8-558 Keyless Entry
Rear Compartment Lid Release
Automatic Transmission
Voltage is applied at all times from the PWR ACCY
fuse througt, circuit 640 to the normally open contacts
of the rear compartment lid release relay. When the
rear compartment lid release button on the remote
control door lock transmitter is pressed twice, voltage
is applied from the body control module (BCM)
through circuit 253 to the coil of the. rear compartment
lid release relay. If the transmission is in the PARK
or NEUTRAL position, the relay is energized. The relay
then applies battery voltage through circuit 56 to the
rear compartment lid release actuator. Ground is
applied from G400 through circuit 1550 to the
actuator. The rear compartment lid opens.
Manual Transmission
Voltage is applied at all times from the PWR ACCY
fuse through circuit 640 to the normally open contacts
of the rear compartment lid release relay. When the
rear compartment lid release button on the remote
control door lock transmitter is pressed twice, voltage
is applied from the body control module (BCM)
through circuit 253 to the coil of the rear compartment
lid release relay. If the park brake is set, the park
brake switch is closed and the relay is energized. The
relay then applies battery voltage through circuit 56
to the rear compartment lid release actuator. Ground is
applied from G400 through circuit 1550 to the
actuator. The rear compartment lid opens.
Illuminated Entry Operation
The dome lamp (coupe) or the rear courtesy lamps
illuminate whenever a remote control door lock
transmitter unlock request is received by the body
control module (BCM). The BCM provides voltage
through circuit 149 to the dome lamp (coupe) or the
rear courtesy lamps (convertible). Ground is applied
from the BCM through circuit 15.6 to the lamps.
The lamps .illuminate whenever a remote control door
lock transmitter request is received.
With a LOCK request, the dome lamp (coupe) or the
rear courtesy lamps (convertible) are immediately
turned off. This action provides visual confirmation that
a lock function was performed.
With an unlock or a rear compartment lid release
request, the dome lamp (coupe) or the rear courtesy
lamps (convertible) are turned on. The lights remain on
for 40 seconds in order to provide illuminated entry
and hatch area illumination.
Illuminated entry is disabled when the BCM detects
ignition ON voltage.
Body and Accessories
Programming the Body Control Module
The body control module (BCM) is capable of
accepting vehicle access code (VAC) programming
from any four remote control door lock transmitters. Up
to four remote control door lock transmitters can be
programmed. When four transmitters are programmed,
they must be programmed one after the other,
during the same program sequence. Transmitters may
not be programmed simultaneously. Each.transmitter
is manufactured with a permanent VAC combination
(one of over 4 billion combinations). The code
cannot be changed for the life of the transmitter. The
BCM can only be programmed by the transmitters
while in the program mode.
Programming Procedure
Important:
• When you replace a lost or damaged transmitter,
program all of the remote control door lock
transmitters.
The first transmitter code that you program will
always be in all four memories unless additional
transmitters are programmed.
• Program the remote keyless entry. system for one
vehicle at a time.
If you program two or more vehicles and the
vehicles are close to each other, one transmitter
could be programmed .to more than . one
vehicle.
1.
Turn the ignition switch to the OFF position.
2. Remove the RADIO fuse from the fuse block.
3. Cycle the ignition switch from the OFF position to
the RUN position 3 times within 5 seconds.
The body control module (BCM) will verify entry
into the programming mode by performing
the following actions:
3.1 . Locking both of the doors
3.2. Unlocking the driver door
3.3. Releasing the rear compartment lid
4. Press and hold both the LOCK and UNLOCK
buttons on the remote control door lock
transmitter for approximately 15 seconds.
The following actions will occur:
• The BCM will confirm that the transmitter code
is programmed by performing the following
actions:
4.1. Locking both of the doors
4.2. Unlocking the driver door
4.3. Releasing the rear compartment lid
• Any transmitter code that was previously
programmed is erased.
• The BCM is programmed to the transmitter.
