I have a 2001 Jeep Grand Cherokee Laredo 4X4. A month ago, it had the dreaded security start/stall after 2-3 seconds as if it was being stolen. I knew it was the PCM. I took it to a mechanic who ordered the PCM, and also changed the SKIM. A new key was ordered and programmed as well. The old keys would no longer work. All parts are back on, the Jeep starts, gauges work fine, seems to run fine, except the key with the line through it light is permanently on in the dash. It comes on 15 seconds after the Jeep starts. It is solid, not flashing. Does anyone know what would cause this? Will it run like this, or will it eventually shut down again? I drove it home from the mechanic shop, which is about 30 minutes from my house with no issues. Everyone, including the mechanic is stumped about this. I'm at a loss as well, as I don't want to have to take to a dealer. I'm afraid they would just want to replace everything new again. Any ideas?
