Is it the Autostart Sys. causing check engine light & loss of Traction Control sys?

Here is a brief summary of my Auto Start experience over the last 3 or 4 months, any advice would be greatly appreciated.

• Prestige 2-way Auto Start “professionally” Installed.
• Later the same day as the install the Check engine light and all traction control lights came on once key was put in the ignition, traction control was disabled.
• After a few hours and several restarts with just the key in ignition the lights cleared and everything was normal.
• The next day the lights came when I used the auto start system and key put in ignition.
• I brought the vehicle back to the place where the Auto Start was installed, they reset the unit by disconnecting the -12v battery lead for five minutes. And said that the computer just needed to recognize the new hardware. “a common problem with Toyota”
• No lights came on when auto started until the next day, and I once again had the same problem.
• At this point the company that installed the auto start system was convinced that the lights were not related to the auto start system.
• Due to the fact that I never had this issue until the day the system was installed, I did not agree, so I drove the vehicle for three weeks without using the auto start and no lights never came on and the traction control system worked fine.
• Three weeks later I auto started the vehicle and vuall’a the lights came on and the traction control was disabled.
• I called the Auto start company and reported my findings,
• So I took the vehicle back again and the installers looked over all of the wiring and replaced the security module. They were then able to auto start the vehicle several times with no trouble. Once I picked up the vehicle got it home and auto started it later that evening the lights came back on. Called the Auto Start company and let them know that the problem was not fixed. They told me that my exhaust stinks and there must be something wrong with my vehicle, or it was because of the lift I installed way before I ever had the auto start installed or had any problems.
• So I took the vehicle into Toyota who found a trouble code for the “Neutral Safety Switch”. They ordered the part.
• A week later they went to change out the switch and discovered it did not correct the problem so they put the old switch back in and gave me a slip of paper stating that the light were coming on due to the aftermarket auto start system.
• So I called the Auto Start people faxed them the Toyota document and asked that they remove the entire system. They were outraged, called Toyota and argued that they could not put the blame on them if they couldn’t see where the problem was originating from. And rather than remove the system the want to see if a “Compu-star” system module will make a difference.
• Despite the fact that I am very tired of dealing with this non-sense and am doubting that it will help, I agreed an scheduled an appointment to see what happens. 1/6/09

Has anyone ever come across a similar problem, or have any suggestions of things that I can check to avoid bringing the vehicle back to these guys? Is there any thing about an ’08 Trail Teams rig that could be different from an ’07 FJ that the auto start company claims to have installed several of these units on without any problems?

Thanks for reading
