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 all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Has a problem been found?

	▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Ground Circuit Inspection" procedure.

Ignition switch "OFF"

Refer to "Shop Manual" and disconnect RPS connector.

Ignition switch "ON"

Measure the voltage between Pin No. 1 (Power) terminal of RPS harness connector and chassis ground.

Is the measured value within specification?

	▶ Go to "Ground Inspection" procedure.
	▶ Inspect and repair open or short in circuit, and then go to "Verification of Vehicle Repair" procedure.

Ignition switch "OFF"

Disconnect battery (-) cable.

Refer to "Shop Manual" and disconnect RPS connector.

Measure the resistance between Pin No. 3 (Ground) terminal of RPS harness connector and chassis ground.

Re-connect battery (-) cable.

Refer to "Shop Manual" and disconnect RPS connector.

Ignition switch "ON"

Measure the voltage between Pin No. 1 (Power) terminal of RPS harness connector and chassis ground.(A)

Measure the voltage between Pin No. 1 (Power) terminal and Pin No. 3 (Ground) terminal of RPS harness connector.(B)

Is the measured value within specification?

	▶ Go to "Signal Circuit Inspection" procedure.
	▶ Inspect and repair open or short in circuit, and then go to "Verification of Vehicle Repair" procedure.

Ignition switch "OFF"

Refer to "Shop Manual" and disconnect RPS connector.

Ignition switch "ON"

Measure the voltage between Pin No. 2 (Signal) terminal of RPS harness connector and chassis ground.

Is the measured value within specification?

	▶ Go to "Component Inspection" procedure.
	▶ Inspect and repair open or short in circuit, and then go to "Verification of Vehicle Repair" procedure.
