How to program 2010 F150 with Key Decryptor

Question

I'm using the key decryptor method to program evo-all CAN BUS module on a 2010 F150. Following the directions, I hold prog button, plug in data, release on solid red, then continue to plug in remaining connectors.

Once connected, I press prog once, the red LED turns off then on. Here's where it doesn't work correctly..

When I put key in ignition, and turn to run/on, the yellow LED turns on but the red does not turn off as stated in directions.

I do have the rx and tx wired as described in guide light blue/blk to violet/gray(rx) and light blue to orange/yellow(tx)

 

Firm: 71.47

Answer 1

if you have a flashlink updater, please try to flash down to 71.28 first and re-try programming, if that does not work, flash down to 4.18 and redo programming, If the firmwares above do not work then there will be an issue with your RX TX connections
