GMLAN Wire Repair
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Refer to Wiring Repairs in the service information connector end views or the vehicle schematics in order to determine the correct wire size for the circuit you are repairing. You must obtain this information in order to ensure circuit integrity.
If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gauge size (0.5 mm2 , 0.8 mm2 , 1.0 mm2 etc.). Use the DuraSeal splice sleeves and EL-38125-10 tool. For wiring repair, refer to Wire to Wire Repair .
