TABLE A-1 MALFUNCTION INDICATOR LAMP CIRCUIT CHECK – LAMP
DOES NOT COME “ON” AT IGNITION SWITCH ON (BUT ENGINE
AT STOP)
CIRCUIT DESCRIPTION

2. Ignition switch
3. Fuse box
4. Main relay
5. Malfunction indicator lamp
in combination meter
6. “IG COIL METER” fuse
7. Monitor connector

When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM
being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the engine starts to run
and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is detected, MIL remains
ON even when the engine is running.
