BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for Gasoline Model) C14D71C Multi-axis Acceleration Sensor Module "A" Supply Voltage Circuit Voltage Out of Range

DESCRIPTION

The airbag ECU 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 yaw rate and acceleration sensor (airbag ECU assembly).

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
C14D71C	Multi-axis Acceleration Sensor Module "A" Supply Voltage Circuit Voltage Out of Range	Vehicle speed is 6 km/h (4 mph) or more and yaw rate and acceleration sensor power supply malfunction signal is received for 1 second or more.	· Wire harness or connector · Yaw rate sensor (airbag ECU assembly)
