BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HV Model) C11791C Multi-axis Acceleration Sensor Module "A" Supply Voltage (2WD) Circuit Voltage Out of Range

DESCRIPTION

The airbag sensor with 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 sensor with ECU assembly).
