lThe ªOVERALL FUNCTION CHECKº is a simplified and effective way to inspect a component or circuit.
In some cases, the ªOVERALL FUNCTION CHECKº is used rather than a ªDIAGNOSTIC TROUBLE CONFIRMATION PRO-
CEDUREº.
When no DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE is available, the ªNGº result of the OVERALL FUNCTION
CHECK can be considered to mean the same as a malfunction item detection.
lDuring an ªNGº OVERALL FUNCTION CHECK, the malfunction item might not be confirmed.lThis is Quick Reference of ªOVERALL FUNCTION CHECKº.
