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-SRSCM diagnostic module 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.

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.


Supplemental Restraint System Control Module (SRSCM)
Do not connect SRSCM connector unless SRSCM 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.
