GENERAL INFORMATION

Air Bag Deactivation Procedures - Acura

SPECIAL CARE DURING MECHANICAL REPAIRS

WARNING:

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

WARNING:

Do not use electrical test equipment on the Yellow SRS wires and connectors in the steering column, console, dashboard, and floor. You could unintentionally set off the air bag(s) or seat belt tensioners, which could cause injury to you or others. While troubleshooting or repairing other systems, be careful not to damage SRS wiring or components. Damage could make the air bag(s) or seat belt tensioners inoperative, which could lead to driver's or passenger's injury or death if the car were in a severe frontal collision.

WARNING:

Some vehicles are equipped with a passenger's 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.

CAUTION:

Ensure ignition if off, then disconnect battery. Wait at least 3 minutes before working on system. The capacitors in the system control unit store enough current to deploy air bags even after battery is disconnected. Waiting 3 minutes allows current to dissipate.

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. See COMPUTER RELEARN PROCEDURES - ACURA article in GENERAL INFORMATION.

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 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 procedure under DISABLING & ACTIVATING AIR BAG SYSTEM . 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 a few seconds and then go off. If indicator does not come on, or does not go off after a few seconds or illuminates 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):

• 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 appropriate procedure under 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.
• Radio has a coded theft protection circuit. Before disconnecting battery cables get radio activation code from vehicle owner.
• Avoid direct exposure of SRS unit or wiring harnesses to heat guns, welding or spraying equipment when painting or doing body work.
• DO NOT attempt to modify, splice or repair SRS wiring harnesses. Ensure SRS wiring harnesses are installed so that they are not pinched or interfering with other components.
• 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.
• Whenever air bags have been activated, replace seat belt pretensioners (if equipped) and SRS unit.
• 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.
• DO NOT expose air bags or seat belt pretensioner assemblies to temperatures exceeding 212°F (100°C).
• DO NOT spill water or oil on air bags or side impact sensors.
• Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if equipped).
• DO NOT position yourself in front of air bag during removal, inspection or replacement.
• DO NOT attempt to disassemble air bag assembly, cable reel, 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, 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 inflator on back of air bag assembly or near 3-pin connector of seat belt pretensioner.
• During SRS component installation or replacement, be careful to not bump area around SRS unit, front impact sensors or side impact sensor using an impact wrench, hammer, etc. Air bags could accidentally deploy causing damage or injury.
• 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.
