Hi everybody, so the other day while I was driving then all of my warning lights came on, the tpms, the shawd, the emissons sometimes, the trailer stability assist, the abs, the brake system, the airbags, the vsa the tire pressure systems read system function error.The cluster does read the rpms or the mph. This is very concerning. Does anybody know what could be going on?

I would double-check the battery charge and alternator. I had a bad alternator on my RDX and it was stealing power from my battery until the volts got too low. Ended up getting all the same X-mas lights on my dash also. Once I charged my battery, the light went away and I was able to drive to the shop for more troubleshooting. Same issue with my TSX a few months ago when the alternator died and ran the battery down.

There is a possibility a weak battery or alternator might be (part of) the problem. It would be the easiest thing to do is check with a battery charger/maintainer with a battery % reading.

The battery and altinator are linked, so a malfunction may be difficult to find without troubleshooting, like MrGold35 said....

I'd bring that in to service for a good look over...

Simple way you initially check your alternator, is to check for sparking.

While it is daylight outside...locate the alternator.

At night, very dark out, do not use any light...open the hood and look in the general area, where the alternator is located.
Have someone start the car.
Did you see any sparks?
If yes...change the alternator.
