Acceleration Sensor Internal Circuit (C1419,C1435)
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 yaw rate and acceleration sensor and
detects the vehicle condition.
