I will give this a try, however I may have to disconnect the battery first to clear the lights, and its a bit cold out there -9*F. I will post the results.
Food for thought; The auto start does not cause the lights to come on every time that I use it, but the lights only come on if the Auto stat has been used.
Right, the remote starting, throws the lights because there is a chip in the key that is NOT being read when the car is started. This is why you shouldn't have the lights coming on with a normal key start.
Re: Is it the Autostart Sys. causing check engine light & loss of Traction Control sy
If it was a immobilizer/key issue, the vehicle would not start at all. I believe it is related to the wiring of the auto-start to the ignition harness. There are TWO starter wires that must be used, if only one is used, you will have the described problem.
Use both wires and DO NOT connect together: Starter green/black + ignition harness / Connect to alarm starter wires (this usually includes the starter kill, should be two wires and the grn/blk wire is cut). 2nd Starter black/white + ignition harness / Connect to Relay (see below) and do not cut, this wire just needs to be energized for auto-start.
Using relays is a lost art these days, use the diagram below for the second relay:
Re: Is it the Autostart Sys. causing check engine light & loss of Traction Control sy
I would look at one other thing also. I have a 2008 TT and I just finished this install last week.
All the wiring list that I was able to get my hands on say that the accessory wire is the white/green wire @ ignition harness.
There is also a blue/yellow wire @ ignition harness. This wire controls the heater blower motor. Turn on your heater - trace it back to the fuse panel and unplug it. The heater will turn off.
That white/green wire is the accessory wire and it controls the idiot lights. If your installer is tapping into this wire for the remote starter accessory (heater) connection then he is loading down the idiot light circuit and throwing alarms. Use the blue/yellow wire for your accessory connection.
Or it could be the 2nd relay. I did both, the relay and the blue/yellow wire; my trouble ended there.
It's a complicated problem. I spent days racking my brain.
Good Luck!

Thank you all for your help,
Not only does the auto-start system work like it should, I can finally enjoy driving around in a warm car without my dash being lit up and not having any traction control. "actually liked not having the tractin cotrol but the lights were very annoying"
Rather than dig into this myself when I had already paid someone to do the work, I brought some info in from the last two posts to the people who had installed the system. Although I could tell they were still convinced that it had nothing to do with the Auto start, and as they were ready to tear the system out. I asked that they at least check into from what I had read to be the two most likely solutions.
What they found was that both starter wires were connected, and that it was in fact the W/G accessory wire that was connected and causing the alarms, connecting to the BL/Y corrected the problem.
One difference that I noticed right away was that when auto started just the heater and lights came on, no radio compass or inclinometer.
Once again Thank You all for your help, hopefully someday I can return the favor.

Thanks for the info maybe I can get mine fixed now.

The FJ has two starter wires in its wiring harness. Starter1 and Starter2. Installers don't understand the uses for both and tend to twist them together. It works, but, doing this appears to bypass the neutral start switch, if you look at the schematics. You need to have them add a relay for the starter2 wire to keep it separate from starter 1 and your problems will go away. Sorry, I didn't read all the posts before writing this. An earlier post by gsgmac describes this.

Right, I brought a hard copy of the Starter Wire/Relay Diagram into the installers. However my next step is to clear out the garage and verify exactly how they have it wired.\

Once I verify the way it has been wired I will look into this as well.
Thanks.
Good luck because I have no idea what im looking at under there. If u figure it out take some pics..... and help a brotha out!
