An unshielded two-wire line -1- and -2- with a cross section of 0.35 mm2 or 0.5 mm2 is used for CAN bus wiring.

The colour codes of the CAN bus wiring can be gleaned from the following table:
Repairs to CAN bus wiring
Powertrain CAN, high wire Orange/black
Convenience CAN, high wire Orange/green
Infotainment CAN, high wire Orange/violet
CAN low wire, (all) Orange/brown
Repairs to CAN bus wiring can be carried out either with sections of repair wiring with the correct cross section or with entwined wires “green/yellow” or “white/yellow” from the electronic parts catalogue (ETKA) → Electronic parts catalogue (ETKA). When repairs are performed, both bus wires must have the same length. When twisting the wires -1- and -2- together, the length of each complete twist must be A = 20 mm. There may not be any section of wiring, for example in the vicinity of crimp connectors -arrow-, longer than B = 50 mm with the wires not twisted. Mark the area of repair with yellow insulation tape to make it easy to identify.
