Power Circuit Inspection

1. Ignition "OFF".
2. Disconnect RCV Control connector.
3. Ignition "ON" & Engine "OFF".
4. Measure voltage between power terminal of the RCV Control harness connector and chassis ground.

Specification :B+




5. Is voltage within the specification?






Signal Circuit Inspection

Check for short to ground in control circuit
1. Ignition "OFF".
2. Disconnect RCV Control connector and ECM connector.
3. Measure resistance between control terminal of the RCV Control harness connector and chassis ground.

Specification :Infinite




4. Is resistance within the specification?





Check for open in Control harness
1. Ignition "OFF".
2. Measure resistance between signal terminal of sensor harness connector and RCV Control terminal of the PCM harness connector.

Specification :Approx. 0Ohms




3. Is resistance within the specification?






Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
