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.

* : If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. ECM does not detect the
switch is ON even if the switch does turn ON. Therefore, the ECM does not supply power to light up the lamp.
* : If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. ECM does not detect the switch
is ON even if the switch does turn ON. Therefore, the ECM does not control ground to light up the lamp.
