ECU CHEVROLET IMPALA 2007 9.G Service Manual

Read the instructions completely before attempting
to program the transmitter. Because of the steps
involved, it may be helpful to have another person
available to assist you in programming the
transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as,
for future programming. You only need the original
remote control transmitter for Fixed Code
programming. It is also recommended that upon
the sale or lease termination of the vehicle, the
programmed buttons should be erased for security
purposes. See “Erasing Universal Home Remote
Buttons” later in this section.
When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or
security device you are programming.
Programming Universal Home
Remote — Rolling Code
Most garage door openers sold after 1996 are
Rolling Code units.Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions,
the device will time out and you will have to repeat
the procedure.
Follow these steps to program up to three devices:
1. From inside the vehicle, press the two
outside buttons at the same time for one to
two seconds, and immediately release them.
138

2. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. It can usually be found
where the hanging antenna wire is attached to
the motor-head unit and may be a colored
button. Press this button. After you press this
button, you will have 30 seconds to complete
the following steps.3. Immediately return to your vehicle. Press and
hold the universal home remote button that
you would like to use to control the garage
door until the garage door moves. The
indicator light, above the selected button,
should slowly blink. You may need to hold
the button from ve to 20 seconds.
4. Immediately, within one second, release
the button when the garage door moves.
The indicator light will blink rapidly until
programming is complete.
5. Press and release the same button again.
The garage door should move, conrming
that programming is successful and complete.
To program another Rolling Code device such as
an additional garage door opener, a security
device, or home automation device, repeat
Steps 1-5, choosing a different function button
in Step 3 than what you used for the garage door
opener.
If these instructions do not work, you probably
have a Fixed Code garage door opener. Follow
the Programming instructions below for a
Fixed Code garage door opener.

5. After entering all of the switch positions,
again, rmly press and release all three
buttons at the same time. The indicator lights
will turn on.
6. Press and hold the button you would like to use
to control the garage door until the garage door
moves. The indicator light above the selected
button should slowly blink. You may need to
hold the button from ve to 55 seconds.
7. Immediately release the button when the
garage door moves. The indicator light will
blink rapidly until programming is complete.
8. Press and release the same button again.
The garage door should move, conrming
that programming is successful and complete.
To program another Fixed Code device such as an
additional garage door opener, a security device,
or home automation device, repeat Steps 1-8,
choosing a different button in Step 6 than what you
used for the garage door opener.
Using Universal Home Remote
Press and hold the appropriate button for at least
half of a second. The indicator light will come
on while the signal is being transmitted.
Reprogramming Universal Home
Remote Buttons
You can reprogram any of the three buttons by
repeating the instructions.
Erasing Universal Home Remote
Buttons
You should erase the programmed buttons when
you sell or terminate your lease.
To erase either Rolling Code or Fixed Code on
the Universal Home Remote device, do the
following:
1. Press and hold the two outside buttons at the
same time for approximately 20 seconds, until
the indicator lights, located directly above
the buttons, begin to blink rapidly.
2. Once the indicator lights begin to blink,
release both buttons. The codes from all
buttons will be erased.

{CAUTION:
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal airbag if the
system detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in
the rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 77for more on this,
including important safety information.If, after several seconds, both status indicator
lights remain on, or if there are no lights at
all, there may be a problem with the lights
or the passenger sensing system. See your
dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something may
be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger’s seat
may not have the protection of the
airbag(s). SeeAirbag Readiness Light on
page 178for more on this, including
important safety information.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in the trunk.
Also seeTires on page 351.Include an ice scraper, a small brush or broom,
a supply of windshield washer uid, a rag,
some winter outer clothing, a small shovel, a
ashlight, a red cloth, and a couple of reective
warning triangles. And, if you will be driving under
severe conditions, include a small bag of sand,
a piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly
secure these items in your vehicle.
272

If things like suitcases, tools, packages, or anything
else are put inside the vehicle, they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as
you can. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
Towing
Towing Your Vehicle
Consult your dealer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Assistance Program on
page 432.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as behind
a motorhome), see “Recreational Vehicle
Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle – such as behind a
motorhome. The two most common types of
recreational vehicle towing are known as “dinghy
towing” (towing your vehicle with all four wheels
on the ground) and “dolly towing” (towing
your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).

Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs
(454 kg). But even that can be too heavy.
It depends on how you plan to use your rig.
For example, speed, altitude, road grades, outside
temperature and how much your vehicle is used
to pull a trailer are all important. And, it can
also depend on any special equipment that
you have on your vehicle.
Ask your dealer/retailer for our trailering
information or advice. Also, seeCustomer
Assistance Offices on page 430for more
information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of your vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo you may carry in it, and
the people who will be riding in the vehicle. And if
you tow a trailer, you must add the tongue loadto the GVW because your vehicle will be carrying
that weight, too. SeeLoading Your Vehicle on
page 277for more information about your vehicle’s
maximum load capacity.
If you’re using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue (A)
should weigh 10 to 15 percent of the total loaded
trailer weight (B).
After you’ve loaded your trailer, weigh the trailer
and then the tongue, separately, to see if the
weights are proper. If they aren’t, you may be able
to get them right simply by moving some items
around in the trailer.
