W/Harness Inspection

Power Distribution Module
B1989 ESCL Ground Short Circuit To Battery - Inspection/Repair:_:W/Harness Inspection

Terminal & 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?






PDM Ground Circuit Inspection

Check short at ground terminal of PDM
1. IG "ON" & ENG "OFF".
2. Measure voltage between ESCL ground terminal of PDM and chassis ground.
(Measure the voltage while ESCL doesn't work.)

Specification :Approx. 0 V




3. Is the measured voltage within specifications?





Check short to power on ESCL GND circuit
1. IG "ON" & ENG "OFF"
2. Disconnect the connectors of IPM, PDM, ESCL.
3. Measure voltage between ESCL ground terminal and chassis ground.

Specification :Approx. 0 V




4. Is the measured voltage within specifications?
