Disconnect the negative cable from the battery and isolate it to prevent accidental contact with the terminal. Remove the instrument panel top cover and the glovebox. Take out the screws securing the airbag to the instrument panel, including those along the top of the passenger airbag cover and the two lower airbag cover screws. Remove the three securing nuts holding the back of the airbag assembly to the instrument panel support structure. Lift the airbag module, squeeze the red locking tab, compress the lock, and unplug the 4-pin module electrical connector before removing the airbag module. Installation is the reverse of removal, ensuring the red locking tab is locked after attaching the connector, and tighten the screws and nuts securely. From the driver's side, turn the ignition switch to the Off position and then to the On position, checking that the instrument cluster AIRBAG lamp illuminates for six to eight seconds before going out, which indicates the airbag system is functioning properly. If the lamp fails to light, blinks, or stays on, there is a malfunction in the airbag system, and a dealer service department or qualified repair shop should diagnose the vehicle.
