Removing
WARNING
Follow all safety precautions when working on pyrotechnic components. Refer to → Chapter "Safety Precautions for Pyrotechnic Components".
- Disconnect the battery ground cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
- Equipment versions without the side charge air cooler: remove the front section of the front wheel housing liner. Refer to → Body Exterior; Rep. Gr.66; Wheel Housing Liner; Front Wheel Housing Liner, Removing and Installing.
- Equipment versions with side charge air cooler: remove the bumper cover. Refer to → Body Exterior; Rep. Gr.63; Front Bumper; Bumper Cover, Removing and Installing.
- Remove the bolt -1- and the front airbag crash sensor -2- from the headlamp mount.
WARNING
Before handling pyrotechnic components (for example, disconnecting the connector), the person handling it must "discharge static electricity". This can be done by briefly touching the door striker pin, for example.
- Disconnect the connector -3-.
- To do this pull out the connector lock -2-, push down -arrow-, and disconnect the connector -1- on the crash sensor.
Installing
WARNING
- Follow all safety precautions when working on pyrotechnic components. Refer to → Chapter "Safety Precautions for Pyrotechnic Components".
- Before handling pyrotechnic components (for example, connecting the connector), the person handling it must "discharge static electricity". This can be done by briefly touching the door striker pin, for example.
- Connect the connector -1- to the crash sensor until it clicks into place in direction of -arrow-.
- Push in the connector lock -2- to secure the connector.
Installation is performed in reverse order of removal, while noting 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.
WARNING
Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of unintentional deployments when the battery is connected.
- The ignition must be on when connecting the battery.
- For personal safety when connecting the battery, stay out of the deployment area of the airbag and maintain a distance from the seat belt tensioners/seat belts.
- Make sure that there are no other people inside the vehicle at the time when the battery is connected.
- Connect the battery ground cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
Note
If the Airbag Indicator Lamp -K75- indicates a fault, check the Diagnostic Trouble Code (DTC) memory, erase it and check it again using the Vehicle Diagnostic Tester.
Installation notes, for example tightening specifications, replacing components. Refer to → Chapter "Component Location Overview - Airbag Crash Sensors".
