is in good condition. The graph indicates the amount of gas in the cylinder relative to the position of the piston in the cylinder and the stroke. Marker A is set to coincide with the end of the intake valve closing and the opening of the exhaust valve beginning.

The Quantity Tab Figure 5 shows a diagram of gas in the cylinder depending on the piston position and the stroke.

Figure 6 is zoomed in on a portion of the graph from Figure 5 and shows the typical shape of the graph from an engine in good condition.

For the following few paragraphs, please refer to Figure 5. When plotting a diagram of the amount of gas in the cylinder, four colors are used that reflect the working strokes. The piston is at TDC on the left side of the diagram and at BDC on the right side. The volume of gas in the cylinder is represented by how high the trace rises in the vertical direction.

As the piston moves farther away from TDC on the intake stroke, given as the green trace on the diagram, read from left to right, the volume in the cylinder is increased, the pressure is lowered, and so ambient air flows from the intake manifold and into the cylinder.

This causes the green trace to rise.

At BDC, the piston changes direction and the volume in the cylinder begins to decrease, but the amount of gas in the cylinder continues to increase as evidenced by the blue trace on the diagram in Figure 5. The increase in gas volume occurs because the gas has weight and thus has inertia, causing the flow to continue even after the piston has changed direction on Circle #12 for Reader Service

12 April/May 2014 | TechShop

8-14 Maximizing Tools 4/2/14 9:01 AM Page 13

BDC. After the gas flow has stopped, gas may start to flow back into the intake manifold due to the piston action. This backflow depends on the timing of the intake valve. When the intake valve is closed, no flow will exist, and the blue trace becomes essentially flat.

In this particular case, the filling of the cylinder is maximized at 155° before TDC, and the intake valve closed approximately 140° before TDC. After the piston passes TDC, previously compressed gas in the cylinder begins to “decompress,” but since the valves are closed, the amount in the cylinder is still almost unchanged, so the graph looks almost like a straight line (yellow trace of the diagram, the left side, read from left to right).

However, the clearly visible gradual spread between the straight yellow diagram trace and the blue trace indicates the quantitative heat loss of the gas in the cylinder. The greatest amount of loss is observed near TDC when the gas pressure and temperature are at their maximum.

The exhaust valve begins to open before the piston reaches BDC. In this particular case, the opening starts at 140° after TDC. The pressure measurements are made without a source of ignition, so there’s no combustion. The cylinder pressure at this point is almost identical to the pressure in the intake manifold, which is well below atmospheric pressure. The pressure in the exhaust manifold is close to the atmospheric pressure and exceeds the pressure in the cylinder. Therefore, once the exhaust valve starts to open, the exhaust gases from the exhaust manifold begin to flow into the cylinder. This flow equalizes the pressure in the cylinder with the atmospheric pressure. This equalization is reflected in the

Further, because the volume in the cylinder is When approaching TDC, the exhaust valve begins to increasing, the gas flows from the intake manifold close and the intake starts to open. At this point, the again. pressure in the cylinder is still close to atmospheric, Thus, using the graph of the gas quantity in the cylinder we can detect and measure where the intake valve closes and where the exhaust valve opens. If the nominal values for valve opening and closing are not given, deviations will have to be detected based on cylinder-to-cylinder variation (or comparing to a known-good engine).

Different manifold designs will show different relative timing with respect to intake and exhaust phases.

However, the width of the intake phase is always substantially the same as the exhaust phase. The phases are always substantially symmetrical relative to TDC as well. In practice this means that when the intake valve closes at 140° before TDC, the exhaust valve must be opened approximately the same 140° after TDC. In other words, in the same relative position of the piston. Because of this symmetry, the diagram of the amount of gas in the cylinder shows the same characteristic points located above one another. This is true for engines with narrow valve timing and with wide valve timing — phase asymmetry usually does not go beyond ±10°. This rule does not necessarily apply to engines equipped with variable valve timing, however.

Figure 7 shows the result if the timing belt or chain is installed one tooth late on an engine with a single overhead camshaft. This error generally causes about a 15° delay. In Figure 7, the amount of gas in the cylinder is reflected as an offset of the closing of the intake valve at about 15° to the left, and the opening of the intake is about 15° to the right. In this case, it turns out that the characteristic points are away from each other by approximately 30°. TS Circle #14 for Reader Service

his article will document the infamous P0340 code — Camshaft Position Sensor Circuit Malfunction. This is a code that involves the CMP signal, and, in many situations, one may be tempted to replace the sensor right away. This article will attempt to provide a game plan of attack.

It’s always wise to start with a schematic of the system you are working on. See Figure 1.

Our subject vehicle is a 1999 Ford Windstar. The camshaft signal on this vehicle is used per the PCM to control injector timing. This vehicle has a rough cold start, but does start immediately. It appears to have multiple cylinders that are misfiring.

Our first step is to verify the complaint by checking the system with the EASE software, a PC-based system. It confirms we have a P0340 stored in memory. Let’s review the

freeze-frame data and misfire data.

See Figure 2.

COMPRESSORS

N

othing is more frustrating than hitting the trigger on an air tool and a stream of water comes out the exhaust port. But, where did it come from? What can be done to prevent it from getting to your tools?

Water is all around us. It is in the form of vapor mixed with collection of gases we breathe. How much water is in the air is dependent on temperature and how much is present in the environment.

