The airbag in your vehicle is an important safety device, and the airbag module ensures the proper functioning of your vehicle's air bag. If this module is not functioning properly, your airbag may not deploy during a crash. When there is a malfunction, your airbag module warning light will illuminate on your vehicle's dash. You will need to have the airbag assembly checked out by a qualified mechanic, but once that is done, you can reset the warning light and airbag module unit. If you've never done this type of job before, it should only take you 5 minutes.
Open the bonnet and loosen the retaining nut on the negative cable wire cable clamp using a socket wrench.
Slide the cable clamp off the negative battery terminal.
Wait 3 to 5 seconds and reconnect the battery terminal. Tighten the retaining nut using a socket wrench. Once the power is restored, the airbag module should be reset.
Verify that the module has been reset by turning the ignition key to the "II" position and checking to make sure that the airbag light does not illuminate.
