Moving Driver's Side Carrier From A-Pillar (Front Limit Switch) to B-Pilllar (Rear Limit Switch)

To move the carrier from front body pillar (A-Pillar) to center body pillar (B-Pillar) when front door is closed (pin 13 floating/not grounded), and the ignition key in the ON position (pin 25 high), the passive restraint control module will check B-Pillar limit switch (pin 18).

If B-Pillar limit switch is not activated (pin 18 floating/not grounded), the passive restraint control module will apply power to safety belt retractor motor. This will send carrier from A-Pillar to B-Pillar (Voltage to Pin Nos. 2 and 17, Pin Nos. 3 and 4 grounded). The carrier will travel toward the B-pillar until the B-pillar limit switch is activated (Pin No. 18 is grounded). If Pin 18 is grounded, the carrier will not move.