And while you can’t control the weather at your shop, you can control the quality of the air coming out of the compressed air lines with a couple of compressor strategies.

Temperature The amount of water held in air is dictated by temperature. It is simple physics that hot air can hold more water (as vapor) than cold air. At higher temperatures, water molecules are more likely

to go into the vapor phase, so there will be more water vapor in the air.

When the air cools down, the water has to go somewhere. If you were to graph temperature against humidity, where the two lines cross would be called the dew point. At this point the air becomes saturated and the water condenses into droplets. Dew points can occur at 200° or 32°, depending on relative humidity and temperature.

In the case of a shop’s air compressor, the air in the compressor room maybe as high as 130° and the air coming out of the lines in the shop maybe 80°. During this drop in temperature, chances are a dew point will be crossed. When this happens, water droplets form in the compressor or the lines.

Solutions You can’t shut down your shop on a humid day, nor can you afford down time due to malfunctioning air tools. You can help to eliminate problems by controlling the temperature of the air going into and out of the compressor.

Look at where your compressor breathes. If

COMPRESSORS your compressor can’t pull in cool and dry air, it is already handicapped. If your compressor is in a small room that receives inadequate ventilation, it can increase intake temperatures and the amount of water in the intake air. A little ventilation from an exhaust fan can go a long way to lower temperatures and water.

Most professional-level compressors use the strategy on lowering air temperatures on the output side of the compressor. This has been traditionally done with finned lines from the compressor to the tank.

The goal is to cool the air enough so water condenses in the tank.

In theory, no water droplets would make it to the tools. It works if the temperature drop from the tank to the tool is not great enough to cause the dew point to be reached. But, with longer airlines, it is possible to get enough of a temperature drop to get condensation.

Some new compressors have refrigeration units that cool the compressed air and draw out the moisture so the dew point is the

same from the compressor to tool. These coolers or dryers can chill the air to an adequate dew point so the water stays in the compressor room and out of the lines. While refrigerated compressors can be more expensive, they can eliminate down time and water in the lines. TS

What About Water Separators?

Water separators should be located as close to the air tool as possible and before any pressure regulator. A separator uses centrifugal force to remove water droplets from the air. Air is spun around the chamber and the rotational forces propel condensate droplets toward the separator wall from where they flow into the collection chamber. Units should be drained at the end of the day to prevent water from making its way to your tools.

COMPRESSORS

Consider The Costs Planning on buying a rotary screw compressor for your shop? Not so fast. Although the convenience of constant air supply sounds appealing, don’t rule out traditional reciprocating piston compressors as an option. Be sure to consider all the upfront and long-term costs before choosing between the two types.

Purchase Price Piston compressors have a much simpler design than rotary compressors and, as a result, have a much lower purchase price. The additional components of rotary compressors, such as liquid cooling systems and air/oil separators, add a lot to the cost.

Energy Usage One advantage of piston compressors is that they only use electricity when they’re compressing air. On the contrary, rotary compressors are designed to run continuously, even when they’re not compressing air.

Granted, some rotary compressors automatically go into standby mode after idling for five or 10 minutes; nonetheless, that’s still five or 10 minutes of wasted energy, which can significantly impact the electric bill.

Maintenance Rotary compressors generally require specialized lubricants, which, in some cases, may cost several hundred dollars for a five-gallon bucket. It’s possible for a rotary compressor to rake up a $500 service bill every three to six months. In fact, total service costs can surpass the initial purchase price after only five years of use.

Overall, maintenance on a piston compressor is simpler. As long as the operator regularly changes the air filter and pump oil, the compressor is likely to provide years of trouble-free service. Furthermore, the oil for a reciprocating piston pump is much cheaper, and the quantity is less.

TOOL TIPS with the following concerns and report. The customer drove the vehicle about 1/4 mile before it shut off the last time. If the engine was left running, the A/C stayed off. If the engine was shut off and then restarted, the A/C would start working again, losing ground for the A/C relay. The tech went through the self-diagnosis of the automatic A/C system and it gets a 20 (no malfunction detected). The ambient sensor, the in-vehicle sensor and the intake sensor all read normal temperatures. The scan tool does not show A/C request or A/C relay information. The scan tool shows engine temperature at 190째 F. The A/C compressor rpm sensor was replaced, but that did not help.

Potential Causes: A/C compressor revolution sensor wiring Tests/Procedures: 1. Backprobe and check the A/C request circuit voltage on the black/white wire in terminal A2 (terminal 2 of connector A, which is connector B134) at the engine control module (ECM). Look for battery voltage to be present from the auto A/C control module for A/C

request to be on.

2. If the A/C request voltage goes to 0 volts when the A/C compressor shuts off, perform voltage tests at the auto A/C control module.

3. If the A/C request voltage stays at battery voltage when the A/C compressor shuts off, backprobe and check the ground for the A/C relay on the blue/orange wire in terminal D27 (terminal 27 of connector D, which is connector B137). If the A/C relay ground goes to battery voltage (no ground), then ground the blue/orange wire at D27 and verify the A/C relay and the compressor clutch turns back on.

4. Scope the A/C compressor rpm sensor on the white wire at terminal A13 (terminal 13 of connector A) at the ECM and look for a clean, consistent AC sine wave signal with the engine running and the A/C compressor clutch on.

5. Make sure the ground for the A/C compressor rpm sensor is good on the black wire.

6. Check ECM grounds as necessary.
