DTC C051D-00: Multi-axis Acceleration Sensor Module "A" [12/2019 - 10/2021]: Description

WARNING: This page is about a different variant/trim than selected.

The yaw rate sensor has a built-in acceleration sensor.

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

HINT: 

If there is a malfunction in the bus lines between the yaw rate sensor and the CAN communication system, DTC U0125-87 is output. When DTC U0125-87 is output together with C051D-00, inspect and repair the trouble areas indicated by U0125-87 first.

This DTC is also output when the calibration has not been completed.
