DTC Code DTC Name
U0100 Lost Communication with ECM / PCM "A"
U0101/71 Lost Communication with TCM
U0122/71 Lost Communication with Vehicle Dynamics Control Module
U0124 Lost Communication with Lateral Acceleration Sensor Module
U0126/71 Lost Communication with Steering Angle Sensor Module
U0130/71 Lost Communication with Steering Effort Control Module
U0132 Lost Communication with Suspension Control ECU

DESCRIPTION

The suspension control ECU receives signals from the skid control ECU, steering control ECU, steering angle sensor, yaw rate and acceleration sensor, ECM and TCM via CAN communication. When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.

    2. Perform a road test.

    3. Check for DTC Click here.

      Result
      Condition Proceed to
      DTC is output (for LHD) A
      DTC is output (for RHD) B
      DTC is not output C

      Tech Tips

      If a CAN communication malfunction DTC and a related sensor malfunction DTC are output at the same time, the CAN communication malfunction must be repaired before troubleshooting the sensor malfunction DTC.
