Controlled Power Feeds
CONTROLLED POWER FEEDS
Front Airbag System
The FCM provides power to the Occupant Restraint Control (ORC) system through two "fuseless" circuits (ORC RUN/START, and ORC RUN only).
These circuits are electronically controlled and continuously monitored for malfunctions. Power is supplied while the ignition switch is in the RUN
and START positions on pin 48 of the FCM connector, and in the RUN only position on pin 29.
Side Airbag System
The FCM provides power to the Side Impact Airbag Control Module (SIACM) system through one "fuseless" circuit. This circuit is electronically
controlled and continuously monitored for malfunctions. Power is supplied in the ignition RUN and START positions on pin 28 of the FCM
connector.
Headlamp Power
The headlamp switch is a direct input to the BCM. The BCM sends a PCI Bus message to the FCM informing it of a headlamp switch status change.
The FCM then turns on power to the headlamps through four "fuseless" circuits. These circuits are electronically controlled and continuously
monitored for malfunctions. Power is supplied to each filament in a separate circuit (RH low on pin 6, RH high on pin 4, LH low on pin 3 and LH high
on pin 5). For vehicles equipped with Daytime Running Lamps (DRL), the FCM electronically steps down the headlamp voltage to provide the
desired illumination.
EATX Power
The electronic automatic 4 speed transmission module is powered when the ignition switch is in the UNLOCK, RUN or START positions. This circuit
