Astrostart Module Replacement Programing

Hi New here. I have searched and can not find my answer. I have a 2004 GMC Yukon XL 1500. It has had the Astrostart 3100 alarm/start system since day 1. Long story short the dealer fried the 3100 module. I replaced it with a 5200. I believe it will work. All the wiring was a direct plug and play. I have programed the remotes. Doors unlock and lock. I can not get the auto start to work. I get a constant flash of the led when trying to program the tach learning. Any help would be helpful. Thank you in advance

Update I am now getting a 4 flash code when start fails. No wiring changes. If the wiring is fine. When I set 1,5,6,7 it clicks 4 times,seconds then goes to a continual flash.

Ok how do you hav it wired and I can walk you through programming, I am assuming that when you say 5200 you mean ether athe 5224 or the 5225 one mile remote starter. Both should have a e-xrt on the brain. I. Will also need to now what bypass you are using. My guess for the year it is most likely a one for the passlock2 and another for the door locks through data. Please note that I would like to know the wiring and how it hooked up because you should have two outputs to ignition and two to accessory for that vehicle, so you don’t have transmission problems Code 4 is not tach reading

It was professionally installed in 2004. It had a 3100 module. I brought the vehicle in for service work. When it returned the autostart did not work. I took it to where it was installed and they told me the module was fried. I confirmed this. I replaced the module with a 5200. Programmed the remotes. No start. Did the 1,5,6,7 key in warmed up brake sequence. The module seems to accept the code but flashes continuously. When trying to start code 4 flashes no start. Everything has worked for 14 years no wiring changes. The alarm, door locks and start. Now doors look, alarm works, no start.

The new module will still need to be programmed to do outputs correctly they are not plug and play for vehicles, I just need to know what wire colors of the remote start are hooked to the wire colors of the vehicle and I can help, and just so you know the led will flash all the time with engine running, it is letting you know it is seeing a tach, it should not be really fast or really slow, I am going to guess that they used a negative out put for the park lights and the park lights wire reprogrammed for the ignition so if this wire is not right it will not feed the ignition wire during remote start and will not start

Ok after looking up the manual for the brain, the park light is not programmable like later models so some programmable out put will have to be use, so I will need to know what wire S go where to help you program it to this vehicle.

I will take pictures tomorrow and post them. Thank you

I will pm you and send email, might make it easier.

I have the wiring for you vehicle I just need the verification from remote start to the vehicle, match the remote colors to what vehicle colors they are attatted to, just need to know what wires they used for what, and I would guess they most likely got the tach from behind the instrument cluster it was easier then under the hood.
