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 "Speedometer Inspection" procedure.

Speedometer Inspection

1. Ignition "ON" & Engine "ON".
2. With vehicle raised on a lift , start the engine and place transaxle in Drive. Let vehicle idle and verify speedometer indicates Approx. 10 Km/h or more (6 mph or more) on the instrument cluster.
3. Does the speedometer indicate normally ?
YES
1) Check for open circuit between "11" terminal of the TPMS connector and "13" terminal of the joint connector [JM02]
2) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check for open circuit between "24" terminal of the Instrument Cluster connector [M01-B] and "12" terminal of the joint connector [JM02]
2) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
3) If harness condition is OK, Go to "Signal Circuit Inspection [A/T or M/T]" procedure.

Signal Circuit Inspection [A/T]

1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS connector and PCM connector.
3. Measure resistance between "11" terminal of the TPMS harness connector and "53" terminal of the PCM harness connector.
A. Specification : 0 ohms




4. Is the measured voltage within specifications ?
YES
1) Check for short circuit between TPMS harness connector and PCM harness connector.
2) If harness condition is OK, Refer to DTC guide of the engine system [P0501]. P0501
NO
1) Check for open circuit between TPMS harness connector and PCM harness connector.
2) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.

Signal Circuit Inspection [M/T]

1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS connector and vehicle speed sensor connector.
3. Measure resistance between "11" terminal of the TPMS harness connector and "1" terminal of the vehicle speed sensor harness connector.
A. Specification : 0 ohms




4. Is the measured voltage 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.
