I installed a FT-DC LC on my Chevy Cobalt 2007, My car has after market locks and is just a base model with an auto trans. Use the Pk3 LC GM 2 harness. I bought the USB programmer and programed it.
Programed it to the instructions and all I get is 1 flash then 3 flashes from the head light. That tells me it the tach programming. When programming the tach, I get 2 green flashes and after that it start flashing green and only way to stop it is disconnect the DC3 from power. I had a t-11 remote and it wouldn't program to the DC3 and I sent it back. Now all I have is the LTE Drone unit. I did make a video of me programing it to the car.
Any help before I take it to a shop. Thanks
I know its not the DC3 because I bought another one and tried it. Going to install it in my wife's car later on.

i guess im not fully understanding. When you program the tach you get 2 green flashes (means it programed digitally) then you just get continuous green flashes on the dc3 all the time? Couple questions, auto or manual transmission and did you cut the green/white lopped wire on the side before programming?

Auto trans and yes I did cut the wire. After the 2 green flashes, it stops and then starts flashing green. I even bought the 2WT11R-SS remote, it's no programming to the system. This is my 2nd remote. Remote only said disarm.

thats a odd issue. I have not seen that one before. did several cobalts at xmas time and didn't have any issues with them and the dc3. Is this the older version with the yellow and black box or the new black/blue box? Id plug it back into the computer and make sure the update for the antenna has been done

I might end up taking it to a shop. I thought the first one was bad and so I bought another. Both DC3s are doing the same thing. I going to use the spare one in my wife's car. I used the USB hub and programed it. Tried LC and HC and still doing the same thing.
