| DTC Code | DTC Name |
|---|---|
| C1AAD | Vehicle Information Initialization Incomplete |
DESCRIPTION
When the forward recognition camera is replaced with a new one, the new forward recognition camera attempts to store the vehicle information received from the ECM. If the forward recognition camera cannot store the vehicle information, DTC C1AAD is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C1AAD | Vehicle Information Initialization Incomplete | 2 seconds after the engine switch is turned on (IG), the vehicle information from the ECM cannot be stored. |

CAUTION / NOTICE / HINT
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.
If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.
PROCEDURE
CHECK FOR DTCs (CAN COMMUNICATION DTC OUTPUT)
The forward recognition camera communicates with the ECM via CAN communication. Confirm that the CAN communication system is functioning normally before proceeding.
