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 [10/2014 - ]: Description

The absorber control ECU receives signals from the skid control ECU (brake actuator assembly), steering sensor, airbag ECU assembly (built into acceleration sensor) and ECM via CAN communication.

When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.
