DESCRIPTION
for Gasoline Model:
- The millimeter wave radar sensor assembly receives vehicle specification information from the main body ECU (multiplex network body ECU) and ECM via the CAN communication line. If the millimeter wave radar sensor assembly cannot confirm the vehicle specification information sent from the main body ECU (multiplex network body ECU) and ECM, the millimeter wave radar sensor assembly stores DTC U032251.
- The millimeter wave radar sensor assembly receives vehicle specification information from the main body ECU (multiplex network body ECU) and ECM via the CAN communication line. If the vehicle specification information stored in the millimeter wave radar sensor assembly does not match the vehicle specification information sent from the main body ECU (multiplex network body ECU) and ECM, the millimeter wave radar sensor assembly stores DTC U032257.
for HV Model:
- The millimeter wave radar sensor assembly receives vehicle specification information from the main body ECU (multiplex network body ECU) and hybrid vehicle control ECU assembly via the CAN communication line. If the millimeter wave radar sensor assembly cannot confirm the vehicle specification information sent from the main body ECU (multiplex network body ECU) and hybrid vehicle control ECU assembly, the millimeter wave radar sensor assembly stores DTC U032251.
- The millimeter wave radar sensor assembly receives vehicle specification information from the main body ECU (multiplex network body ECU) and hybrid vehicle control ECU assembly via the CAN communication line. If the vehicle specification information stored in the millimeter wave radar sensor assembly does not match the vehicle specification information sent from the main body ECU (multiplex network body ECU) and hybrid vehicle control ECU assembly, the millimeter wave radar sensor assembly stores DTC U032257.

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.
