GMLAN Wiring Repairs: Notes

Tools Required 

J-38125  Terminal Repair Kit. See Special Tools .

The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals.

The tool kit J-38125  contains the following items in order to repair the GMLAN wiring:

• DuraSeal splice sleeves
• A wire stripping tool
• J 38125-8 Crimping Tool (GM P/N 12085115)
• J 38125-5 Ultra Torch Special Tool (GM P/N 12085116)

The DuraSeal splice sleeves have the following 2 critical features:

• A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside.
• A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits.

The J-38125  also serves as a generic terminal repair kit. See Special Tools . The kit contains the following items:

• A large sampling of common electrical terminals
• The correct tools in order to attach the terminals to the wires
• The correct tools in order to remove the terminals from the connectors
