Just wondering when the update for the 2020 Sierra will be available ? Is it the same that the 2019 ? It looks the same for the wiring but not sure for the firmware.

Thanks

There is a slight change in 2020. Firmware is in testing phase and will be out soon.

Hi! I saw on the installing guide of the 2019 Sierra 1500 , that now it's written 2019-2020 and that 70.40 firmware should be used, but on the Flashlink Manager only the 70.39 is available for now... mistake or just because the firmware is not ready yet?
 

Thanks, just to give an answer to my customer

Just tested it today on my customer 2020 Sierra 1500 Standard-Key, and it won't go over programming, I've reset the module a couple time, flash the firmware to 70.40, went in truck to program and after the 5 flash on yellow led and static yellow, turn the key On and it won't do anything else than yellow/red flashing 1x per second .

Evo-All is brand new , I've made like 5-6 firmware flash because of testing, could the module flash limit be reset please ? Since it's only been done for testing

 

Thanks

Also I forgot to mention, engine of the truck is the I4 2.7L Turbo gasoline engine, could it be different from the classic 4.8L or 5.3L V8 ? Thanks again

Plug in only red connector, start the car for a couple of seconds, shut it down, leave the red connector connected then program the module.

Already done that according to your troubleshooting guide, same situation occur...
commenté Juil 14, 2020 par Jerome Thomassin (2,450 points)
Once the car is shut down, leave the red connector connected to the module, wait 20-30sec, then attempt programming.
