DTC U0073/94: Control Module Communication Bus OFF; DTC U0123/62: Lost Communication with Yaw Rate Sensor Module; DTC U0124/95: Lost Communication with Lateral Acceleration Sensor Module; DTC U0126/63: Lost Communication with Steering Angle Sensor Module; DTC U0293/59: Communication Error from HV ECU [12/2013 - ]: Description

The skid control ECU receives signals from the power management control ECU, steering angle sensor (spiral cable with sensor sub-assembly), and yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.
