PROCEDURE

CLEAR DTC

(a) Clear the DTCs.

Chassis > Front Recognition Camera > Clear DTCs

2.	CHECK FOR DTCs

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

HINT:

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

(b) Check for DTCs.

Chassis > Front Recognition Camera > Trouble Codes

Result	Proceed to
DTC U010087, U010187, U012687, U012987, U014087 or U015587 is output	A
DTCs are not output	B
None of the above conditions are met	C

GO TO CAN COMMUNICATION SYSTEM
