Repairs to CAN bus wiring
   
t  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.
t  The colour codes of the CAN bus wiring can be gleaned from the following table:
  N97-0261
Powertrain CAN, high wireOrange/black
Convenience CAN, high wireOrange/green
Infotainment CAN, high wireOrange/violet
CAN low wire, (all)Orange/brown

t  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).
t  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.
t  There must 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.
t  Mark the area of repair with yellow insulation tape to make it easy to identify.
