Inspection/Repair - W/Harness Inspection

Terminal and 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?






Signal Circuit Inspection

1. Check CAN high circuit
(1) IG "ON" & ENG "OFF"
(2) Connect GDS and select Scope meter function.
(3) Measure signal waveform of PSM CAN High line.

Specification : Refer to signal waveform and data













(4) Is the measured signal waveform of CAN high circuit normal ?





2. Check CAN Low circuit
(1) IG "ON" & ENG "OFF"
(2) Connect GDS and select Scope meter function.
(3) Measure signal waveform of PSM CAN Low line.

Specification : Refer to signal waveform and data













(4) Is the measured signal waveform of CAN low circuit normal ?
