    Replaced Theft Deturrent module, Car thinks it's stolen

    Title says it. I know that the standard method is to take the car to a dealer, but I'm wondering if there is an independent mechanic with a Tech II scanner that cab do the work? The intent being to save some cash. Or do I have other options? I'm in the los Angeles Area, any helpfull suggestions will be greatly apreciated.

    Thanx

    I'm pretty sure there is a relearn procedure you can do with just your key and key fob. I'll try to remember to look for it in the FSM after work today.

    I know there's the "30 minute relearn" that you can do if you replace the ECU/ECM - I just had to do that a couple weeks ago. But I think the TDM relearn is a different procedure.

    Thanks.Yea, I know About the 30 min relearn procedure (there's also a 10min procedure) but according to the service manual they both require a Tech II to initiate the procedure. Of course the manual assumes you have A Tech II handy. I'm hoping for a work around and extra pairs of eyes helps.

    I forgot to look it up yesterday, so I don't know what the relearn process is for the TDM. I know the whole point of the 30-min relearn is that you don't have a Tech2 to use. It requires nothing other than a key that was previously programmed to the car. I've done it on 2 or 3 occasions, no Tech2, just me in my driveway or garage.

    Re: Replaced Theft Deturrent module, Car thinks it's stolen

    So I finally remembered to look up the procedures. The 10-min relearn does require the Tech2. Both the 10-min and 30-min relearns say that if you're replacing the TDM, you have to perform the procedure to setup a new TDM (which also requires a Tech2) before doing the relearn.

    Sounds like you're screwed. Even if you find an independent mechanic with a Tech2 I'm guessing you won't save much money - it'll probably be 1hr labor either way.

    Hello propninja,

    I am sorry you are still experiencing issues with your service theft deterrent system module. I know you mentioned wanting to go around working with a dealer, however due to the issue still occurring, if you are willing to work with a dealer please let us know. We can be contacted via private message.

    Sincerely,

    Laura M.
