1997 CADILLAC DEVILLE ECU

Downloaded from www.Manualslib.com manuals search engine The following steps explain how to remove the trunk
storage system for cleaning or in case you need to access
the spare tire. Follow
all of these steps if the storage
system
is in the closed position. Begin with Step 2 if the
system is already open.
1. Open the storage system by pulling up on the handle
located in the carpeted area. This allows the unit to
snap into place.
Fold the divider walls open.
2. Remove the rectangular access panel from the floor
of the storage system. The access panel should
unsnap by hand.
3. Center the storage system access hole over the area
where the spare tire
is secured by the retainer.
Position the storage system as needed and then
remove the retainer (turn the retainer
counterclockwise to remove it).
4. Replace the access panel and remove the
storage system.
Trunk Lid Automatic Pull-Down Feature
' A CAUTION:
Your car has an automatic pull-down feature that
helps close the trunk electronically. Your fingers can be trapped under the trunk lid as it goes
down. Your fingers could be injured, and you
would need someone
to help you free them. Keep
your fingers away from the trunk lid as you close
it and as it is going down.
With the automatic pull-down feature, you never have to
slam the trunk lid in order to close the trunk. Instead,
gently lower the trunk lid until
it is nearly shut -- the
automatic pull-down unit will take over and lock the
trunk firmly.

Theft-Deterrent System (If Equipped)
SECURITY
If the ignition is off and
any door is open, the
SECURITY light will flash,
reminding you to activate
the system (the light will
also flash if the battery
has been disconnected
and reconnected).
1. Open the door.
2. Lock the door using the power door lock or the RKE
system. The
SECURITY light should come on and
stay on.
3. Close all the doors. The SECURITY light should go
off within approximately 30 seconds.
The horn will sound and the lamps
will flash for about
30 seconds when the door or trunk is opened without the
key or RKE system. The horn also sounds if the locks
are damaged.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or
use the manual door
lock. It activates only
if you use a power door lock
switch or the RKE system.
To avoid activating the alarm by accident:
The vehicle should be locked with the door key after
the doors are closed if you don’t want to activate the
theft-deterrent system.
Always unlock a door with a key or use the RKE
system. (Pressing the unlock button on the RKE
transmitter disables the theft-deterrent system.)
Unlocking a door any other way will activate the
alarm. Cycling
the ignition without disarming the
theft-deterrent system will also activate the alarm.
If you activate the alarm by accident, unlock any door
with your key. You can also turn off the alarm by using
the RKE system. The alarm won’t stop
if you try to
unlock a door any other way.

1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the RKE system and close the door. Wait
30 seconds until the
SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see “Fuses and Circuit Breakers” in the\

Index.
If the fuse does not need to be replaced, you may
need to have your Cadillac serviced.
To reduce the possibility of theft, always activate the
theft-deterrent system when leaving your vehicle.

Note that the RKE transmitter can’t be used to open the
trunk or fuel door if the VALET button is pressed in.

front surface
of the universal transmitter so that you
can still
see the red light.
4. Using both hands, press the hand-held transmitter
button and the desired button on the universal
transmitter. Continue to press both buttons through Step 5.
5. Hold down both buttons until you see the red light
on the universal transmitter flash slowly and then
rapidly. The rapid flashing, which could take up to
90 seconds, indicates that the universal transmitter
has been programmed. Release both buttons once the
light starts to flash rapidly.
If
you have trouble programming the universal
transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand-held transmitter is not dead.
If you still cannot
program it, rotate the hand-held transmitter end over end
and try again. The universal transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards. If you cannot
program the transmitter after repeated attempts, consult
your Cadillac dealer.
Be sure to keep the original hand-held transmitter in case
you need to erase and reprogram the universal transmitter.
Note to Canadian Owners: During programming, the
hand-held transmitter may stop transmitting after one or
two seconds.
If you are programming from one of these
transmitters,
you should press and re-press the button on
the hand-held transmitter every two seconds without
ever releasing the button on the universal transmitter.
Release both buttons when the red light on the universal
transmitter begins to flash rapidly.
Operating the Transmitter
Press and hold the appropriate button on the universal
transmitter. The red light comes on while the signal is
being transmitted.
Note that the universal transmitter
is disabled when the
VALET button inside the glove box is activated. For
more information, see “Security Override” earlier
in
this section.
Also note that if the hand-held transmitter appears to
program the universal transmitter but does not open
your garage door, and if the garage door opener was
manufactured after 1995, the garage door opener may
have a “rolling code” system.
A rolling code system
changes the code
of the garage door opener every time
you open or close the garage door.
