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 vehicle Repair" procedure.
	▶ Go to "Power circuit inspection" procedure.

Ignition "ON" & Engine "OFF".

Disconnect the "Shift Motor" connector.

Measure voltage between "Motor Power" terminal of the Shift Motor harness connector and chassis ground.

Is voltage within specifications?

	▶ Go to "Signal circuit Inspection" procedure.
	▶ Check for open or short in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure. If signal circuit in harness is OK, Go to "Check TCM" of the "Component Inspection" procedure.

Ignition "ON" & Engine "OFF".

Disconnect the "Select Motor" connector.

Measure voltage between "7" terminal of the Shift Motor harness connector and chassis ground.

Is voltage within specifications?

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

Ignition "ON" & Engine "OFF".

Disconnect the "Shift Motor" connector.

Measure voltage between "8" terminal of the Shift Motor harness connector and chassis ground.

Is voltage within specifications?

	▶ Substitute with a known-good "Shift Motor" and check for proper operation. If the problem is corrected, replace "Shift Motor" as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Check for open/short in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure.
