DTC |
U010487 |
Lost Communication with Cruise Control Module Missing Message |
DESCRIPTION
The millimeter wave radar sensor assembly communicates with the forward recognition camera via CAN communication.
If a communication error is detected between the forward recognition camera and millimeter wave radar sensor assembly, the millimeter wave radar sensor assembly stores this DTC.

- When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.
-
When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the millimeter wave radar sensor beam axis must be performed.

- 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 and a DTC may be stored.
-
If the forward recognition camera has been replaced with a new one, forward recognition camera adjustment must be performed.
HINT:
Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.
