Check whether an additional ground cable must be routed in the vehicle:

CAUTION: If a passenger airbag is replaced, an additional ground cable must be routed in the vehicle in some cases.

- Check whether a ground cable is routed on the passenger airbag housing:
- With a passenger airbag with ground line - 1 -, the wiring harness - 2 - is a three-conductor harness, and in addition, another cable - 3 - is secured on the threaded pins - 4 -.
- With a passenger airbag without ground line - 5 -, the wiring harness - 6 - is a two-connector harness and no additional cable is secured on the threaded pins - 7 -.







On a passenger airbag without ground cable, route an additional ground cable in vehicle:
- Secure end of ground line with screw - 1 - on right side of passenger airbag.
- Route ground line correctly to right side of passenger footwell.

NOTE: Lengthen the ground cable as needed with suitable instruments from the Wiring Harness Repair Kit VAS 1978 or the Wiring Harness Repair Kit VAS 1978A.
