YES
Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for loose or poor connections.
- Open wire check (B-CAN_H, B-CAN_L line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the receiving control unit connector.
Power tailgate control unit connector C (14P) - 3. Disconnect the transmitting control unit connectors.
Gauge control module 32P connector Power window master switch 37P connector Under-dash fuse/relay box connector R (16P) - 4. Check for continuity between the receiving control unit and the transmitting control unit on the B-CAN_H circuit and the B-CAN_L circuit as specified in the table while in the vehicle OFF (LOCK) mode.
Is there continuity?
YES
The B-CAN_L to B-CAN_H wire is OK. Go to step 3.
NO
Repair an open or high resistance in the B-CAN_H and/or B-CAN_L wire (S) between the receiving control unit and the transmitting control unit.
- Determine possible failure area (the receiving control unit or the transmitting control unit)
- 1. Reconnect all connectors.
- 2. Turn the vehicle to the ON mode.
- 3. Clear the DTCs with the HDS.
