•
Interior Lighting Control - The BCM monitors inputs from the interior lighting switch, the door ajar switches,
the flip-up glass ajar switch, the tailgate ajar switch, the cargo lamp switch, the reading lamp switches, and the
RKE system to provide courtesy lamp control. This includes support for timed illuminated entry with theater-
style fade-to-off and courtesy illumination defeat features.
•
Intermittent Wipe and Front Wiper System Control - The BCM monitors inputs from the front wiper and
washer switch and the front wiper motor park switch to provide front wiper system control through the wiper
on/off and high/low relays. This includes support for adjustable intermittent wipe, mist wipe (also known as
pulse wipe), and wipe-after-wash features.
•
Key-In-Ignition Switch Status - The BCM monitors and transmits the status of the key-in-ignition switch.
•
Panic Mode - The BCM provides support for the RKE system panic mode feature.
•
Parade Mode - The BCM provides a parade mode (also known as funeral mode) that allows the interior Vac-
uum Fluorescent Displays (VFD) to be illuminated at full intensity while driving in daylight with the exterior
lamps On.
•
Power Locks - The BCM monitors inputs from the power lock switches and the RKE system to provide control
of the power lock motors through outputs to the lock, unlock, and driver unlock relays. This includes support
for rolling door locks (also known as automatic door locks) and a door lock inhibit mode.
•
Programmable Features - The BCM provides support for several standard and optional programmable fea-
tures, including: rolling door locks, headlamp time delay interval, RKE driver-door-only or unlock-all-doors, RKE
optical chirp, and RKE audible chirp.
•
Remote Keyless Entry - The BCM provides support for the RKE system features, including support for the
RKE Lock, Unlock (with optional driver-door-only unlock, and unlock-all-doors), rear flip-up glass control, Panic,
audible chirp, optical chirp, and illuminated entry modes.
•
Rolling Door Locks - The BCM provides support for the power lock system rolling door locks feature (also
known as automatic door locks).
•
Tailgate and Flip-Up Glass Ajar Status - The BCM monitors and transmits the status of the tailgate and rear
flip-up glass ajar switches.
•
Remote Radio Switch Interface - The BCM monitors and transmits the status of the optional remote radio
switches.
•
Self-Diagnostics - The BCM provides support for diagnostics through communication with a diagnostic scan
tool over the PCI data bus network. Each analog and digital input can be verified, and each output can be
actuated through the use of this diagnostic protocol. The BCM also stores Diagnostic Trouble Codes (DTCs) to
assist in the troubleshooting of this unit.
•
Vacuum Fluorescent Display Synchronization - The BCM transmits panel lamp intensity data which allows
modules with Vacuum Fluorescent Displays (VFD) to coordinate their illumination intensity.
•
Vehicle Theft Security System - The BCM monitors inputs from the door ajar switches, the tailgate ajar
switch, the flip-up glass ajar switch, the hood ajar switch (in required markets only), and the RKE system to
control the features of the optional Vehicle Theft Security System (VTSS).
Hard wired circuitry connects the BCM to the electrical system of the vehicle. These hard wired circuits are integral
to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These
circuits may be connected to each other, to the vehicle electrical system and to the BCM through the use of a
combination of soldered splices, splice block connectors, and many different types of wire harness terminal con-
nectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-
out and location views for the various wire harness connectors, splices and grounds.
Many of the electronic features in the vehicle controlled or supported by the BCM are programmable using a cus-
tomer programming procedure or a diagnostic scan tool. In addition, the BCM software is Flash compatible, which
means it can be reprogrammed using Flash reprogramming procedures. However, if any of the BCM hardware is
damaged or faulty, the entire BCM unit must be replaced.
