Front Passenger Airbag Unit With Igniter, Removing And Installing: Installing

WARNING:

Follow all safety precautions when working on pyrotechnic components. Refer to SAFETY PRECAUTIONS WHEN WORKING WITH PYROTECHNIC COMPONENTS .
Before handling pyrotechnic components (for example, connecting a connector), the person handling it must "discharge static electricity". For example, this can be done by briefly touching the door striker.
Note the allocation of the airbag to the instrument panel. Refer to the Parts Information.

Check the threaded bushings are seated correctly on the airbag pins:

-- Connect the connector -1- to the airbag igniter -arrow A-.

-- Press in the connector lock -2- -arrow B-. While doing this, the connector is pushed into the airbag igniter and locks into place.

NOTE:

Make sure the connectors are installed all the way and engage audibly.

Make sure the wires do not get caught.

WARNING:

The ignition must be on when connecting the battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. There must not be anyone in the vehicle interior when connecting the battery.

-- Connect the battery ground cable with the ignition switched on. Refer to BATTERY, DISCONNECTING AND CONNECTING .

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of injuries due to unintentional deployments when the ignition is switched on.

If the ignition is not switched on after the battery is reconnected - >>indicator lamps in the instrument cluster do not light up<< - the ignition (key/button) may only be switched on when the driver seat is positioned all the way back.

NOTE:

If the Airbag Indicator Lamp -K75- indicates a fault after installing, check the DTC memory, erase it and check it again using the Vehicle Diagnostic Tester.

Information for installation: for example, tightening specifications, replacing body parts. Refer to OVERVIEW - FRONT PASSENGER AIRBAG and OVERVIEW - INSTRUMENT PANEL .
