ECU CADILLAC CTS 2009 2.G Owner's Guide

Immobilizer Operation (Key Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The theft-deterrent system is disarmed when the key is
turned to ON/RUN.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The key uses a transponder that matches an immobilizer
control unit in your vehicle and automatically disarms the
system. Only the correct key will start the vehicle. If the
key is ever damaged, you may not be able to start your
vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time, you
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-115. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer who can service the theft-deterrent system
and have a new key made.It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement key.
Up to 10 keys can be programmed for the vehicle.
The following procedure is for programming additional
keys only.
To program a new key do the following:
1. Verify that the new key has
1stamped on it.
2. Insert the current driver’s key in the ignition and
start the engine. If the engine will not start see
your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within ve seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off once the key has
been programmed. It may not be apparent that
the security light went on due to how quickly the key
is programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
In an emergency, contact Cadillac Roadside Service.
SeeRoadside Service on page 7-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Immobilizer Operation
(Keyless Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition
control knob is pushed in and a valid transmitter is
found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in your
vehicle. Only a correctly matched keyless access
transmitter will start the vehicle. If the keyless access
transmitter is ever damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your immobilizer system. Turn the ignition
control knob off and try again.If the ignition control knob does not rotate, and the
keyless access transmitter appears to be undamaged,
try another keyless access transmitter. Or, you may
try placing the transmitter in the transmitter pocket
located in the center console. See “Electronic Key Not
Detected” underDIC Warnings and Messages on
page 3-58. At this time, you may also want to check the
fuse. SeeFuses and Circuit Breakers on page 5-115.
If the ignition control knob still does not rotate with
the other transmitter, your vehicle needs service. If the
ignition control knob does rotate, the rst transmitter
may be faulty. See your dealer/retailer who can service
the theft-deterrent system and have a new keyless
access transmitter programmed to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-8.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-110.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled after driving forward at least
15 mph (25 km/h), take the vehicle to your dealer/retailer.

2-60

Keep the original hand-held transmitter for use in other
vehicles as well as for future Universal Home Remote
programming. It is also recommended that upon the
sale of the vehicle, the programmed Universal Home
Remote buttons should be erased for security purposes.
See “Erasing Universal Home Remote Buttons” later in
this section.
When programming a garage door, park outside of the
garage. Park directly in line with and facing the garage
door opener motor-head or gate motor-head. Be sure that
people and objects are clear of the garage door or gate
that is being programmed.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.
Programming the Universal Home
Remote System
For questions or help programming the Universal
Home Remote System, call 1-800-355-3515 or
go to www.homelink.com.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before starting. Otherwise, the device will time out
and the procedure will have to be repeated.To program up to three devices:
1. From inside the vehicle, press and hold down the
two outside buttons at the same time, releasing
only when the Universal Home Remote indicator
light begins to ash, after 20 seconds. This step
will erase the factory settings or all previously
programmed buttons.
Do not hold down the buttons for longer than
30 seconds and do not repeat this step to program
the remaining two Universal Home Remote buttons.
2. Hold the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the Universal
Home Remote buttons while keeping the indicator
light in view. The hand-held transmitter was supplied
by the manufacturer of your garage door opener
receiver (motor head unit).
