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 then go to "Verification of Vehicle Repair" procedure
	▶ Go to "Power Circuit Inspection" procedure

Connect "A/T SOLENOID VALVE" connector and install device for measuring wave form

Turn on the Engine and operate Damper clutch

Measure wave form between "PCSV-C(UD)" teminal of the sensor harness connector and chassis ground.

Is measured normally operating wave form?

	▶ Go to "Signal circuit inspection" procedure
	▶ Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure

Check signal circuit open inspection

(4)

Is resistance within specifications?

	▶ Go to "Check signal circuit short Inspection" procedure
	▶ Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure

Check signal circuit short inspection

(4)

Is resistance within specifications?

	▶ Go to "Ground circuit Inspection" procedure.
	▶ Check for short to ground in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure

Ignition "OFF"".

Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.

Measure resistance between ground termial of ATM SOLENOID VALVE harness connector and chassis ground.

Is resistance within specifications?

	▶ Go to "Component Inspection" procedure.
	▶ Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure.
