ECU GMC CANYON 2007 Service Manual

To activate the content theft-deterrent system,
do the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry
transmitter is pressed, but a door is open, the horn
will chirp six times. Press the lock button again,
within three seconds, and the doors will lock. Close
the open door and the system will be activated.
If a locked door is not opened using the remote
keyless entry transmitter, or by OnStar
®, the
pre-alarm will go off. If the engine is not started or
unlock not pressed within 10 seconds, the front
turn signal lamps will ash for two minutes, and the
horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system will not
activate if you lock the doors with a key, the manual
door lock, or power door lock switch. The system
can only be activated using the remote keyless
entry transmitter, or by OnStar
®. SeeOnStar®
System on page 146for additional information.You should also remember that you can start your
vehicle with the correct ignition key if the alarm has
been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the remote keyless
entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, you can turn
off the alarm by pressing unlock on the remote
keyless entry transmitter. The alarm will not stop if
you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system
by locking the doors with the remote keyless
entry transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or
start the engine.

If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses and Circuit Breakers on page 426.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.
Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or
the ignition lock cylinder is tampered with, the fuel
system is disabled and the vehicle will not start.
During normal operation, the security light will turn
off approximately ve seconds after the engine
is started. SeeSecurity Light on page 192.If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.
If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your Passlock
®
system is not working properly and must be
serviced by your dealer. Your vehicle is not
protected by Passlock
®at this time. See your
dealer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 462.

The mirrors can be manually folded inward to
prevent damage when going through an automatic
car wash. To fold, push the mirror toward the
vehicle. To return the mirror to its original position,
push outward. Be sure to return both mirrors to
the unfolded position before driving.
Outside Convex Mirror
Your passenger’s outside rearview mirror is
convex. A convex mirror’s surface is curved so
you can see more from the driver’s seat.
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply into
the right lane, you could hit a vehicle
on your right. Check your inside mirror
or glance over your shoulder before
changing lanes.
OnStar®System
OnStar®uses several innovative technologies and
live advisors to provide you with a wide range
of safety, security, information, and convenience
services. If your airbags deploy, the system is
designed to make an automatic call to OnStar
®
Emergency advisors who can request emergency
services be sent to your location. If you lock
your keys in the vehicle, call OnStar
®at
1-888-4-ONSTAR and they can send a signal
to unlock your doors. If you need roadside
assistance, press the OnStar
®button and they
can contact Roadside Service for you.

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.There is a label on your sun visor that says,
“Never put a rear-facing child seat in the front.”
This is because the risk to the rear-facing child is
so great if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
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.

Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher
than the seatbacks can be thrown
forward during a sudden stop. You
or your passengers could be injured.
Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by ying objects.
Secure the cargo properly.
CAUTION: (Continued)
CAUTION: (Continued)

Heavy loads on the roof raise the
vehicle’s center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
Keep cargo in the cargo area as far
forward and low as possible.
There are some important things to remember
about how to load your vehicle.
The heaviest things should be on the load
oor and forward of the rear axle. Put
heavier items as far forward as you can.
Be sure the load is secured properly, so
driving on the off-road terrain does not
toss things around.
You will nd other important information in this
manual. SeeLoading Your Vehicle on page 286
andTires on page 369.

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 your vehicle.
Also seeTires on page 369.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.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the tires
and the road, you can have a very slippery
situation. You will have a lot less traction, or grip,
and will need to be very careful.
