Parking break and battery light always on.

[Ryan Heo]

Hi.My 96' I30 was replaced spark plugs on today morning. After that, I drove to go to a bank. Everything was normal before I started again to come back to home. The parking break and low battery light doesn't disappear on. So I turned the engine off and again it still there. I'm sure the battery is good because it was checked on the last saturday. What' wrong?I reset ECU but it doesn't work at all.

the brake light on usually indicates low brake fluid. the battery light does not mean your battery is bad or going bad. it more than likely means you're alternator is not function properly and you're running off of battery power. check those and let us know what you come up with.

The engine was gone 10 minute ago. I don't why.My I30 was towed in traffic while the was driving to go to market.I think the alternator was bad.
