Many malfunctions in the electrical system are caused by poor harness and terminals.

Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

Ignition "OFF".

Refer to "Shop Manual" and disconnect Purge Control Solenoid Valve connector.

Ignition "ON".

Measure voltage between Pin No. 1 (Power) terminal of Purge Control Solenoid Valve harness connector and chassis ground.

Is measured value within specification?

	▶ Go to "Control Circuit Inpsection" procedure.
	▶ Repair open or short in power circuit between Purge Control Solenoid and Battery and then go to "Verification of vehicle Repair" procedure.

Ignition "OFF".

Refer to "Shop Manual" and disconnect Purge Control Solenoid Vavle connector.

Ignition "ON".

Measure voltage between Pin No. 2 (Control) terminal of Purge Control Solenoid Valve harness connector and chassis ground.

Ignition "OFF".

Re-connect Purge Control Solenoid Valve connector.

Connect VMI to GDS and set up an oscilloscope as follow (2-channel);

Channel A (+) : Pin No. 2 (Control) terminal of Purge Control Solenoid Valve.

Channel A (-) : Ground

Ignition "ON" & Engine "ON".

Testing Condition : Idle

Is measured value within specification?

	▶ Go to "Component Inpsection" procedure.
	▶ Repair open in control circuit between Purge Control Solenoid Valve and PCM and then go to "Verification of vehicle Repair" procedure.
