Toyota Yaris: Dynamic Radar Cruise Control System / Software Incompatibility with Body Control Module Not Programmed (U032251)
DESCRIPTION
If the millimeter wave radar sensor assembly cannot confirm the vehicle information (steering wheel position) sent from the main body ECU (multiplex network body ECU), the millimeter wave radar sensor assembly stores DTC U032251.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from |
U032251 | Software Incompatibility with Body Control Module Not Programmed | While the dynamic radar cruise control system is operating, the millimeter wave radar sensor assembly cannot confirm the vehicle information (steering wheel position) sent from the main body ECU (multiplex network body ECU) for approximately 6 seconds or more. | Millimeter wave radar sensor assembly | Radar Cruise2 |
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

No special break-in is necessary, but a few precautions in the first 600
miles (1,000 km) may add to the performance, economy, and life of
the vehicle.
Do not race the engine.
Do not maintain one constant speed, either slow or fast, for a long
period of time.
Do not drive constantly at full-throttle or high engine rpm for
extended periods of time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
