Air Bag Deactivation Procedures BMW X5 E53

SPECIAL CARE DURING MECHANICAL REPAIRS

Note. When the battery is disconnected, vehicle computer and memory system may lose data. Driveability problems may exist until computer systems have completed a relearn cycle.

In some instances, it may be necessary to remove steering column or instrument panel to gain access to blower motor housing, heater assembly, evaporator assembly, or other A/C-heater system 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.

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 and repaired as soon as possible.

SERVICE PRECAUTIONS

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

1. 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»(/bmw/x5/e53-1999-2003/remont/restraints/#air-bag-deactivation-procedures__disabling-activating-air-bag-system) .
2. 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.
3. 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.
4. 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.
5. DO NOT install SRS components previously installed on another vehicle. When replacing SRS components, use only NEW, manufacturer supplied components.
6. DO NOT expose air bags or seat belt pretensioner assemblies to temperatures exceeding 200°F (93°C).
7. DO NOT spill water or oil on air bags or side impact sensors.
8. Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if equipped).
9. DO NOT attempt to disassemble air bag assembly, cable reel, or seat belt pretensioner (if equipped). Neither component has any serviceable or reusable parts.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. DO NOT allow any electrical source near inflator on back of air bag assembly or near 3-pin connector of seat belt pretensioner.
16. 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.
17. 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.

13. 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.
14. 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.

1. Obtain radio anti-theft code (if equipped) from vehicle owner and write down preset radio frequencies. To disable air bag system, ensure ignition is off and key is removed. Disconnect and shield negative battery cable.
2. To activate system, turn ignition switch to ON position. Ensure no one is inside vehicle and connect negative battery cable. Perform system operation check to ensure proper system operation. See «SYSTEM OPERATION CHECK»(/bmw/x5/e53-1999-2003/remont/restraints/#air-bag-deactivation-procedures) .

Turn ignition switch to II (driving) position. AIR BAG warning light should come on for about 3 seconds, and then go out. If light remains lit, the air bag control unit has detected a system fault.

Observe these precautions when working with air bag systems

1. Disable air bag system before servicing any air bag system component or component located in instrument panel or steering column. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/bmw/x5/e53-1999-2003/remont/restraints/#air-bag-deactivation-procedures) .
2. Because of critical operating requirements of air bag system, DO NOT attempt to service or disassemble any air bag system component. If a component is faulty it must be replaced.
3. DO NOT leave air bag components unattended. Install air bag components in vehicle immediately after they are obtained.
4. Only install NEW air bag system components supplied by manufacturer. DO NOT use components previously installed in another vehicle.
5. DO NOT use air bag or seat belt pretensioner components that have been dropped on hard surface or have mechanical damage.
6. DO NOT allow chemical cleaners, oil or grease to contact vinyl covering on air bag.
7. DO NOT place stickers or covers on steering wheel, passenger-side instrument panel or over front seat backs. Using a seat cushion, mat or pad on front passenger seat, may inhibit operation of seat occupied sensor and side air bags.
8. Disable SRS before performing electric welding on vehicle.
9. DO NOT expose air bag module or seat belt pretensioners to temperatures greater than 212°F (100°C).
10. DO NOT allow any electrical source near front or side air bag inflators or near seat belt tensioner connector.
11. NEVER use an ohmmeter or other live measuring instrument on wiring harness of undeployed air bag module or seat belt pretensioner.
12. 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.
13. 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.
