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.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| 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 |
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.
When the forward recognition camera is replaced with a new one, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history (RoB) for each system.
Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: System Select / Health Check.
Check for DTCs.
DTCs are not output by any system other than the front camera system (Front Recognition Camera) and dynamic radar cruise control system (Radar Cruise2).
