Rearming the Airbags
WARNING: Carry out the following procedure to rearm and check the airbags after completing all work on the vehicles electrical systems.
Note: The vehicle battery must be disconnected within 12 seconds of switching off the ignition to avoid the alarm siren sounding.
- Disconnect the battery ground lead. Allow a minimum of one minute delay for the back-up power supply to discharge.
- Remove the drivers side airbag simulator and replace it with the drivers airbag module. Secure the airbag module with the two captive torx screws.
- Remove the passengers side airbag simulator and replace it with the passenger side airbag module. Secure the module with four nuts and washers. Close the passenger side airbag door.
- Reconnect the battery ground.
- Switch on the ignition and check for correct indications from the SRS/AIRBAG warning light. The SRS/AIRBAG lamp should come on after a brief delay and remain on for approximately six seconds during the airbag system self check. The lamp will extinguish upon satisfactory completion of the self check, or will flash a diagnostic code if an airbag system fault is detected. Continuous illumination of the warning lamp may indicate a seatbelt pretensioner fault
Note: Reset the clock and window ECUs on completion.
WARNINGS AND CAUTIONS:
WARNINGS:
Disarm the airbags by disconnecting the battery ground (black) lead, waiting one minute and then removing the airbag modules before servicing of any airbag or steering column component.
After disconnecting the battery ground lead, allow a minimum of one minute delay for the back-up power supply to discharge before servicing the airbag system.
The system components are non-serviceable, if faults are suspected, change components for new items only.
Failure to observe the above procedures may result in accidental deployment of the airbags.
Always wear safety glasses when working on airbag equipped vehicles.
Personnel carrying an airbag module must ensure that the module and trim cover are pointing away from the body. When positioning on a bench or work surface, ensure that the airbag module and trim cover face upwards to limit motion on accidental deployment.
Always wear gloves when handling deployed airbag modules. Deposits of sodium hydroxide may be present on the module surface. If sodium hydroxide contacts any area of the skin, wash the affected area immediately with mild soap and water. Dispose of the deployed airbag using the correct procedures referred to in this section.
Caution:
When scrapping vehicles, ensure that the airbags have been deployed (see Scrapping Vehicles with Live Airbags).
If a component has been renewed and the fault does not clear, refit the original item and repeat the diagnostic procedure.
After servicing, repeat the diagnostic procedures to ensure correct system operation.
Renew the airbag module if the surrounding trim panels are damaged. Do not attempt to repaint trim covers as paint may damage cover material.
