DTC C051D-54: Multi-axis Acceleration Sensor Module "A" Missing Calibration; DTC C1210-54: Yaw Rate Sensor Missing Calibration [12/2019 - ]: Description

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

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

HINT: 

If a communication error with the yaw rate and acceleration sensor (airbag sensor assembly) is detected, DTCs U0125-87 and/or U0151-87 are stored.

If a DTC related to the CAN communication line is output, first troubleshoot the CAN communication line.

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

DTC No. Detection Item DTC Detection Condition Trouble Area
