Fault Finding
Serious injury can result by being too close to an airbag when it is deployed. Before making or breaking any connection in the system there should be a delay of at least 15 minutes after disconnecting the battery. When removing an airbag, especially from the steering wheel, keep your head away from the airbag face.
Because the igniters are fired electrically, a circuit tester or multimeter should not be used on any Restraint System wiring.
If the airbag warning light comes on in the fascia, owner action is to checking the fuse:
Fuse 27 in the central fuse box, 10 amp
This also provides some of the power to the ABS system, so if the ABS light illuminates as well, it is probable that this fuse is at fault.
SRS Fault Codes
Fault codes are flashed by the airbag light. A single flash with a few seconds between it is Code 1. A double flash and a pause is code 2 and so on. The codes are as follows:
1 Flash Drivers airbag failure - or open circuit to airbag (check mylar clockspring connection)
2 Flashes Passenger Airbag failure - or open circuit to airbag
3 Flashes Failure of both airbags
4 Flashes Pyrotechnic seatbelt pre-tensioner failure (Either side)
5 Flashes Drivers airbag failure - System shorted
6 Flashes Passenger airbag failure - System shorted
7 Flashes Drivers crash sensor failure
8 Flashes Passenger crash sensor failure
The most common failure is code 1. It looks as if the light is simply flashing on and off, but if this is seen the drivers airbag mylar connector should be checked for security. After disconnecting the battery and waiting at least 15 minutes the airbag can be removed from the steering wheel by undoing the Torx screws through the rear of the steering wheel lifting the airbag off and checking the multiplug on the clockspring because this can work loose. Reconnect and reinstall the airbag fully before reconnecting the battery.
