WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
-
Inspect the fuses for circuits related to this system before performing the following procedure.
-
When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.
-
When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.
HINT:
Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

PROCEDURE
(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.
