GMLAN and CAN Connector Terminal Repair
WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
A terminated lead can be used to replace damaged connector terminals for both GMLAN and CAN systems. When making a connector terminal repair on a GMLAN high speed system or CAN with twisted pair wires, do not untwist the wires more than necessary to make the repair.
If the individual terminals are damaged on any GMLAN or CAN connection, use the appropriate connector repair procedure in order to repair the terminal. Refer to Connector Repairs for the appropriate connector repair procedure.
