The color coding of CAN bus lines can be found in the following table:

Powertrain CAN high wire	orange/black
Comfort CAN high wire	orange/green

Repairs on CAN bus lines can be performed using repair wire with matching cross section, and also using twisted wires "green/yellow" and "white/yellow" .
When repairing CAN bus lines, both wires must be same length. When twisting together wires -1- and -2-, the lay length of A = 20 mm must be observed.
