Lexus NX: Software Incompatibility with Body Control Module Not Programmed (U032251)
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 forward recognition camera is unable to determine the vehicle information from the vehicle specification information sent from the main body ECU (multiplex network body ECU), the forward recognition camera outputs U032251.

| U032251 | Software Incompatibility with Body Control Module Not Programmed | The forward recognition camera is unable to determine the vehicle information from the vehicle specification information sent from the main body ECU (multiplex network body ECU) | Forward recognition camera |
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 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.
