Modular Wiring Routing With Corrugated Tubing on Front Seat

Modular Wiring Routing with Corrugated Tubing on Front Seat

Special tools, testers and auxiliary items required







- Trim removal wedge 3409

General information

With the introduction of modular wiring routing, 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 tubing in which the wires are routed separately has been implemented.
Opening corrugated tubing 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 tubing side.







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

1 - Wiring harness
3 - Corrugated tubing, two-shelled

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

- Remove front seat.
- Attach seat to Fixture For Seat Repair VAS 6136.

CAUTION:
- Observe safety precautions for work on airbags.
- Before handling airbag units (e.g. disconnecting electrical connector), the person handling it must "electrostatically discharge". This can be done by touching door striker, for example.

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

NOTE: Note installation position of two-part corrugated tubing to wiring harness and position of cable bracket to corrugated tubing.







- The beginning of the corrugated tubing - 4 - should be placed immediately after the clip - 2 - or cable tie.
- 3 - Wiring harness to connector station
- Ensure two-part corrugated tubing - 4 - locks cleanly over entire length.
- Ensure side - arrow A - of cable bracket - 1 - connects to the last rib - arrow B - on the corrugated tubing - 4 -.







- Bind transition of seat side of corrugated tubing - 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.
