W/Harness Inspection

HEV Motor System
P0A38 Generator Temperature Sensor Circuit Low - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection




1. Many malfunctions in the electrical system are caused by poor harness(es) and terminal condition. 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?






Signal Circuit Inspection

Check short to ground in harness
1. Ignition OFF
2. Disconnect safety plug from the main battery. (Wait for more than 5 minutes after disconnecting)
3. Disconnect Generator(HSG) temperature sensor and MCU main harness connector.
4. Measure resistance between Signal terminal of MCU harness connector and chassis ground.

Specification :Infinity




5. Is the measured resistance within specifications?
