stupid car wont stop beeping why?

Question

i was driving along and the stupid thing keeps beeping. it should only beep if someone sits in the back and doesnt put there seatbelt on but it does it when people arent in there. i am by far no way mechanically minded so what could it be? its only 14 months old

Answer 1

If it's still under warranty, get if fixed for free by the dealer. See what your car's owner's manual says about the belt beep conditions. You could try disconnecting the negative battery cable from the battery for a minute or so and then reconnecting it. That would "reboot" your computer and maybe reinitialize the belt detection sensors. This happens daily to thousands of cars when their batteries go dead and new batteries are installed at everyday auto parts stores. Shop manual procedures require that the battery be disconnected in order to perform many standard repairs.

Answer 2

by disconneting the battery it wont do anything to the ECM. I work in a multi-franchise dealership and havnt had anything to do with that. It could be a fault in the seat belt sensors. depending on what car it is it will only beep if the drivers seat belt is not connected. As there would always have to be some one driving the vehicle. Otherwise additional sensors would be need to tell the car if there is a person in the back seat or in the passenger seat.



Try disconnecting the battery. What a little while and reconnect. just disconnect the negetive terminal. If that doesnt fix the problem then your nearest dealer will be ablet o fix for free under warranty.

Ok, personally, I don't think that removing the negative battery cable will do it for you, but hey, I've been wrong before. My guess is a wiring or sensor problem.



Now, Grimace is wrong in what he says. Disconnecting the negative battery cable will NOT cause your ECM or PCM to lose its vital memory. The look-up tables, and reference tables, as well as fixed input tables that it uses to constantly change fuel trim and other computer controlled outputs, are saved in 1 of 3 forms usually. Those are ROM (Read Only Memory), PROM (Programmable Read Only Memory), and EEPROM (Electronically Erasable Read Only Memory). None of this information will be lost if you disconnect the negative battery cable, as bobweb told you, many simple procedures require that the negative battery cable be disconnected.



I'm not gonna say that what bobweb told you to try won't work, by all means try it before taking it in for service, just be aware that you will lose your radio presets and things like that. And there is memory that will be lost, this memory is a running record of your driving habits basically, and it is used in adaptive learning to help maximize the vehicles performance as it grow accustomed to your driving habits. So also be aware that after you re-connect it, it may act weird for 15 miles or so. It may die at a stop light, it may not drive exactly how you remember, but it needs time to relearn your typical driving habits. Good Luck.

Do not dis-connect your battery! An engines ECM(engine control module) does not "reboot"? when you do this. In fact what it may do, depending on what type of car and the type of fuel injection system it has, is wipe the computers parameter memory. Then it may need to be reset. This should be done by a trained professional.It might even effect your warranty if you start playing with things that you aren't sure about. My advice would be contact your dealer. Hope this helps.Good luck.

center college isn't that serious. in case you won't be able to get an A in a center college type, you have got some serious issues. loosen up, basically bypass with the bypass and do what you're asked of. btw, the era question. you continually could carry pads with you and shop them on your bag and it can be a sensible wager to maintain an further pair of underclothes in a bag on your locker.
