An unshielded two-strand wire - 1 and 2 - with a cross section of 0.35 mm 2 or 0.5 mm 2 can be used as CAN-Bus wiring.
- CAN bus wires have the following color coding:
| Powertrain CAN Bus High | orange/black |
| Comfort CAN Bus High | orange/green |
| Infotainment CAN Bus High | orange/violet |
| CAN Bus Wiring Low | orange/brown |
- During repair work, both bus wires must have the same length. When twisting the wires - 1 and 2 - together, the - A - = 20 mm routing length must be maintained.
- While doing so, no section of wire must be greater than - B - = 50 mm without twisting of wires, e.g. in area of welded connectors - arrow -.
