HOW TO USE THIS MANUAL Description

INFOID:0000000001342940

This volume explains “Removal, Disassembly, Installation, Inspection and Adjustment” and “Trouble Diagnoses”.

Terms

INFOID:0000000001342941

• The captions WARNING and CAUTION warn you of steps that must be followed to prevent personal injury and/or damage to some part of the vehicle. WARNING indicates the possibility of personal injury if instructions are not followed. CAUTION indicates the possibility of component damage if instructions are not followed. BOLD TYPED STATEMENTS except WARNING and CAUTION give you helpful information. Standard value: Tolerance at inspection and adjustment. Limit value: The maximum or minimum limit value that should not be exceeded at inspection and adjustment.

Units

INFOID:0000000001342942

• The UNITS given in this manual are primarily expressed as the SI UNIT (International System of Unit), and alternatively expressed in the metric system and in the yard/pound system. Also with regard to tightening torque of bolts and nuts, there are descriptions both about range and about the standard tightening torque.

“Example” Range I

Outer Socket Lock Nut

: 59 - 78 N·m (6.0 - 8.0 kg-m, 43 - 58 ft-lb) J

Standard Drive Shaft Installation Bolt

: 44.3 N·m (4.5 kg-m, 33 ft-lb) K

Contents

INFOID:0000000001342943

• ALPHABETICAL INDEX is provided at the end of this manual so that you can rapidly find the item and page you are searching for. • A QUICK REFERENCE INDEX, a black tab (e.g. ) is provided on the first page. You can quickly find the first page of each section by matching it to the section's black tab. • THE CONTENTS are listed on the first page of each section. • THE TITLE is indicated on the upper portion of each page and shows the part or system. • THE PAGE NUMBER of each section consists of two or three letters which designate the particular section and a number (e.g. “BR-5”). • THE SMALL ILLUSTRATIONS show the important steps such as inspection, use of special tools, knacks of work and hidden or tricky steps which are not shown in the previous large illustrations. Assembly, inspection and adjustment procedures for the complicated units such as the automatic transaxle or transmission, etc. are presented in a step-by-step format where necessary.

HOW TO FOLLOW TROUBLE DIAGNOSES Description

INFOID:0000000001342946

NOTICE: Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following instructions before diagnosing. • Before performing trouble diagnoses, read the “Work Flow” in each section. • After repairs, re-check that the problem has been completely eliminated. • Refer to Component Parts and Harness Connector Location for the Systems described in each section for identification/location of components and harness connectors. • When checking circuit continuity, ignition switch should be OFF. • Refer to the Circuit Diagram for quick pinpoint check. If you need to check circuit continuity between harness connectors in more detail, such as when a sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identification of harness connectors. • Before checking voltage at connectors, check battery voltage. • After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all harness connectors are reconnected as they were.

HOW TO READ WIRING DIAGRAMS Connector symbols

GI INFOID:0000000001342949

Most of connector symbols in wiring diagrams are shown from the terminal side. • Connector symbols shown from the terminal side are enclosed by a single line and followed by the direction mark. • Connector symbols shown from the harness side are enclosed by a double line and followed by the direction mark. • Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to PG section, “Description”, “HARNESS CONNECTOR”.

H SAIA0257E

• Male and female terminals Connector guides for male terminals are shown in black and female terminals in white in wiring diagrams.

PRECAUTIONS < PRECAUTION >

PRECAUTION

PRECAUTIONS Description

INFOID:0000000001342964

Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000001342965

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SR and SB section of this Service Manual. WARNING: • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SR section. • Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000001342966

NOTE: • Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables. • After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables. • Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results. This vehicle is equipped with a push-button ignition switch and a steering lock unit. If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned. If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure below before starting the repair operation.
