I was driving my 2017 Accord Touring the other day and all the warning lights came on the dash and were scrolling through. All the yellow symbols were on and the center message area just kept scrolling through, every warning was showing trouble. I looked through google and youtube, I found some others with the same issue and they said the battery was bad, my battery is two years old and it shows 12.55 VDC with the car off and 14.25 VDC with the car running. There are no codes. Other videos show people just hold down the power button on the radio for five seconded and a message will come up to reboot the system, I have tried this many times and I can't get any message to reboot to come up. I have disconnected the battery for a little while and when I connect it and start up the car all the warning lights are off. They will just come back on a little while later when driving. The car seems to run just fine, no misfires.

Has anyone seen this before? I have an appointment with Honda next week, I just didn't really want to spend all the $$ if there is something that I can do.

Thanks in advance.

 

ZERO Codes? If all the "lights" are on, is one the Check Engine Light?

On a guess and simple to do. Disconnect the battery - yes I know you said you did. Clean the terminals and while it is disconnected, connect the two cables together - this will drain/draw and stored voltage.

Is this a four cyl engine?

 

That's right there were no codes on my scan tool, it is the Touring model with V6, I did clean the battery terminals when I had them disconnected, I did not short them together.

 

So we had it at the dealer and they said that the rear ABS sensor was bad and that was causing all the alerts. I am still not sure, if the sensor was bad, wouldn't it just flag the ABS warning light on the dash? why would ALL the alerts come on, every alert was on the dash saying that every sensor and function was failing.

I brought the car home and put a new rear sensor in myself, When I started it up at the dealer to bring it home, none of the warning alerts were on the dash, I don't know if they cleared them or what. After I replaced the sensor I started the car up and some of the alerts were on, I thought maybe it was because I had unplugged the sensor and installed a new one. I went into the TPMS and recalibrated it because the speed sensor is also the TPMS, and all the warnings went off. I will see what happens tomorrow when I drive it farther.
