from electrical noise.

When placing a live air bag on a bench or other surface, ensure pad top surface is facing up, away from
bench surface. This will reduce motion of module if it is accidentally deployed.

Because of critical operating requirements of air bag system, DO NOT attempt to service air bag module
(s), clockspring, wiring harness or SRS Control Module (SRSCM). Air bag system repairs are only made
by replacement of faulty components. DO NOT use any component previously installed on another
vehicle. Use NEW components only.

If any air bag system component has been dropped, or there are cracks, dents or other defects in case,
bracket or connector, replace with NEW component.

DO NOT attempt to measure resistance across air bag module squib connector. Accidental air bag
deployment is possible which could cause personal injury.

After deployment, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always
wear safety glasses, rubber gloves and long-sleeved shirt during clean-up, and wash hands using mild
soap and water.

SRS control module must be replaced after deploying air bags one time. After deployment of an air bag,
replace clockspring with a new one.

Before using electric welding, disconnect air bag Yellow connectors located at base of steering column,
near multifunction switch connector.

After SRS repairs are completed, ensure system is functioning properly. See SYSTEM OPERATING
CHECK .

DISABLING & ACTIVATING AIR BAG SYSTEM

To disable SRS, turn ignition switch to LOCK position. Disconnect and isolate negative battery cable. Wait at
least 30 SECONDS before servicing SRS. To activate SRS, reconnect negative battery cable. Perform
SYSTEM OPERATING CHECK .

INFINITI

SYSTEM OPERATION CHECK

On I30 and QX4, turn ignition ON and verify that AIR BAG indicator light comes on for about 7 seconds, then
goes off. On Q45, turn ignition ON and verify that AIR BAG indicator light and SEAT BELT indicator light
and chime come on for about 7 seconds, then go off.

On all models, if AIR BAG indicator light does not come on or after about 7 seconds does not go out or begins
to flash, a SRS malfunction has been detected. On Q45, if SEAT BELT indicator light does not come on or
stays on longer than 7 seconds with seat belt fastened, a seat belt pretensioner malfunction has been detected.

SERVICE PRECAUTIONS

Observe these precautions when working with air bag systems:

Disable SRS system before servicing any SRS component, instrument panel components, steering column
components or seat belt pretensioners (if equipped). Failure to do this could result in accidental activation

of SRS and causing personal injury and/or vehicle damage. See DISABLING & ACTIVATING AIR
BAG SYSTEM .

Wait at least 3 MINUTES after disabling SRS before servicing vehicle. System maintains SRS system
voltage for about 3 minutes. Servicing air bag system or seat belt pretensioners (if equipped) before 3
minutes could result in accidental SRS activation, causing personal injury and/or vehicle damage.

After repairs, ensure AIR BAG indicator light is operating properly and no system faults are indicated.
See SYSTEM OPERATION CHECK .

Always wear safety glasses when servicing or handling an air bag system components.

Air bag modules and seat belt pretensioners (if equipped) must be stored their original special containers
until installation. They must be stored in a clean, dry place, away from sources of extreme heat, sparks or
high electrical energy.

Always place SRS components on a clean flat surface. When placing a live air bag module on a bench,
always face air bag and trim cover up, away from surface. This will reduce motion of module if
accidentally activated.

After deployment, air bag surface may contain deposits of sodium hydroxide, 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.

At no time should any electrical source be allowed near inflator on back of air bag module.

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

DO NOT probe a wire through insulator; this will damage wire and eventually cause failure due to
corrosion.

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

DISABLING & ACTIVATING AIR BAG SYSTEM

Disabling Air Bag System

Record preset radio station frequencies. Turn ignition off. Disconnect and shield negative battery cable and then
positive battery cable. Wait at least 3 MINUTES.

Activating Air Bag System

Ensure ignition is off. Connect positive battery cable and then negative battery cable. Ensure AIR BAG and
SEAT BELT indicator lights are operating properly and no system faults are indicated. See SYSTEM
OPERATION CHECK .

GENERAL INFORMATION Air Bag Deactivation Procedures

Turn ignition ON and verify that AIR BAG indicator light flashes 7 times, then turns off. AIR BAG indicator
light should not come on during vehicle operation. If AIR BAG indicator light does not function as described,
service air bag system.

SERVICE PRECAUTIONS

Observe these precautions when working with air bag system:

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

Wait at least 15 SECONDS (10 MINUTES on Hombre) after disabling SRS before servicing vehicle.
System maintains SRS system voltage for time specified. Servicing SRS system before time has elapsed
could result in accidental air bag deployment, and possible personal injury and/or vehicle damage.

After repairs, ensure AIR BAG indicator light is operating properly and no system faults are indicated.
See SYSTEM OPERATION CHECK .

Always wear safety glasses when servicing or handling an air bag.

Air bag modules must be stored in original special container until used for service. They must be stored in
a clean, dry place, away from sources of extreme heat, sparks or high electrical energy.

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

Any SRS component dropped from a height greater than 39 inches must be replaced.

DO NOT subject SRS components to temperatures greater than 150°F (66°C).

At no time should any electrical source be allowed near inflator on back of air bag module.

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

DO NOT attempt to disassemble any SRS component. SRS components are serviced as a complete unit
and contain no serviceable components.

DO NOT probe a wire through insulator; this will damage wire and eventually cause failure due to
corrosion.

DISABLING & ACTIVATING AIR BAG SYSTEM
