Toyota Camry (XV70): Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component (U030557)
DESCRIPTION
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.

CAUTION / NOTICE / HINT
NOTICE:
- 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 has been replaced with a new one, it is necessary to perform millimeter wave radar sensor assembly beam axis alignment and to clear the vehicle control history. Before performing the Driving Adjustment, make sure to read Before Starting Driving Adjustment.
HINT:
Beam axis alignment of the millimeter wave radar sensor assembly can be performed using either Triangle Target, Flat Surface Target or Driving Adjustment.

- 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.
- 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.

System Voltage Circuit Short to Ground or Open (P056014)
DESCRIPTION The battery supplies electricity to the ECM even when the engine switch is off. This power allows the ECM to store data such as DTC history and freeze frame data. If the battery voltage falls below a minimum level, the stored ECM data will be cleared and the ECM will determine that there
