Volkswagen Golf Service & Repair Manual: Repairs to CAN bus wiring
| |
An unshielded two-wire line -1-
and -2- with a cross section of
0.35 mm2 or 0.5 mm2
is used for CAN bus wiring. |
| The colour codes of the CAN bus wiring can be gleaned from
the following table: |
|
|
|
| Powertrain CAN, high wire |
Orange/black |
| Convenience CAN, high
wire |
Orange/green |
| Infotainment CAN, high
wire |
Orange/violet |
| CAN low wire, (all) |
Orange/brown |
| Repairs to CAN bus wiring can be carried out either with
sections of repair wiring with the correct cross section or with
entwined wires “green/yellow” or “white/yellow” from the
electronic parts catalogue (ETKA)
→ Electronic parts catalogue (ETKA). |
| When repairs are performed, both bus wires must have the
same length. When twisting the wires -1-
and -2- together, the length of
each complete twist must be A = 20 mm. |
| There may not be any section of wiring, for example in the
vicinity of crimp connectors -arrow-,
longer than B = 50 mm with the wires not twisted. |
| Mark the area of repair with yellow insulation tape to make
it easy to identify. |
