Ethernet Cable Repairs

The GM Global Ethernet cable repair strategy uses the replacement of cables to repair vehicle issues. These cables can be found in the Electric Parts Catalogue (EPC) by first identifying the main harness that contains the needed cable and then looking for the cable references in the graphic

Ethernet Cables come without the connector. Ethernet Cables come with the terminals crimped on the cable. Also, these cables are a universal length to service as many applications as possible with the fewest part numbers. Because of this, the cable received maybe slightly (<500mm) longer then the original cable contained within the factor harness. Extra length of cable should be coiled up and secured.

Cable Repair Procedure 

NOTE:
• Do not splice wires or perform your own crimps.
• Service harness kits will be released per vehicle and the kit will contain a length for each leg/peripheral device.
• The lengths are designed to allow for some extra slack but loop-backs and hard turns or pinches are not desirable.
• Twisted pairs are supplied with terminals already crimped.
• If an Ethernet wiring repair kit is not available, the entire harness must be replaced.
1. Identify the faulty/damaged Ethernet cable.
2. Identify the type of cable and utilize the Electric Part Catalogue to obtain the correct parts.
3. Disconnect the faulty/damaged cable connectors at both ends.
4. Remove the terminals from both connectors using the proper terminal removal tool.
5. Overlay the properly twisted pair of wires provided in Ethernet Wiring Repair kit.
NOTE:

To avoid permanent damage, do not pinch the cable or bend it tighter than a 2 inch (5 centimeter) radius.

6. Neatly route and secure Ethernet wiring to existing harness taking up the extra length without pinching or bunching up the wires.
7. Use felt tape/foam to prevent the cable from rattling, as needed.
NOTE:

If connectors are damaged, see the connector end view for the affected connector to obtain the Service connector part number.

8. Insert terminals into connectors.
9. Reconnect the connectors to the components.
10. Cut any replaced wires and/or connectors off of the old cable, as close to the harness breakout as possible, without damaging the harness.
