The millimeter wave radar sensor assembly receives vehicle information from the forward recognition camera via CAN communication.
If the vehicle information stored in the forward recognition camera differs from that stored in the millimeter wave radar sensor assembly, the millimeter wave radar sensor assembly stores this DTC.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U030557 | Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component | When the ignition switch is ON, the vehicle information stored in the millimeter wave radar sensor assembly differs from that received from the forward recognition camera | ·

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, be sure to adjust the millimeter wave radar sensor assembly beam axis, perform front radar acceleration sensor calibration, and clear the vehicle control history for each system.
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.
Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.
