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: Lost Communication with EV Control System [09/2013 - ]: Description

The skid control ECU (brake booster with master cylinder assembly) receives the signals from the power management control ECU, drive inverter ECU (electric vehicle traction motor assembly), steering sensor, and yaw rate sensor assembly via the CAN communication system.
