Volkswagen Polo Service & Repair Manual: CAN Bus Wires, Repairing
| Unshielded two-strand wiring -1-
and -2- with a cross section of
0.35 mm2 or 0.5 mm2
can be used as CAN bus wiring. |
| The color coding of CAN bus wires can be found in the
following table: |
|
|
|
| CAN High wire, powertrain |
orange/black |
| CAN High wire,
Convenience |
orange/green |
| CAN High wire,
Infotainment |
orange/violet |
| CAN-Low lead (all) |
orange/brown |
| 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 Parts Catalog. |
| When repairing Bus leads, both wires must be of the same
length. When twisting together wires -1-
and -2-, the lay length of
-A- = 20 mm 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
without twisting of the wires. |
| Wrap repair points with yellow adhesive tape to mark a
performed repair. |
