Flash Limit Reached

0 votes
I messed around with my unit trying to increase the run time limit and messed everything up. Can you please give me the proper Firmware for the remote and bypass? Also, if I enable the diesel option, will it run my truck for 30 minutes instead of 15? It was -7 F here in wyoming and 15 minutes doesnt do it and i forget about restarting it most mornings.


Thank you,



Unit 002B04152594

2018 Toy Tundra SR5 H key.

The flash limits are reset.

Enabling diesel mode will double the run time.

For firmwares, just use whatever is being suggested in the flash link.


Please make sure to reset the bypass if you are starting over from scratch.

Thank you, I will give this a try.
So I flashed the unit as directed, reset the bypass and installed back into truck and programmed. I get the blue light when the lock button is pressed on my key and I'll get the red light after three lock presses but nothing after that.

any ideas?
OK, Spoke to Amir and went through the whole process again (Master/Bypass reset and reprogramming). Same thing. Red light, no crank, even with foot brake output disabled. Should I just buy a new unit?
No crank would point more towards the T-harness or Starter connection (if not using a t-harness) then the module.
