I am trying to repair a customer's remote start, EVO ALL module is doing nothing. I reprogrammed it, and it says limit reached on dcrytor. Can you please reset for me. Thank you.

Modules over 4 years cannot be flashed.

Not a problem on this car though as it's an old install that did not use dcryptor.


I can get you the old instructions but will need too know if the installation was also done with little TB-GM2 module or not.


Little note, if the TB-GM2 was used, you can reprogram the evo without issue but the TB-GM2 is a one time programming module.

Old guide found here: https://cdn02.fortin.ca/en/download/12981/12981.pdf

  • Connection 6 on Page 12 and Program 4 for installation without TB-GM2
  • Connection 6 on Page 13 and Program 7 for installation with TB-GM2


If the THAR-GM2 T-harness was used (which also included the TB-GM2), this is the guide: https://cdn02.fortin.ca/download/7361/evo-all_tharchrgm2_reva20130115.pdf
