Installing

  WARNING

  • Follow all safety precautions when working on pyrotechnic components. Refer to → Chapter "Safety Precautions for Pyrotechnic Components".
  • Always follow head curtain airbag installation procedure.
  • 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.

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.

- Make sure the "colored strip" is visible along the entire length. This will ensure that the head curtain airbag is NOT twisted.

  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.
