Airbag Unit With Igniter, Removing And Installing: Installing

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:

NOTE:

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

Make sure the wires are not pinched.

-- Connect the spiral spring connector with the airbag connector coupling on the return spring with slip ring.

-- Press in the connector to secure it in the pockets on the steering wheel.

-- Position the driver side airbag in the steering wheel and press on until it audibly engages.

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.

-- Check and erase the airbag control module DTC memory because faults can be stored from when the connectors are disconnected. Use the Vehicle Diagnostic Tester.
