2020 Toyota 86 (PTS) starts for 2 seconds then turns off

Question

I have an automatic 2020 Toyota 86 (PTS) with an EVO-ONE installed. From my knowledge, we have all the wires tapped properly. We ran into a few issues with the immobilizer wire but I believe we got that part sorted out.

To confirm with the immobilizer wire, we cut the yellow immobilizer wire in half, tapped the light blue black and yellow red to the immobilizer wire that's connected to the ECU, and tapped the yellow green to the immobilizer wire that's connected to the other side of the car. Is this correct or should it be flipped? We're not able to aquire the immobilizer data for DCryptor but I think it's because it's not listed as supported on fortin's website, even though we go through the guide and finish with the Yellow and Red lights alternating on the EVO-ONE before attempting to use DCryptor. (Leaves us with a 'No data found' error).

Finally, we installed the antenna for the RFK411 remote and programmed it. When starting the car, it starts for about 2 seconds then turns off. Does anybody know what could be causing this issue?

Answer 1

ligh blue/black + yellow/green goes to the yellow wire on the connector side.and yellow/red to the Ecu side. You got them wrong according to your description.

Comments

Would this miswiring allow the car to start without the remote start? I'm asking because the car starts normally with the factory key. Also, would this be the reason that the car starting for 2 seconds then turning off when I try to start it with the remote start?

if your immoblizer is wrong it will either no crank at all, crank but no start or start and then shut down in2-3 seconds just like your case.

Do the proper wiring then reprogram evo-one and see whts going to happen

So just to confirm; I tapped the light blue black and yellow green to the yellow wire (IMO Wire) that's connecting to the 35 pin connector. I have the yellow red wire connected to the other side of that yellow wire (IMO Wire). The car is starting perfectly fine when I start it using the PTS button with the Evo One connected. The car starts then turns off if I attempt to remote start. Is this the correct wiring?

I also want to mention that I wasn't able to get the DCryptor data for my car but I might have been on the wrong firmware. I assumed being on the latest firmware would do the trick. Do I have to be on firmware 79 to get that data for DCryptor or is it just not compatible with the 2020 Toyota 86? I'm not sure if I need the DCryptor data as I'm using an external remote/antenna to remote start vs using the OEM remote which isn't compatible.

Easy test, disconnect red connector and attemp to start the vehicle normally, it should not start, if it does, you are not on the correct IMO wire.

 

it failing to aquiere key codes for dcryptor programming maybe due to incorrect connections or unsupported year,

I have confirmed with Fortin via phone that I have all the wiring correct. However, I've been told that there is no DCryptor data in my module. I followed all of the programming steps provided in the guide and ended with an alternating yellow/red light before disconnecting the module and trying to grab the data from DCryptor, however I get an error for no data in the module.

Is it possible that the 2019 and 2020 86 models have different key codes? Everything on those two models is exactly the same, including the immobilzer module part sold by Toyota.

If the 2020 model is not compatible, would I have still gotten the flashing yellow/red lights after doing the programming steps as well?
