2002 Tahoe wont run

[Steve Berg]

Hi. Strange problem with my Tahoe. Came home from a 60 miles drive tonight and the car was fine. Parked outside the garage and emptied some shopping before trying to start the car and pull inside. Car then just ignited and stopped within a short while. Central locking won't work from the remote and no interior lights works. I looked for fuses and can't find any blown and tried with both keys and remotes. Also disconnected the negative terminal from the battery for like 10 minutes but stil have the same problem. Anyone out there who had the same problem and can point me in a direction here? I have no clue where to look now. Tomorrow I will try to scann the car to see if I have any information that way but I stopped now as it is freezing cold here in northern Norway and I needed a brake.

Thanks and regards,
Steve

For starters - no pun intended - have that battery load-tested and see what the printout tells you. So it will crank and fire up but doesn't run very long?

Start then stops almost immediately is a stereotypical symptom of PASSLOCK security system engaging. Is the security light flashing on the cluster?

Not flashing but comes on when ignition is on and then nalternate with the charge lamp.

Battery is good. The strange thing is that powerlock and interior lights also stopped working at the same time. No lights in the doors when i open the car eiher.

might need a battery or battery cables, the battery could have enough power for some lamps but not enough amps to make it start or operate other things that take some power. just something to consider (maybe put it on a charger if you can or have it checked to verify), check the positive cable, take it off and wire brush it and the battery terminal, clean ground connections reconnect and try again.
if it starts and then dies a second later, that is a separate issue.

Scan show problems with security system but i cant delete dtc. Is there a way i can delete the security system

With ignition off it stays on permanent. Do you know which part of the passlock normally fails first?

What specific DTC is being set? If more than one, please post all.
