Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damage of component.

Perform checking procedure as follows.

(1)

Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.

(2)

Check connecting condition of ECM and component connector : Check terminal separation, damage of locking device and connecting condition between terminal and wiring.

note

Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. (After checking, reconnect the pin at correct position.)

Is the problem found?

	▶ Repair the trouble causing part and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Control Circuit Inspection".

Check voltage between 'MIL Indicator control' terminal of ECM harness connector and chassis ground.

Specification : 10.5V ~ 14.5V

Jump 'MIL Indicator control' terminal of ECM harness connector and chassis ground with jumper wire.

Specification : MIL lamp "ON"

Is the measured value within specification and does MIL lamp turn ON?

▶ Go to "Component Inspection" procedure.

▶ If no voltage is detected, check MIL lamp itself and repair open / short to ground between MIL terminal of 'INSTRUMENT CLUSTER' harness connector and 'MIL Indicator control' terminal of ECM harness connector, and go to "Verification of Vehicle Repair" procedure.

▶ If the voltage is high than specification value or MIL lamp is "OFF", repair short to battery between MIL terminal of 'INSTRUMENT CLUSTER' harness connector and 'MIL Indicator control' terminal of ECM harness connector, and go to "Verification of Vehicle Repair" procedure.
