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: Description

The skid control ECU receives signals from the ECM, steering angle sensor, yaw rate and acceleration sensor (for separate type) and/or yaw rate and acceleration sensor (airbag sensor assembly) (for built-in type) via the CAN communication system.
