Question about Hyundai Motor 2004 Sonata

1 Answer

Weird electrical glitches

For about a year the locks on my 2004 sonota lock by themselves when I close the door or while driving they lock and unlock randomly (it's not a feature). Now the brake lights and headlights seem to get stuck on. They are daytime running lights but sometimes they stay on when I turn the car off or the brake lights stay on even when not on the brakes and even when I turn the car off. This also causes the cruise control not to work.
What could be causing all this? Is it linked?

    I have close to the same problem, My brake lights stay on all the time when car is running. My cruise control also stopped working. I replaced the brake light switch it had no effect.

It sounds like the sonata computer might be corrupted. Do you use mp3, or ipod to play music through your stereo and or do you play burned music? It's my belief that the computer can become corrupted from maleware code. Also do you know if there was any command start installed or removed? Command starters are notorious for causing computer glitches and malfunctions in the locking mechanisms.

Why does my nissan maxima door locks unlock themselves and there is a clickng sound


It sounds like there is an electrical fault with the Remote locking circuit. When you lock the vehicle, without seeing the schematic electrical drawing, there is a relay that will operate to lock the doors. This applies power to the small motors installed within the doors, that operate the locks open/close (Lock/Unlock). Generally there is an electrical componet that by passes the relay once the doors are locked so it doesnt burn out, e.g Capacior. With that in mind, if this component is shorting out, power will be applied and/ or released from the holding circuit which in turn, will operate the vehicles locking mechanism.
Best way forward
1. If you have a Gregorys manual, available from Super Cheap Auto for under $50, it will have the Electrical circuit drawing for the Door locks, if it's standard fit to the path finder. You will be able then, with the use of a Multi meter, to check out where power is getting to or not (12V dc).

2. If not give the Auto electrician $50 to fix.

As the Nissian is 24 years old, I would be looking for a electrical component failure.

I hope this helps you out mate,
Stevie C.

What is the default anti-theft lock code for a 2000 Toyota Camry LE


Is your problem that the vehicle will not crank and has no power, or that the door lock remote is not working? Im not sure that I understand your question and dont want to give the wrong answer.
There are no "codes" persay for anything but radios as far as end user procedures go. Programming doors on a 2000 camry is...fun to say the least. the procedure is published all over the web and very weird, but thats what they designed..
Short version is, Doors all closed, Ebrake on, key in your hand you in the drivers seat. Insert key and do not turn, then remove again. Do this TWICE. Now key is out, within 45 seconds, pres the electric LOCK button on the door LOCK-RELEASE-UNLOCK-RELEASE and repeat 4 more times for a total of 5 cycles. After the 5th time is complete, open the door, then close the door. Then do the LOCK-RELEASE,UNLOCK-RELEASE thing another 5x. At the end of this the door locks SHOULD cycle by themselves twice, if they do not...cycle the ignition key on and off again. and see if they cycle. I=When they cycle trhat means its in learning mode! Press door both buttons on yor remote at the same time, then release. Then do the next remote the same way. That is how they designed field programming.

How do I turn off the car alarm? There's nothing in the manual. (2004 civic hybrid)


Unlock the drivers door twice. The other doors have to be closed and if their not electrically closed it'll still not reset. Double lock the drivers door with the key all the doors should lock.. The alarm should stop. Unlock the drivers door and then get inthe car and start it soon. the sysstem should go though a full reset and it should be normal again.

All 4 door lock will sometimes lock by themselves after you shut the door "unlocked"


Seems to be built into the Toyota security system. Occurs when you lock, then unlock the car and let it sit for 1-2 minutes.

Locks that unlock on their own


One of the lock actuators is bad. It's not locking or unlocking all the way. watch the locks while working the lock and unlock switches. If you see a lock with a sluggish response, thats the bad one. Note-- Over working the locks while testing will cause over heating and locks will stop.
