Lexus NX: Software Incompatibility with Body Control Module Invalid/Incompatible Software Component (U032257)

Lexus NX Service Manual / Engine & Hybrid System / Cruise Control / Front Camera System / Software Incompatibility with Body Control Module Invalid/Incompatible Software Component (U032257)

DESCRIPTION

The forward recognition camera receives vehicle specification information from the main body ECU (multiplex network body ECU) via the CAN communication line. When the value of the vehicle specification information sent from the main body ECU (multiplex network body ECU) does not match the value stored by the forward recognition camera, the forward recognition camera outputs U032257.

DTC No.

  • Front radar sensor system
  • Main body ECU (multiplex network body ECU)
  • Forward recognition camera

CAUTION / NOTICE / HINT

NOTICE:

  • Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
  • 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 it 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, be sure to perform forward recognition camera adjustment.

    HINT:

    Forward recognition camera adjustment can be performed by using either "One Time Recognition" or "Sequential Recognition".
