Installed Evo on 2015 Silverado HD diesel and followed instructions, but remote start not working

0 votes
2015 Silverado 3500 Duramax. Installed everything properly and followed all directions. Even watched install video to make sure. Have all settings set to factory, expect for diesel mode and 20s crank. Doors unlock when evo module is plugged back in after decryption, but remote start does nothing. I know the module is communicating because when removed the truck goes into theft protection mode and will not start. Please help.

what is the 12 digit service number of the module?

Does the blue led flash on every lock press?


Note that if the module is not connected while the t-harness is connected to the car, you will not be able to start the car with the key. The immobilizer circuit is interupted within the harness.

The number is 001A08447041. The truck starts fine when the module is plugged in, but only when you turn the key. They remote option does nothing.


the module flashes blue continuously when unlock is pressed
