1. Measure voltage or inspect for continuity according to the Terminal Voltage Table (Reference).

  • If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under "Inspection item (s)".

2. If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, perform symptom troubleshooting.
