STEP 2. Resistance measurement at LIN bus line
Check if the LIN bus line is shorted to ground.(1) Disconnect the PHEV-ECU connector, the battery management unit (BMU) connector or the parking lock driver unit connector, and measure at the wiring harness side.
(2) Check the continuity in LIN1 line between the PHEV-ECU connector and body ground.OK: No continuity (1 kΩ or more)
(3) Check the continuity in KLNC line between the battery management unit (BMU) connector and body ground.OK: No continuity (1 kΩ or more)
Is the check result normal?
Go to Step 3. Repair the connector or wiring harness.
