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.
