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

Replace the connector for the Front Passenger Airbag Release Valve Igniter -N491- after an airbag has deployed. Refer to WIRING HARNESSES AND CONNECTORS, REPAIRING .

WARNING:

Risk of injury due to involuntary deployment.

Pay attention to the safety precautions when working with 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.

Install in reverse order of removal and note the following:

-- Connect the connector -1- to the airbag igniter in direction of -arrow A-.

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

NOTE:

Make sure the connectors are pushed in all the way and that they engage audibly.

Make sure the wires are not pinched.

WARNING:

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

The ignition must be on when connecting the battery.
Make sure that no one is inside the vehicle at the time when the battery is connected.

-- 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.
