CAN-Bus Wiring, Repairing

NOTE:
- Observe general notes for repairs on the vehicle electrical system.
- Observe the notes on wiring harness and connector repairs.






An unshielded two-strand wire -1 and 2- with a cross section of 0.35 sq.mm or 0.5 sq.mm can be used as CAN-Bus wiring.

- CAN bus wires have the following color coding:

Powertrain CAN Bus High orange/black
Comfort CAN Bus High orange/green
Infotainment CAN Bus High orange/violet
CAN Bus Wiring Low orange/brown

- During repair work, both bus wires must have the same length. When twisting the wires -1 and 2- together, the -A- = 20 mm routing length must be maintained.
- While doing so, no section of wire must be greater than -B- = 50 mmwithout twisting of wires, e.g. in area of welded connectors -arrow-.
