Hummer H2. Manual - part 7

Never strike the air bag control module. If air bag control module is accidentally dropped, the module
MUST be replaced.

Clockspring and air bag module MUST be replaced if air bag is deployed.

On Grand Cherokee and Wrangler, ALWAYS remove and replace air bag control module and its
mounting bracket as a unit. DO NOT transfer the module to another bracket.

Fasteners, screws and bolts used to fasten air bag components have a special coating and are specifically
designed for air bag system. Use only original equipment fasteners. On Grand Cherokee, if the passenger-
side air bag module mounting screws cannot be tightened to the specified torque, replace screws with the
OEM-approved over-sized screws.

DISABLING & ACTIVATING AIR BAG SYSTEM

Disabling & Activating System

To disable system, turn ignition switch to OFF position. Disconnect negative battery cable, and isolate battery
cable end. Wait at least 2 MINUTES for system capacitor to discharge before servicing or working near air bag
system components. To activate system, reconnect negative battery cable. See SYSTEM OPERATION
CHECK .

WARNING:

Wait at least 2 MINUTES after disconnecting negative battery cable.
Servicing air bag system before 2 minutes elapse may cause accidental
air bag deployment and possible personal injury.

GENERAL INFORMATION

Air Bag Deactivation Procedures

SPECIAL CARE DURING MECHANICAL REPAIRS

In some instances, it may be necessary to remove steering column or instrument panel to gain access to
transmission control related components. Observe manufacturer service precautions when working on a vehicle
equipped with an air bag system. See appropriate manufacturer's SERVICE PRECAUTIONS.

Electrical sources should never be allowed near inflator on back of air bag module. Never probe air bag system
electrical wires with analog volt-ohmmeter or test light. Always disable air bag system before servicing vehicle.
See appropriate DISABLING & ACTIVATING AIR BAG SYSTEM procedure. Failure to do so could result in
accidental air bag deployment and possible personal injury.

If air bag system is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is
again operational. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system
from operating normally. If air bag system is not functional, park vehicle until system is repaired and functions
properly.

ACURA

SYSTEM OPERATION CHECK

When ignition is turned on, SRS indicator light should come on for about 6 seconds and then go off. If indicator
does not come on, or does not go off after about 6 seconds or comes on while driving, air bag system must be
inspected as soon as possible.

SERVICE PRECAUTIONS

Observe these precautions when working with air bag systems and seat belt pretensioners (if equipped):

WARNING:

To avoid injury from accidental air bag deployment, read and carefully
follow all SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR
BAG SYSTEM procedures.

WARNING:

Some vehicles are equipped with a passenger-side air bag ON/OFF
switch. This switch should NOT be used in place of specified vehicle air
bag system disabling and activating procedures.

WARNING:

DO NOT use any type of back-up power supply (memory saver) from
outside vehicle to avoid memory loss in memory systems (if equipped).
Back-up power supplies can provide enough voltage to deploy air bags.

NOTE:

For Acura SLX information, see ISUZU Trooper.

Disable SRS before servicing any SRS, instrument panel or steering column component. Failure to do this
could result in accidental air bag deployment, causing personal injury and/or vehicle damage. See
DISABLING & ACTIVATING AIR BAG SYSTEM .

Wait at least 3 MINUTES after disabling air bag system. A back-up power circuit capacitor (in SRS
control unit) maintains system voltage for about 3 minutes after battery is disconnected. Servicing air bag
system or seat belt pretensioners before 3 minutes may cause accidental air bag deployment and possible
personal injury.

After an accident, all SRS components, including wiring harnesses and brackets, must be inspected. If
any components are damaged or bent, they must be replaced, even if air bag did not deploy. Check
steering column, knee bolster, instrument panel steering column reinforcement plate and lower brace for
damage. DO NOT repair any component or wiring. If components or wiring are damaged or defective,
replacement is required.

Carefully inspect all SRS components before installation. DO NOT install any component that shows
signs of being dropped or improperly handled, such as dents, cracks or other deformities.

DO NOT install SRS components previously installed on another vehicle. When replacing SRS
components, use only NEW, manufacturer supplied components.

Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if
equipped).

DO NOT attempt to disassemble air bag assembly or seat belt pretensioner (if equipped). Neither
component has any serviceable or reusable parts.

A replacement air bag assembly must be stored in its original special container until used for service.
Special container must be stored in a clean, dry place, away from sources of extreme heat, sparks and
high electrical energy.

When placing a live air bag assembly on a bench or other surface, always face air bag and trim cover up,
away from surface. This will reduce motion of air bag assembly if accidentally deployed.

During installation or replacement of SRS control unit, DO NOT bump, drop or strike unit or immediate
area. SRS unit could be damaged and/or air bag deployment could occur.

After deployment, air bag assembly is very hot. Wait 30 minutes before handling. After deployment, air
bag surface may contain deposits of sodium azide and potassium nitrate, which can irritate skin. Always
wear safety glasses, rubber gloves and long-sleeved shirt during clean-up, and wash hands using mild
soap and water. Follow correct disposal procedures.

After air bag deployment, inspect all SRS wiring harnesses for heat or other damage. Replace, DO NOT
repair, any damaged harnesses. Ensure all SRS ground connections are clean and tight. Ensure SRS
wiring harnesses are installed so that they are not pinched or interfere with other components.

DO NOT allow any electrical source near front or side air bag inflators or near seat belt tensioner
connector.

When carrying a live air bag assembly, trim cover pad should be pointed away from body to minimize
injury in case of accidental air bag deployment.

If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired. DO
NOT remove any component or in any way disable system from operating normally. If SRS is not
functional, park vehicle until repairs can be made.
