B-Pillar Satellite, Left (SBSL): Sensor
An acceleration sensor for the transversal acceleration is integrated in the SBSL. The sensor provides a variable voltage. This voltage is a measurement of the vehicle's sideways acceleration.
The ignition stages are diagnosed by igniter ICs and ignited by means of ignition capacitors.
The self-diagnosis of the trigger circuits during the pre-drive check and in normal operation is the same for all satellites. (See SASL )
