Repairing Can Bus Wires

NOTE:

Observe general notes for repairs on the vehicle electrical system. Refer to VEHICLE ELECTRICAL SYSTEM, GENERAL REPAIR INFORMATION .

Unshielded, twisted two-wire lines -1 and 2- with a cross section of 0.35 mm ² or 0.5 mm² can be used as CAN-Bus wiring.

Repairs on CAN-Bus wires can be performed with repair wire with matching cross section and also with twisted wires "green/yellow" or "white/yellow" from the Parts Information.
When repairing CAN bus wires, both wires must be same length. When twisting together wires -1 and 2-, the lay length of A = 20 mm (0.78 in.) must be observed.
While doing this, no section of the wire, for example, in area of crimp connectors -arrow-, may be greater than B = 50 mm (1.96 in.) without twisting of the wires.
Wrap repair points with yellow adhesive tape to mark a performed repair.
