DTC C051D-54: Multi-axis Acceleration Sensor Module "A" Missing Calibration; DTC C1210-54: Yaw Rate Sensor Missing Calibration [08/2019 - ]: Description

The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (air bag sensor assembly) via the CAN communication system.

The air bag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If there is trouble in the bus lines between the yaw rate and acceleration sensor (air bag sensor assembly) and the CAN communication system, the DTC U0125-87 is output.

The DTCs are also output when the calibration has not been completed.
