MIL Circuit

CIRCUIT DESCRIPTION

If the ECM detects trouble, the MIL lights up. At this time, the ECM records a DTC in memory.

HINT: When the ignition switch is ON and "READY" indicator light is OFF, the bulb check of the "MIL" is performed ("MIL" is ON).

When "MIL" is ON, but the DTC of the engine is not memorized, it may be because of HV control system abnormality, so check HV control system beforehand.
