EVO-ONE DCRYPTOR Programming Issue

Question

I am finally installing my EVO-ONE with THAR-TOY-13 on my 2021 Toyota RAV4 Hybrid, after four years since I purchased it.

While following the programming procedure, I am stopped at step 4, because the expected result is not achieved.

1) Press and hold the programming button: Connect the 4-PIN Data-link harness (Black connector). - The BLUE, RED, YELLOW and BLUE & RED LEDs will alternatively illuminate. - CHECK

2) Release the programming button when the LED is BLUE. - CHECK

3) Insert the required remaining connectors. - CHECK

4) Do not press the brake pedal. Press the Push-to-Start button twice to turn on the ignition. - Wait for the BLUE LED to flash rapidly and constantly. - PROBLEM: After pressing the start button two times, all of the LEDs turn off and the blue LED does not flash at all

I have already reset the device by disabling protection and then following resetting procedure in car (release button on red LED and then press again and hold until LEDs flash in sequence)  - However still the problem presists.

Can this problem be fixed? - Thanks

Looking at the histroy of this unit, it was already programmed and dcrypted once in dec of 2024 and again in jan of 2025 in this vehicle.

If the blue light goes out with ignition on but does not flash you would want to verify the can hi and can lo wires. If using a t-harness disconnect and inspect all pins and connectors, then re seat them ensuring all connectors fully bottom out.

Best regards.

Thank you. I will verify those connections and will report back.
