2002 Hyundai Sonata Start/Alarm Shutdown.

Need help gang, 2002 Hyundai Sonata 4 cylinder, automatic. Battery drained down; then charged and tested battery. Battery held charge and load drain test on parts store machine. Installed battery, turn key and the alarm goes on and off continuously with flashers and dash board lights blinking on/off. No power to the starter or other car components (headlights, radio, etc.). Key alarm when pressed (this is not keyless entry system) only shows red light on hand pad (little mini pad with key). The door locks don't work remotely, manually ok. Will check all the fuses tomorrow. Could something somehow have drained the battery and shut down the alarm system? Does the alarm need to be reset to start the car? I've owned the car brand new. Before this the car always ran perfect. Waiting for your answers, Thanks.:wink:

Hey gang, fixed my own problem. I read the owners manual last nite at work. When the alarm disingages the car I assume it is doing its job (break in, etc.).
Locking the car down. To uningage the car you must leave the key in the "on" position for 30 seconds to reset the alarm to allow you to start the car. Other thing, I have to figure out why my battery drained down. I have 525 cold cracking amp battery in the vehicle. Manufacture calls for 700 CCA. I am going to put a new 700 cca battery in the vehicle. The alternator belt is tight and good. Any ideas about this? Looking for answers.

Thanks for the info on how to reset it .. I have a 2005 but its probably the same reset proceedure ...........

As far as the battery , yes , you want to keep a 700 amp in it . the difference between 525 and the 700 is that the 700 amp gives you alot more " zap " ( muscle ) to turn the engine over and not put a drain on the battery to do so . As far as it just drainning sitting you might check your battery cables and make sure thy aren't corroded and are securely attached to the battery posts , plus of course make sure nothing else is running ( like maybe something plugged into a cigarette lighter outlet like a cell phone or radar detector ) ..... I would be courious to know the cause when you do find out .

Me again, bleomoran... Driving the car last nite around the neigborhood the headlights and radio dimed down. Tried to drive the car back home. Car shut down in the street. It would not take a jump start. Ran home and put a fully charged battery in place of the old one to start the car. When the battery dies the car locks down. I made the mistake of putting the car in park with the dead battery and then I couldn't get it out of park unless I had a fresh battery. Please make note. With the new battery I drove it home a 1/2 mile. I then pulled off the negative terminal and the engine shut off. Did it again with the same results. My Conclusion: The alternator is bad. It doesn't recharge the battery. 2002 Hyundai Sonata 5 yr./ 60,000 mile bumper to bumper warranty. I got 61,000 miles. 3.5 yrs. I've owned new. The dealer says I am out of luck for them to replace it free. Alternator part Pepboys, $214.00/core 80.00/lifetime warranty. Chilton labor, 1.6 hrs. $105.00. total $337.00. Also when I brought the car new they mistated the horsepower. Class suit they allowed us a work gift cert. or 2 more years on warranty. I choose 2 more years. Dealer knows nothing but admits to suit. Hyundai Corporate knows of class suit but can't explain it. They stated we will probably get back to you in a month. I would like to know if they added on more miles for the warranty with the extra 2 years. I have to find my paperwork. Alot of stone walling with Hyundai. Dealer and Corporate. I now must see how difficult it is to replace the alternator myself. Timing Belt should be changed at 60,000 miles. Timing belt goes around the water pump. Just letting you know. Any ideas gang?

In general, I know that changing an alternator usually isn't too bad, just a matter of loosening the belts.. But I've never tried it or even had a reason to look at the alternator setup on my Sonata. As for the timing belt, yes, the timing and balance belts both need to be changed at or near 60k miles. I had this done at a local shop and the entire 60k mile service w/ both belts ran me a little under $800 and 2 days without my car.

MXlonerider, I will let you know how this works out, changing alternator. Thanks, Brian...

bleomoran, alright gang. I got the alternator out. 2 bolts. 1 nut and the wiring harness. It was alittle tough trying to get the alternator out. I had to loosen two wire brackets on the intake manifold and really wedge this baby up and out. No room to goe out the bottom. Took me about one hour. Now on to the parts store to test the alternator (out of the car) under load on their machine. I looked around for a rebuild kit but the parts stores don't carry them anymore. One does but my alternator is to new. This story will continue. I promise.
