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 "INPUT SPEED SENSOR2" connector.

Measure voltage between "Power" terminal of the INPUT SPEED SENSOR2 harness connector and chassis ground.

[1. Signal, 2. -, 3. Power]

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 "INPUT SPEED SENSOR2" connector.

Measure resistance between "Signal" terminal of the INPUT SPEED SENSOR2 harness connector and chassis ground.

[1. Signal, 2. -, 3. Power]

Is voltage within specifications?

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