Customer Question

My check engine light came on for no apparent reason, and I was looking for the ECU reset procedure. I have a 2011 Accent.
JA: Does the light stay on, or does it blink?
Customer: On steady
JA: Are you fixing your Accent yourself? What have you tried so far?
Customer: just checked fluids. I hadn't filled gas nor done any repair
JA: Anything else you want the mechanic to know before I connect you?
Customer: It's low mileage, only drive 25-30Km per week

Hi there. There isn't an ECU reset procedure per se. So the engine computer has determined there is a fault. The best strategy is to have the ecu scanned, and take note of the trouble code stored, so that we can go further with the diagnostics. Some automotive part stores will scan the engine computer for free, in the hope that you will buy some parts to fix the problem. The engine light doesn't come on randomly, so there is a problem. Impossible to say what that problem is without a trouble code. Hope that helps.Customer/p>

Thanks. That was so worth the 5 bucks!
I should have just waited until its oil change next week.
