2007 CHEVROLET AVALANCHE ECU

The passenger sensing system is designed to turn
off the right front passenger’s airbag if:
The right front passenger seat is unoccupied
The system determines that an infant is
present in a rear-facing infant seat
The system determines that a small child is
present in a forward-facing child restraint
The system determines that a small child is
present in a booster seat
A right front passenger takes his/her weight off
of the seat for a period of time
The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s airbag, the off indicator will light
and stay lit to remind you that the airbag is off.If a child restraint has been installed and the
on indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall
the child restraint following the child restraint
manufacturer’s directions and refer toSecuring
a Child Restraint in the Right Front Seat Position
on page 68.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion.
If this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint.
If the on indicator is still lit, secure the child
in the child restraint in a rear seat position in
the vehicle and check with your dealer.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep
the airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height, front
end or side sheet metal, they may keep the
airbag system from working properly. Also,
the airbag system may not work properly if you
relocate any of the airbag sensors. If you have
any questions about this, you should contact
Customer Assistance before you modify your
vehicle. The phone numbers and addresses
for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure
on page 582.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, rollover sensor
module, steering wheel, instrument panel,
overhead console, ceiling headliner, ceiling
and pillar garnish trim, roof-mounted rollover
airbag modules, or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.
