Acceleration Sensor Stuck Malfunction (C1232,C1243,C1245)
DESCRIPTION
The skid control ECU (brake actuator assembly) receives signals from the yaw
rate and acceleration sensor (airbag sensor assembly) via the CAN communication
system.
The airbag sensor assembly has a built-in acceleration sensor and detects the
vehicle condition.
