CAN-Bus Wiring Repairs, General Information 

-

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

-

CAN-Bus wiring uses the following color codes:

CAN-High-wire, Powertrain

orange/black

CAN-High wire, comfort

orange/green

CAN-High wire, infotainment

orange/violet

CAN-Low wire (all)

orange/brown

-

Exclusive use is to be made of yellow wires for wiring harness repairs. Mark repair places with yellow tape.

-

When repairing Bus wires, both wires must be same length. When twisting together wires - 1 - and - 2 -, the routing length of - A - = 20 mm must
be maintained.

-

While doing this, no section of wire, e.g. in area of welded connectors - arrow -, may be greater than - B - = 50 mm without twisting of the wires.
