DESCRIPTION
The ECM determines the vehicle inclination based on a signal from the airbag sensor assembly (yaw rate and acceleration sensor). If a malfunction of the airbag sensor assembly (yaw rate and acceleration sensor) is determined based on a malfunction signal from the skid control ECU (brake actuator assembly), the ECM stores this DTC.
