Serial Data Circuit Wiring Repairs: Notes

Special Tools

• J-38125-8  Splice Sleeve Crimping Tool
• DuraSeal splice sleeves
• A wire stripping tool

For equivalent regional tools, refer to Special Tools .

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.

GM Local Area Network (GMLAN) and Controller Area Network (CAN) serial data circuits require special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN and CAN connectors and terminals. Local Interconnect Network (LIN) serial data circuits do not require any special wiring repair procedure.
