DTC U0073: Control Module Communication Bus OFF; DTC U0100: Lost Communication with ECM / PCM; DTC U0123: Lost Communication with Yaw Rate Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module; DTC U0142: Lost Communication with Body Control Module "B" [02/2017 - ]: Description
The skid control ECU (brake actuator assembly) receives signals from the ECM, steering angle sensor, yaw rate and acceleration sensor (airbag sensor assembly) and main body ECU (multiplex network body ECU) via CAN communication.
