STEP 1. Resistance measurement at the power drive unit connector and the PHEV-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the power drive unit connector (KLN1 terminal) and the PHEV-ECU connector (KLN1 terminal).OK: The resistance should be 2 ohms or less.
Is the check result normal?
Go to Step 2. Replace the connector(s) or wiring harness.
