Compustar Remote Start and DVD bypass?

After my brother-in-law had a bunch of problems getting my compustar alarm/remote start put in, I took it to have a "pro" to do it. The alarm seems to work but not the remote start. I follow the steps to put the car in reservation mode I pull the key out and car is still running, I shut the door, car shuts off and the remote sings a little song. When I go to remote start it, it chirps a couple of times and I think blinks twice and then blinks 7 times which tells me the car is not in reservation mode from what the book says. I called the installer and he said it had to do with my dvd head unit and the fact that I bypassed it so it plays dvd when the car is moving (or so he thinks) and he said if not that something in the car is making the reservation mode turn off. All I did with the dvd was take the wire from the head unit and grounded it instead of connecting to the parking brake. This should have nothing to do with it or does it? I have tried turning the power off on the player which should make it work but no luck. The installer claims he got it to work a couple of times but didn't play with it. He was basically telling me to figure it out or pay me more money to fix it. I got this big song and dance on the phone when they told me it was done saying how much of a pain and it was bad but we got it to work. I also tried shutting the ac off too. Any ideas on what this could be? I have a scion tc if that helps and it's a kenwood DDX 8017. Thanks!

Chances are the dome light is triggering the door trigger sensor and this tells the Compustar that the door opened prior to remote start giving you this error.Jeff

I was hoping to here from you, I see you on a lot of replies and you always seem to help. Anyway, so you think if the dome light was off or disconnected, it might work? It makes sense cuz in the scion tc the dome light fades slowly off. I'll try to turn it off first and wait to see what you say about disconnecting it. THANKS!

I turned both my dome lights to the off setting, turned off A/C, and turned off radio. It still doesn't start. I have nothing else electronic in my car that was added besides the alarm. I don't even have my phone charger in. I don't know if this helps but I had to have an immobilizer bypass (556uw) put in to bypass my immobilizer. The car comes with a red light that flashes when my key comes out showing the immobilizer is active. It still comes on, could this be the problem?

Sit in the car and see if the dome light triggers prior to remote starting. The installer might not have tapped into the correct door trigger wire and might have used the dome light trigger wire. If it does not trigger the dome light you might have to bring it back to the dealer and ask them to test the door trigger wire prior to remote start to see if this wire is getting voltage.Jeff

I'm thinking now it might be the door trigger. I'm gonna check and see in the morning. Me and my brother-in-law had all the right connections (after two weekends) until we ran into the 556uw transponder for the key. Now it seems that the alarm goes off for no reason. I turned the sensor down from 6 to 4 and it worked for about a day and now I had to shut it off. It's not like it goes off when a loud car goes by but just randomly. This alarm has been nothing but a pain. I would never buy this alarm again. I only got it cuz it was supposed to be one of the best (and best for remote alarm) but a lot of people didn't know about it like the viper and clifford. I thought that would be good and harder to stop.

The Compustar system is very good and is only as good as the installation. Not poking at the quality of the installation, but 99.9 % of the time when there's a problem with falsing systems, it's because of wrong trigger wires, incorrectly setting sensors, not knowing about the vehicle's interaction with the system or just plain not knowing about the systems capabilites. Just to add, just because you brought it to a "pro", even "pro's" have their problems with systems if they are not familiar witht he system or with the vehicle. Please post the make, model & year of the vehicle as well in your next response. I have installed many of the 2 way RS/security systems into many different vehicles and have had 2 issues with the vehicles doing what yours is doing and that's because I went according to some wiring datasheets that told me to grab the door triggers at a certain place and this ended up being the same wire that trigger's the dome light. One in particular was the Sunfire where you have to wire in diodes to isolate the door switch from the BCM otherwise you will always get a feedback signal and the RS thinks that the door opened.Jeff

It's a 2005 Scion tC. I got the cars wiring info from this link http://directechs.com/directwire/wire_body.asp?action=select&yr=5681&product=Remote%20Start# and that's what we (me and my bother-in-law) used when we tried it. I even printed out a copy including the "notes" and when I got the car back you could tell it wasn't even looked at, so I assumed they had one of there own but maybe not. These guys are autherized dealers/installers so they should know the alarm. Is it wrong to expect them to fix it for free?
