Air Bag(s) Arming and Disarming: Service Precautions
On-vehicle service procedure
Service warnings
Personal safety
Failure to follow all warnings, cautions, notices and procedures could result in personal injury or death.
Power supply deactivation
Airbag-SRS diagnostic unit contains a backup power supply. Before disconnecting airbag-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 airbag modules to deploy during service procedures, which may cause serious injury.
Safety equipment
-
Always wear safety glasses when handling airbag modules.
-
Always wear rubber gloves when handling deployed or damaged airbag modules.
Airbag surface may be contaminated with small amounts of sodium hydroxide(NaOH). Prevent contact of airbag 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 airbag and pretensioner 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 airbag-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 airbag modules. Any attempt to adapt, re-use, or install an airbag module or its components in another
vehicle may result in serious injury or death to vehicle occupants in event of an accident.
Airbag 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 airbags and pretensioner to deploy, which may cause serious injury.
Airbag module inspection
Do not probe or inspect airbag modules or any of their connectors with an ohmmeter. Inspecting airbag module with an ohmmeter, which supplies
current, can cause airbags to deploy, resulting in serious injury.
Airbag module connector
Do not cut or otherwise remove the airbag module connector. Connector contains a safety shunt which, if disabled, could cause an unintended
deployment. This may cause severe personal injury or death.
Airbag module handling
A live(undeployed) airbag may accidentally deploy during handling. When carrying a live airbag 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 airbag 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 airbag module. In case of accidental deployment, such items may
cause serious injury or death.
Live airbag module storage
Live airbag modules contain solid flammable material. Store in a cool, dry, secure area. Do not expose them to open flame or temperatures in excess of
