DTC U0100: Lost Communication with ECM / PCM "A"; DTC U0101: Lost Communication with TCM; DTC U0122: Lost Communication With Vehicle Dynamics Control Module; DTC U0124: Lost Communication with Lateral Acceleration Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module [09/2015 - ]: Description
The absorber control ECU (rear acceleration sensor) receives signals from the skid control ECU (brake actuator assembly), steering angle sensor, airbag sensor assembly (acceleration sensor) *1, yaw rate sensor assembly (acceleration sensor) *2 and ECM via CAN communication.
When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
