DESCRIPTION & OPERATION

WARNINGAccidental air bag deployment is possible. Personal injury may result. Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS before working on air bag system or related components.

The Supplemental Restraint System (SRS), also known as air bag system, is designed to provide increased accident protection for driver and passenger by deploying air bags and seat belt pretensioners in a collision. The air bags deploy in about 40 milliseconds after impact sensors close. The air bag system is designed to work with the 3-point seat belt system. Seat belt pretensioners deploy in conjunction with air bags.

The main components of air bag system are driver-side and passenger-side air bag modules, side air bag modules, front and rear head air bag modules, rotary coupler (clockspring), Diagnostic Control Unit (DCU), AIR BAG warning light (SRS warning light), seat belt pretensioners and buckle switches, side impact sensors, battery disconnection unit and associated wiring harness. See COMPONENT LOCATIONS .

SERVICING

All components of the air bag system must be replaced every 15 years.

SYSTEM OPERATION CHECK

Turn ignition switch to ON position. AIR BAG warning light should illuminate for approximately 5 seconds while air bag Diagnostic Control Unit (DCU) performs self-diagnosis. AIR BAG warning light will then go off if air bag system is functioning properly. If self-diagnosis by DCU reveals that a fault exists, AIR BAG warning light will go off for one second and then turn back on. Air bag system may not operate in the event of a crash if AIR BAG warning light is on. AIR BAG warning light will also come on if low voltage condition is present, but will go off when voltage condition is corrected.

AIR BAG SAFETY PRECAUTIONS

The following precautions should be observed when working with air bag systems

  1. Disable air bag system before servicing any air bag system, steering column, seat assembly, interior trim, electrical or seat belt pretensioner components. See «DISABLING SYSTEM»(/land-rover/range-rover/l322-2002-2005/remont/airbag/#air-bag-restraint-systems__disabling-system) under DISABLING & ACTIVATING AIR BAG SYSTEM.
  2. When placing a live air bag on a bench or other surface, ensure trim cover is facing up, away from surface. If air bag is stored face down, accidental deployment will propel module through air with force sufficient to cause serious injury.
  3. DO NOT expose air bag system components to temperatures in excess of 185°F (85°C).
  4. Air bag system faults can only be diagnosed using Land Rover Test Book tester. DO NOT use electrical test equipment while attempting to service air bag system. Disconnecting or probing air bag system connectors could result in accidental deployment or system damage.
  5. If air bag module or other components have been dropped, or there are cracks, dents or other defects visible, replace with NEW parts.
  6. DO NOT attempt to measure resistance across air bag module squib connector. Accidental air bag deployment is possible which could cause personal injury.
  7. After deployment, air bag surface may contain deposits of sodium azide, a toxic substance. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. Wash hands using mild soap and water.
  8. Never allow sodium azide to mix with water, acids or heavy metals. Harmful or explosive compounds can be produced.
  9. Never attempt to incinerate or dismantle air bag or seat belt pretensioner. After deployment, components will be very hot. Allow at least 30 minutes for cooling before handling air bag modules or pretensioners.
  10. When carrying a live air bag module, make sure to face trim cover away from your body. In event of accidental deployment, this will reduce the risk of serious injury.
  11. Never install used air bag system components from another vehicle. Always use NEW parts.
  12. Always disable air bag system before performing any electrical welding or heat drying paint on vehicle.
  13. Always use NEW bolts (special Torx bolts for air bag modules) when installing any air bag system component. Ensure bolts are always tightened to correct torque.
  14. Never install electrical or electronic equipment into air bag system electrical system. Air bag harness has a Yellow outer covering.
  15. After work is complete on air bag system, ensure system is functioning properly. See «SYSTEM OPERATION CHECK»(/land-rover/range-rover/l322-2002-2005/remont/airbag/#air-bag-restraint-systems__system-operation-check) .

DISABLING SYSTEM

WARNINGAccidental air bag module deployment is possible. Personal injury may result. Never use radio key code (memory) savers when working on air bag system.

Remove key from ignition switch. Wait at least 2 minutes (to protect navigation system). Disconnect negative then positive battery cable. Wait at least 10 minutes before working on vehicle.

ACTIVATING SYSTEM

Ensure ignition switch is off and key is removed. Reconnect positive battery cable. Reconnect negative battery cable. Perform SYSTEM OPERATION CHECK . Start engine and turn steering wheel lock-to-lock. This allows the Dynamic Stability Control (DSC) system to relearn steering wheel position. Not following this procedure may result in a variety of warning lights being illuminated.

DISPOSAL PROCEDURES

Disposal of undeployed components may be a violation of federal, state, and local laws. If a vehicle is to be removed from service (scrapped), air bag system components should be deployed while installed in vehicle. See ON-VEHICLE DEPLOYMENT (SCRAPPED VEHICLES ONLY) . If this is impossible or if vehicle is being placed back into service, remove components and deploy outside vehicle. See OFF-VEHICLE DEPLOYMENT .
