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

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

This DTC is stored when the skid control ECU (brake actuator assembly) receives a sensor supply voltage malfunction signal from the acceleration sensor (airbag sensor assembly).

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

DTC No. Detection Item DTC Detection Condition Trouble Area
