Modular Wiring Routing With Corrugated Tube on Front Seat

Modular Wiring Routing with Corrugated Tube on Front Seat

Special tools, testers and auxiliary items required

• Trim removal wedge (3409)





General Information

With the introduction of modular wiring routing (Modular Light or Modular), the complete sheathing of the entire wiring harness with a fabric strap between the seat tray and the connectors to the connector station has been eliminated. A two-shell corrugated tube in which the wires are routed separately has been implemented.

Opening corrugated tube and removing individual wire

CAUTION!
Observe safety precautions for work on airbags.

- Move front seat as far back and up as possible.

- Unclip connector station cover - 1 - under front seat.





- Use Trim Removal wedge (3409) to do this.

- Disengage cover - 1 - on corrugated tube side.

- Release cable bracket - 2 - on connector station by pressing retaining tabs on both sides - arrows -.

CAUTION!
Before handling airbag units (e.g. disconnecting electrical connector), the person handling it must "discharge static electricity". This can be done by touching door striker, for example.

- Remove front seat:

• Front seat (memory seat, electric seat), removing and installing, refer to => [ Seat ] Power Front Memory Seats

- Attach seat to Fixture For Seat Repair (VAS 6136 ).

- Using Trim Removal Wedge (3409), open cable bracket - 1 -.





- Remove cable bracket - 1 - from corrugated tube - 2 -.

- See which wire routing Modular Light or Modular is present. Refer to => [ Modular Wiring Routing Versions ] Modular Wiring Routing Versions and perform the repairs.

- Remove the bolt - 1 -.





- Remove cable clip - 2 - from corrugated tube - 3 -.

- Open fabric band - 2 - in area of - arrow -.





- Open corrugated tube - 1 -.

Install individual wires and close corrugated tube

To install, perform the steps used in removal in reverse order. Observe the following when doing so:

CAUTION!
• Observe safety precautions for work on airbags.

• Before handling airbag units (e.g. disconnecting electrical connector), the person handling it must "discharge static electricity". This can be done by touching door striker, for example.

- When bundling and placing individual wires in corrugated tube, ensure wires are not twisted.

• Note installation position of two-part corrugated tube to wiring harness and position of cable bracket to corrugated tube.

- The beginning of the corrugated tube - 4 - should be placed immediately after the clip - 2 - or cable tie.





3 Wiring harness to connector station

- Ensure two-part corrugated tube - 4 - locks cleanly over entire length.

- Ensure side - arrow A - of cable bracket - 1 - connects to the last rib - arrow B - on the corrugated tube - 4 -.

- Bind transition of seat side of corrugated tube - 1 - and wiring harness - 2 - with self-adhesive fabric tape - arrow -.





- Ensure that first the pins - A arrows - on cover - 1 - engage correctly in mounts - B arrows - on connector station - 2 -.





- They can only lock in the connector station when the cover is engaged correctly.
