Code C1419 Description

The Skid Control ECU (Brake Actuator Assembly) receives signals from the Yaw Rate and Acceleration Sensor (Airbag Sensor Assembly) via the Control Area Network (CAN) communication system. The Airbag Sensor Assembly has a built-in Yaw Rate and Acceleration Sensor and detects the vehicle's condition. If there is trouble in the bus lines between the Acceleration Sensor (Airbag Sensor Assembly) and the CAN communication system, DTC U0124 (Lost Communication with Lateral Acceleration Sensor Module) is set. This Diagnostic Trouble Code (DTC) is also output when calibration has not been completed.
