- Side radar RH
- Harness connectors B239 and B63
2. Check the continuity between the side radar RH harness connector and the harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the main line between the side radar RH and the harness connector B239.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of side radar LH.
2. Check the continuity between the harness connector and the side radar LH harness connector.





Is the inspection result normal?
YES (Present error)-Check CAN system type decision again.
YES (Past error)-Error was detected in the main line between the side radar RH and the side radar LH.
NO - Repair the main line between the harness connector B63 and the side radar LH.
