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?
YES
1) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Go to "Signal Circuit Inspection" procedure.

Signal Circuit Inspection

1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS connector and vehicle speed sensor connector.
3. Measure resistance between "17" terminal of the TPMS harness connector and "3" terminal of the vehicle speed sensor harness connector.
A. Specification : 0 Ohm




4. Is the measured resistance within specifications?
YES
1) Check for short circuit between TPMS harness connector and vehicle speed sensor harness connector.
2) If harness condition is OK, replace vehicle speed sensor and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check for open circuit between TPMS harness connector and vehicle speed sensor harness connector.
2) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
