Toyota Corolla Cross: Software Incompatibility with Body Control Module Not Programmed (U032251)

DESCRIPTION

Forward recognition camera receives vehicle specification information from the main body ECU (multiplex network body ECU) via CAN communication line. If the forward recognition camera cannot confirm the vehicle specification information based on vehicle specification information sent from the main body ECU (multiplex network body ECU), the forward recognition camera stores DTC U032251.

CAUTION / NOTICE / HINT

NOTICE:

• 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 has been replaced with a new one, make sure to clear all stored vehicle control history of each system and the forward recognition camera beam axis alignment data.

  HINT:

  Forward recognition camera beam axis alignment can be performed by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment Value Write".
