GF91.60-P-4102MCU Head/thorax Bag Sensor, Component Description







A53 Driver head/thorax bag sensor
A54 Front passenger head/thorax bag sensor

Location
The head/thorax bag sensors are installed in the left and right B-pillars beneath the automatic belt retractors.

Task
The head/thorax bag sensors determine the acceleration value in the area of the B-pillar for the left or right side of the vehicle. The restraint systems control unit (N2/7) makes the decision whether to deploy the head/thorax bags based on these values.

After a successful self-test the head/thorax bag sensors continuously transmit a signal to the restraint systems control unit.
