Circuit Description

Malfunction Indicator Light (MIL) should always be illuminated steady whenever ignition is turned ON, engine not running position. Ignition voltage is supplied to MIL indicator bulb through the C-10 METER GAUGE fuse located in dash fuse box. PCM illuminates MIL by grounding the MIL driver. MIL should not remain illuminated when engine is running and no DTCs are stored. A steady illuminated MIL when engine is running and DTCs stored, indicates a short to ground in MIL driver circuit.
