Abbreviations for Quick Reference of “DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE”
IGN: ON

: Turning the ignition switch ON is required for checking the function of the sensor, switch, solenoid and circuit.

RUNNING : Running engine is required for checking the function of the sensor, switch, solenoid and circuit.
LIFTING

: Lifting up the vehicle, running engine and spinning wheels are required.

DRIVING : Driving the vehicle in the specified pattern is required.

Abbreviations for Quick Reference of “OVERALL FUNCTION CHECK”
IGN: ON

: Turning the ignition switch ON is required for the ECM to detect a malfunction (if one exists).

RUNNING : Running engine is required for the ECM to detect a malfunction (if one exists).

This is Quick Reference of “DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE”.
Details are described in each specific TROUBLE DIAGNOSIS.

*2:

●

The “OVERALL FUNCTION CHECK” is a simplified and effective way to inspect a component or circuit.
In some cases, the “OVERALL FUNCTION CHECK” is used rather than a “DIAGNOSTIC TROUBLE CONFIRMATION PRO-
CEDURE”.
When no DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE is available, the “NG” result of the OVERALL FUNCTION
CHECK can be considered to mean the same as a malfunction item detection.

●

During an “NG” OVERALL FUNCTION CHECK, the malfunction item might not be confirmed.

●

This is Quick Reference of “OVERALL FUNCTION CHECK”.
Details are described in each specific TROUBLE DIAGNOSIS.

*3: CONSULT-II may not detect, but self-diagnostic results are available with MI.
