Repair wire CAN bus

As wire CAN bus uses two-wire line 1 and 2 with a cross section of 0.35 mm ² or 0.5 ^mm 2.

Color-coded wire CAN bus found in the following table

Wire tires CAN-High, privodoranzhevy / black;

Wire tires CAN-High, komfortoranzhevy / green;

Wire tires CAN-High, Infotainment orange / purple;

Wire CAN-Low (all) orange / brown.

CAN bus wire repairs must be carried out using both the maintenance of a suitable cross-section wires and twisted wires "green / yellow" or "white / yellow" according to parts catalog.

When repairing tires have two wires have the same length. When twisting the wires 1 and 2, the length of the coil should be at A = 20 mm.

It does not have to be formed piece of wire, for example, in welded contacts is longer than B = 50 mm without twisting the wires.

Wrap the renovated section of the yellow tape to signify that this spot was repaired.

Replacing the antenna wire

To repair the wire antenna developed a new concept of repair. As spare parts, instead of the wire antenna, as a whole, are now being offered the connecting wires of different lengths, as well as a variety of adapter cables.

general description

The antenna wires are not repairable. If repairs are needed, they should be replaced by the connection cables and adapter cables offered as original spare parts.

These original spare parts are suitable for the replacement of all antenna wires of any section.

Connector housing for antenna cables are available as spare parts in only one color, but can be used to replace the antenna plug of any color.

Replacing the separate antenna connectors in case of repair are not available.

These wires can be used in all VW models with antenna wires of any section.

All connecting cables and adapter cable are suitable for any received and transmitted signals.

This repair concept can also be used for testing and additional equipment.

Overview of mounting the antenna wire

Example: damaged antenna wire from the radio to the antenna. For repair, the following wires:

1 - adapter cable to connect to the radio. Length about 30 cm.

2 - connecting cable supplied in various lengths.

3 - adapter cable to connect the antenna. Length about 30 cm.

Installation of the new antenna wire

Unplug the antenna wire from the damaged instrument.

Locate the damaged antenna wire laid in the car and measure the total length of the damaged antenna wire.

The total length of the antenna wire is made up of the length of the necessary adapter cables 1 and 3, as well as the length of the bonding wire 2 (Fig. 7.127).

Subtract from the measured total length of the antenna wire 60 cm to determine the length of the necessary connecting cables 2.

Acquire the necessary adapter cables 13 and connecting wires 2 correct length according to the catalog of spare parts.

Cut the damaged antenna wire connectors.

The balance of the damaged antenna wire remains in the vehicle.

Connect the adapter cables 1 and 3 to the devices of the car.

Lay and fix the connecting cable 2 right next to the "serial" cable.

Connect the wire with the adapter cable.

Spend check.

Repair wire up to 0.35 m m ²

When repairing wires with a cross section 0.35 mm ² must be necessarily Press on new terminals Crimp tool for contacts JPT, or crimping tool (without head) VAS 1978/12, established a replaceable head for contacts JPT - VAS 1978 / 91. Because of the small values of current in these conductors in micro - and millidiapazone incorrectly crimped contacts lead to a transition resistance and cause malfunction or failure of any system. Most often these contacts occur in the following devices:

- Lambda probe;

- Speed sensor;

- Air mass meter.

Through the use of crimping pliers for contacts JPT or crimping pliers (without head) with the replaceable head for contacts JPT ensure proper connection between the crimp, wire and wire seal (Seal). Use the tool only for its intended purpose.

Pressure testing of the new tip seal with wire

Insert a removable head for JPT contacts in crimping pliers (base handles).

Push the wire seal on the repair wire (Fig. 7.128).

Open crimping pliers and insert the end of the repair wire into the hole for stripping (Fig. 7.129).

Fully tighten the clamp.

Again, open clamp and remove the stripped wire.

Slide the seal wire toward the stripped end, that it ends flush with the insulated wire.

Insert the new tip into the crimp jaws crimp pliers.

Insert the stripped end of the wire in the crimp seal aligned tip to the end adjoined to mark ?�Wire-Stop?� (Fig. 7.130).

Pressure test cap, wire and seal completely squeezing the crimping pliers.

Again, open clamp and remove the finished tip.

Correctly executed crimping different net wires and crimp seal at the tip, and on its reverse side there chasing, which means that the pressure testing has been carried out professionally and with the proper tool (Fig. 7.131).

Broken wire in one place

Place repairs one crimp sleeve

Release the wire, which must be repaired (about 20 cm on both sides of the repair).

If necessary, remove the coil harness folding knife.

Vyrezhte damaged section of wire stripping pliers.

Strip 6-7 mm of insulation from the ends of the wire with pliers for stripping (Fig. 7.132).

Push crimp sleeve to both the stripped end of the wire and crimp it with the crimping tool (Fig. 7.133).

Wire insulation pressure test is impossible.

After crimping crimp sleeve need to sit down, to prevent moisture ingress into.

Fit the extension of the industrial hair dryer, 220 V / 50 Hz.

Heat crimp sleeve hairdryer in the longitudinal direction from the middle to the edges until it is fully compressed and the glue on the end of the projection (Fig. 7.134).
