Air Bag Control Module: 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
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.


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.
