Open the hood of the GMC and loosen the retaining nut on the negative battery cable clamp.
Slide the cable clamp off the negative battery terminal.
Wait 15 minutes, then reconnect the cable clamp.
Start the engine and run it for 5 to 10 minutes to allow your GMC vehicle to relearn its idle procedure.
