TEST VALUE AND TEST LIMIT (GST ONLY — NOT APPLICABLE TO CONSULT-II) The following is the information specified in Mode 6 of SAE J1979. The test value is a parameter used to determine whether a system/circuit diagnostic test is “OK” or “NG” while being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the maximum or minimum value and is compared with the test value being monitored. Items for which these data (test value and test limit) are displayed are the same as SRT code items. These data (test value and test limit) are specified by Test ID (TID) and Component ID (CID) and can be displayed on the GST screen.
