Title: CRUISE CONTROL: FRONT RADAR SENSOR SYSTEM: U030557; Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component; 2021 - 2024 MY Camry [10/2020 -        ]

DTC

U030557

Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component

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.

DTC No.

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

  • Millimeter wave radar sensor assembly
  • Forward recognition camera

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.
