B-Pillar Satellites
The two MRSA modules (multiple restraint system external satellites) which were previously positioned under the seats, have been replaced by B-pillar satellites. Each B-pillar satellite consists of a lateral acceleration sensor and a linear acceleration sensor.
As with the up-front sensors, signal transmission is cyclic. The B-pillar satellites detect side, front and rear impacts.
The left and right B-pillar satellites are identical.
