PROCEDURE

1.

CHECK FOR DTCs

(a) Clear the DTCs.

Chassis > Front Recognition Camera > Clear DTCs

(b) Make sure that the DTC detection conditions are met.

HINT:

If the detection conditions are not met, the system cannot detect the malfunction.

(c) Check for DTCs.

Chassis > Front Recognition Camera > Trouble Codes
