DTC C051D-54: Multi-axis Acceleration Sensor Module "A" Missing Calibration; DTC C1210-54: Yaw Rate Sensor Missing Calibration [12/2021 - ]: Description

The yaw rate and acceleration sensor has a built-in airbag ECU assembly.

The No. 2 skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication.

HINT: 

If there is a malfunction in the bus lines between the yaw rate and acceleration sensor (airbag ECU assembly) and the CAN communication system, DTC U0125-87 is output. When DTC U0125-87 is output together with C051D-54 and/or C1210-54, inspect and repair the trouble areas indicated by U0125-87 first.

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