DTC C14D7-1C: Multi-axis Acceleration Sensor Module "A" Supply Voltage Circuit Voltage Out of Range [12/2019 - 11/2023]: Description

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

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

This DTC is stored when the No. 2 skid control ECU (brake actuator assembly) receives a sensor supply voltage malfunction signal from the yaw rate sensor.

This DTC may be stored due to an intermittent low power source voltage.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Note
