SOURCE: Hello accent 2004 with anti theft system battery flat anti theft

Have you verified this system is running the battery down? The system you describe is called the Remote Keyless Entry System (Electronic Time/Alarm & Control System - ETACS Module). It cannot be 'disconnected' without disabling other systems (intermittent wipers, Chime bell, Door Warning, Dimming Off Room Lamp, Seat Belt indicator, remote power door lock/unlock system, etc.)

SOURCE: lowbeams headlamp won,t work on 2005 buick

Start simple. Investigate your fuses, since it is unlikely, but not unheard of, for both low beams to fail simultaneously.

Do you know where your fuses are?

2005 rendezvous. Changed serpenntine belt and replaced leaking front seal when took it down off the jacks it will not start. Turns over but acts like fuel has been shut off. Is this an anti theft or fuel...


Sounds like maybe you knocked the Crank Sensor loose, or possibly the injector plug harness up top near the alternator. Check all of your wiring really good in the vacinity that you were working in and around. If your anti theft light isnt flashing you in the face with the key on and engine off it isnt a fuel or theft issue. The anti theft system disables the fuel to the injectors, if you raised the car too high it can trigger the anti theft and it must be reset, but unlikely. Check all of your connections.
