CX-5 new used PCM
 

So I just had to replace the PCM in my 2016 CX-5. I used FORscan to take all the codes from the old one and re-write them into the new one. ONly problem is that the immobilizer is active and Theft detected error. Is there any software or diagnostic tools, like AUTEL or some, that could possibly be able to match the PCM to the immobilizer? Want to avoid at all cost going to my local Mazda dealer.

IMHO based on customers in the past that had similar problems and issues after using Forscan it is a poor DIY product to use. I recommend first Contact them to resolve your issue. If you try to correct it you may simply lock your computer. The other way is to take it to a shop that will do a proper pass-through of your ECU and hopefully correct the mistake that forscan created?

Forscan did not cause any error. The PCM was broken and had to be replaced. I wanted to know if it was possible to code the PCM or tge key, with forscan so the immobilizer will deactivate.
