Hello. I have a Chevrolet Express 2002 model, (Norway) ST68870, 1GCFG25F521162802, which I can't start. One day I was driving it, turned it off and left it for about 1 hour. When I got back, the car would not open with the remote key fob and ofcourse not start. So I suspect there is some issues with the Passlock system, and since it's different from the US models and such it becomes a little bit difficult to bypass as far as I know. The remote key fob blinks with a small red light when I push either lock or unlock.
From what I have read online, there are only 2 ways to get the car started on export vehicles, No. 1 is to use the remote key fob that turns off the Passlock system for 2 minutes, or No. 2 is to use the "override code" which is a 5 digit code that comes with the car when it is new, something I do not have.
I have tried to find the 5 digit override code with a Tech2 and TIS2000 software, but with no luck, I think I do not have the right security access on TIS2000. There is no fault codes when i check with the Tech2.

The key fob runs on 433.92 MHz and not the usual US type 315(?) MHz, I have not yet found a new remote key fob for my car with that MHz. The receiver (Blue box 16242815) or theft deterrent was laying "loose" on top of the engine cover, might be broken? I dont know how to check if it is broken or not, or if I get a new one, will it need to be programmed or something like that, or is it only "plug and play"?




Please help.

Have the same problem and the same box...
Did you find the sollution?

Doge

Yes, I changed the PCM I got from a 98 model (mine is 2002), and this does not have the imobilizer thing. Some people may also help you with the one you got to downgrade it to a older version like mine now. I have removed the blue box, so the remote control wont work. Car starts and works fine now.
Hope this helps, and good luck

Thanks alot ☺️
My is a 1998 model but have immobilizer, where did you buy/program the PCM?

Doge

Oh. I got mine from a friend who was getting rid of the car.. And I only know of a local shop who can fix the programing, but I think they want the whole car at their place to fix it..

Hi Robin,

I also own a 2002 Tahoe which is an Euro model. I am also in Norway. I have no problems yet, but would like to be prepared. So you are saying that I cannot use any PCM for example purchased thru Rock Auto. It has to be an Euro PCM? Been trying to get a spare remote, not have any luck with than.

Thanks,

Brian

Any replacement PCM you buy requires some programming to use in the vehicle. A used one may work without anything done to it, so long as it is from a van with the same engine and transmission combo.
