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 [09/2016 - ]: Description
The absorber control ECU (front acceleration sensor RH) receives signals from the skid control ECU (brake actuator assembly), steering angle sensor (spiral cable with sensor sub-assembly), yaw rate and acceleration sensor, transmission control ECU and ECM via CAN communication.
When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
