Air Bag(s) Arming and Disarming: Service Precautions
Service warnings
Personal safety
Failure to follow all warnings, cautions, notices and procedures could result in personal injury or death.
Power supply deactivation
Air bag-SRS diagnostic unit contains a backup power supply. Before disconnecting air bag-SRS components, turn ignition switch to LOCK, disconnect
battery (negative terminal first), and wait 10 minutes for backup power supply to discharge.
Failure to follow this procedure could cause air bag modules to deploy during service procedures, which may cause serious injury.
Safety equipment
Always wear safety glasses when handling air bag modules.
Always wear rubber gloves when handling deployed or damaged air bag modules.
Air bag surface may be contaminated with small amounts of sodium hydroxide (NaOH). Prevent contact of air bag module with liquids, combustibles,
and flammable materials. Immediately wash contaminated hands and skin areas with mild soap and water, flush eyes with water if exposed to
by-products. Failure to follow these instructions could result in chemical burns and personal injury.
Wiring and electrical components
Never service wiring or electrical components when any air bag is connected. When a procedure directs use of a multimeter to probe pins of a connector,
insert probes into back of connector where possible. If you must probe front face (terminal side), be certain to use a probe whose tip will not damage
terminals when it is inserted.
Component disassembly
Do not disassemble any air bag-SRS components. Disassembly can render system inoperative, which may result in serious injury or death in event of an
accident. Never attempt to disassemble or repair air bag modules. Any attempt to adapt, re-use, or install an air bag module or its components in another
vehicle may result in serious injury or death to vehicle occupants in event of an accident.
Air bag diagnostic unit (ADU)
Do not connect ADU connector unless ADU is securely installed. Shock of installation or pinching wiring harness between module and its mounting
points can cause air bags to deploy, which may cause serious injury.
Air bag module inspection
Do not probe or inspect air bag modules or any of their connectors with an ohmmeter. Inspecting air bag module with an ohmmeter, which supplies
current, can cause air bags to deploy, resulting in serious injury.
Air bag module connector
Do not cut or otherwise remove the air bag module connector. Connector contains a safety shunt which, if disabled, could cause an unintended
deployment. This may cause severe personal injury or death.
Air bag module handling
A live (undeployed) air bag may accidently deploy during handling. When carrying a live air bag module, point plastic trim cover away from your body
to lessen chance of injury in case of accidental deployment. Never carry module by its wiring or connectors.
Securing modules
Always place live air bag modules face up (plastic trim side up) to lessen motion of the module in case of accidental deployment. Keep the area clear of
parts, tools and other debris. Never place items on or above the trim cover of a live air bag module. In case of accidental deployment, such items may
cause serious injury or death
Live air bag module storage
Live air bag modules contain solid flammable material. Store in a cool, dry, secure area. Do not expose them to cut, drill, braze, solder or weld an air bag
