Here is my problem. My car is manual. When I leave my car, I set reservation mode correctly (lift hand brake after releasing brake) and the car is still running. Sometimes, the car shuts off early (turbo timer mode) and I cant start the car. It is giving me a code 7 for reservation mode off. The thing is, no one has gone in my car to turn off the reservation mode. This happens at least half the time. And when this happens, everytime I press a button from my pager, whether its a status query or arming/disarming or trying the autostart, you can hear the siren very faintly (I turned off the siren chirps). Any ideas? My friend installed it in alot of cars and I'm the only one having this problem. Thanks.
