I disconected the alarm, the one that warns you when the lights are left on , Keys left in the gnition, etc. On my test drive the speedometer didn't work , and the check engine light came on. So I reconected the alarm and now everything works again , but the check light stays on . How do I reset ? Also I very much want that alarm gone , anyone know how to silence it , and still have everything work? Even the dome light woudn't work !
