CAN-Bus Wiring, Repairing

CAN-Bus Wiring, Repairing 

NOTE: 

-

Observe general notes for repairs on the vehicle electrical system.

-

Observe the notes on wiring harness and connector repairs including identifying repair locations.

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 mm without twisting of wires, e.g. in area of welded connectors -arrow-.
