Repairing CAN-Bus wires
- Use an unshielded two-strand wire - 1 - and - 2 - with a cross-section of 0.35 mm 2 or 0.5 mm 2 as a CAN-Bus wire.
- Refer to the following table for color coding of CAN-Bus wires:
| Powertrain CAN-Bus, High | orange/black |
| Convenience CAN-Bus, High | orange/green |
| Infotainment CAN-Bus, High | orange/violet |
| CAN-Bus, Low (all) | orange/brown |
CAUTION:
- Perform wiring harness repairs only with yellow wires from VAS 1978 Wiring Harness Repair Kit. Mark repair locations with yellow tape.
- Both bus wires must be the same length. When both wires - 1 - and - 2 - are twisted, length - A - = 20 mm must be maintained for the twist.
- No part of the bus wiring in the vicinity of heat-shrink sleeves - arrow - , may be greater than - B - = 50 mm without the wires being twisted.
- 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 Replacement parts catalog (ETKA).
- Wrap repair points with yellow adhesive tape to signify a repair.
