2009 Pontiac G3 Wave 1.6L (E LXV) 4-spd (AW81-40LE) — 3G2TX55E29L126522
No Crank / No Start

Hello everybody. I would like to turn off the immo this Pontiac G3 2009. It's a PK3+ system. Immobilizer module is not working and is no more available from GM. Seems to be not an easy job. I calles Ac Delco to get a VCI number but they can't help me. I tried to do modification with HP Tuners to remove this feature from PCM but without success. Is it possible to do that with some device or do I have to open the module and do a eeprom job? Any help will be appeciated?

Daniel, It appears that you are replacing the PCM on this vehicle. The donor could be from a global A and causing you grief. TunerCat is one software that comes to mind to remove immobilizer. I think maybe EFI live is another that can do it. You may want to try another donor you know is the same year, make and model. It may just take to your application without having to turn off the…

I'm not a specialist in this area but I am unaware of any Aveo/G3 (T200) that is Global A.

I agree. If I can use the Tech2 scantool on this vehicle as I do, I don't believe it is part of the Global A family.

If the immobilizer module is damaged you can replace it with any used pk3+ module and do a reset on it with most decent aftermarket tools or sps. Its not something that fails often so should be no issue with a used one. Immo-off is not really needed or a good solution for you imo. Just as easy (or easier) to fix the problem.

An update on my problem. Today, I went to an auto parts recycler, friend of mine, and brought with me a PCM, a VTD module, a key cylinder and the key corresponding to the cylinder. All used parts from the same vehicle (same year, same engine). But, as I expected, the vehicle does not start. And no codes in PCM, VTD or any other module. There must be another module on the network that analyzes…

The PCM and TDM need to make hand shakes between one another and the keys need to be programmed into them. If your vehicle is not starting with the donor stuff you put in then you either have a problem with the used ecm or TDM or maybe it came out of a standard vehicle and your trying to put it into a automatic (which its now looking for a clutch pedal input to allow it to start) or if the theft…

Hello again everyone. I would like to tell you how, finally, I managed to start this vehicle. I had to replace the PCM with a new part from GM. Strangely, the security module has resumed communicating with the PCM. I contacted GM Techline, temporarily installed the Tis2Web software, programmed the PCM, keys and resynchronized the PCM and TDM. What a pleasure to hear this engine running. Thank…
