Monitor Description

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

When the yaw rate and acceleration sensor (airbag sensor assembly) type identification information stored by the No. 2 skid control ECU (brake actuator assembly) does not match that sent via CAN communication for a certain amount of time, the No. 2 skid control ECU (brake actuator assembly) judges that the identification signal is abnormal, the MIL is illuminated and a DTC is stored.
