Removing wiring for backrest







ATTENTION:
Danger of injury and material damage if airbag units are not handled correctly. Always observe the safety regulations for handling airbag units.
- The airbag unit must always be stowed so that the airbag opening faces upwards.
- If removed for an extended period, the airbag unit must be kept in a locked place.
- Remove ignition key. Disconnect battery. Route or isolate ground strap so that all contact with a ground carrier (e.g. body, seat frame) is avoided.
- After the battery is disconnected, always wait for 1 minute before disconnecting the airbag plugs.







1. Release the plugs on the height -1- and cambering adjustment motor -2- of the lumbar support -Arrow A- and disconnect -Arrow B-..

NOTE: Disconnect the plug from the backrest adjustment motor in an axial direction only. Otherwise the retaining lugs can break off and a secure plug lock cannot be guaranteed.

2. Pull off plug from the backrest adjustment motor -Arrow C-.
3. Unclip wiring harness using a disassembly tool, universal NR.21-Arrows-.







4. Push inner edge of protective cover inwards -Arrow A- and pull protective cover down and out -Arrow B-.







5. Cut tie-wrap -C- and remove protective cover.
6. Remove line upwards -Arrow D-. Make sure that the two plugs are not damaged.

Installing wiring for backrest
1. Guide side airbag wiring harness through the backrest frame -Arrow A-. Make sure that the two plugs are not damaged when you do this.







2. Clip wiring harness onto the backrest frame -Arrows B-.

NOTE: Ensure that the tie-wrap is installed correctly as it can impact on the backrest frame and hinder installation of the protective cover.

3. Fit protective cover on wiring harness and fasten it with a commercially available tie-wrap -Arrow A-. Push protective cover upwards -Arrow B- and fasten it to the backrest frame.







4. Push in plug on backrest adjustment motor -Arrow A- until it is felt to engage.







5. Insert the plugs on the height -1- and cambering adjustment motor -2- of the lumbar support -Arrow B- until the locking mechanisms are felt to engage -Arrow C-.
