Do you have any mods to the car? Aftermarket lighting, intake...

can you go to a store like autozone to have the battery tested for free?

abs sensors, yaw sensors, bad batteries/alternator have been known to cause the error lights. A lot of threads on this.

Hello, Yesterday i check again the battery. Is in 12.6v - 12.9v, But when i started the engine it keeps in 12 v......after 30 seconds up to 14.1v - 14.5v ....i repeated the process a few times, sometimes it goes up to 14v in 2 seconds but sometimes in about 20 seconds.

i realized that when up the voltage at 14v i can hear a rare sound. i think its heard in the alternator or very close. the sound is like a clicks or ball of bearing broken... i don't know how to describe the exactly sound..

i know that you say me that i need go to dealer or electric. The problem is that i'm from mexico and is too hard found a good electric here, all are thief jajaja

Thanks!!! :)

Howdy!

The Voltages you're seeing are within range of Honda's Dual-Mode Charging system. :)

In short, your battery voltage will fluctuate between 12.6v ~ 14.9v. The 14~14.9v is the 'High Output' (Charging) mode for when your Civic starts up, and then the 12.7v is the regular draw mode. ECMs/ECUs in general are sensitive to voltage 'cleanliness'; When they sense little hiccups here and there, stuff like this can happen. A worn alternator can make clicking noises--How does the car drive? Is it tough to start at all?
