W/Harness Inspection

Tire Pressure Monitoring
C2511 Diagnostic(TPMS) Lamp Circuit Failure - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

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






Control Circuit Inspection

[Chcek Short to battery]
1. Ignition "OFF"
2. Disconnect instrument cluster connector and TPMS receiver connector.
3. Ignition "ON".
4. Measure voltage between TPMS check lamp control terminal of TPMS receiver harness connector and chassis ground.

Specification :Approx. 0 Ohms




5. Is the measured voltage within specifications?





[Chcek Short to ground]
1. Ignition "OFF"
2. Disconnect instrument cluster connector and TPMS receiver connector.
3. Measure resistance between TPMS check lamp control terminal of TPMS receiver harness connector and chassis ground.

Specification :Infinity




4. Is the measured resistance within specifications?





[Chcek Open]
1. Ignition "OFF"
2. Disconnect instrument cluster connector and TPMS receiver connector.
3. Measure resistance between TPMS check lamp control terminal of TPMS receiver harness connector and TPMS check lamp control terminal of instrument cluster harness connector.

Specification :Approx. 0 Ohms




4. Is the resistance measured within specifications?
