2002 Hyundai Elantra Q&A
2002 Hyundai Elantra Question: What's could cause this?
I currently have no interior lights or radio, scanners are unable to pick up codes, and check engine light is on. Recently replaced alternator and battery. Battery was drained after 2 days of use. Checked all fuses and all are good. Car is a 2002 Hyundai Elantra. - jeff072581
if the battery went dead after two days then you should check your charging system and I would scan test for codes. check for power going to the alternator you could have a defective alternator or battery I would also recheck your fuses using a test light - goodguy
AGREE WITH GOODGUY BUT TRY A BETTER SCANNER FOR CODES - globalhelper
If the scan tools aren't communicating with the car, and the battery is going dead the next move is to charge the battery again with the cables disconnected, then when you connect them start measuring the parasitic drain that is killing the battery. Once you have that measurement, you can go to each fuse in the fuse block and measure the voltage across the fuses. Any fuse that has current flowing through it will have a voltage drop across it. (Old way to do this is to simply pull fuses and watch for the drain to be eliminated) Once you solve the drain, if necessary then we can talk about communication network diagnostics. I suspect you have a module that is failing and disrupting communication. - cardocIII
