Got in the car after class and got showered with lights on the cluster. Knew right away it was the battery from what I've read on here.

Drive straight to the parts store to grab a new one. Buddy tested the battery and it ended up being stronger than the one I was buying.

Anything else cause this or should I just take this battery as a loss?

Changed the battery and lights are still on ..

SH-AWD
ABS
AFS
VSA

That's your alternator going out. Mine literally just did the same thing couple nights ago. Alternator was toast, had all the same lights on.

^It's the next logical step...

I was going to suggest the same its usually one of those 2 at least in Euro models.

alternator.

Alternator replaced not even a year ago & check out good.

Disconnected the battery again for amount 30 min & held the terminals together for about a minute.

ABS and VSA still on. Went for a cruise and they finally disappeared.

Would have helped if you told us that in the OP too

Came home from work last night, stopped at a light & the AWD display was showing 2 bars on each wheel then she lit up again..

Also developing a high idle, anywhere between 1100-1500. Great times

thoiboi

both batteries and alternator could test good but still be bad.. check all your connections, cables, grounds, and I'd look into another alternator/battery.


Electrical problems are unfortunately TOUGH to troubleshoot on your own.

Tell me about it..

Just dealing with it day to day, don't have much downtime between school/work.


Tempted to drop it at Acura but $125/hr diagnostic fee isn't very enticing

New alternators go bad all the time. I've had 2 go bad on me within a 3mo span, my money is still on the alternator. You have all the symptoms of a failing alternator.

The errors seem pretty random. Can you pull the codes from the nav messages?

Never tried that before, I'll look into it..

I can grab another alternator. Tested the current one yesterday and even under load it didn't flinch under 14V. Trial and error for days..

The tensioner could be going as well. It was replaced last year with the alternator

New battery - Check
New Alternator - Check
Grounds - Check
Cluster full of lights - Still going strong




Best part about this whole fiasco is that it started right when we finally started getting snow. Been an interesting week or so of snowy commutes driving FWD with no traction control.

Out of ideas.

Have you held the battery cables together?

Spoke to a buddy who use to be a Tech at Acura and he says it's most likely a wheel speed sensor. Have to get the car scanned & go from there.

Right rear speed sensor, $200 later & all is well..

Except the VSA light is still on…

oo7spy

Another battery cable reset?

Wish it was that easy.

Have a code "Sensor logic failure". Found a procedure to reset the light just haven't spent the time yet.

I am not sure which car you own, my 2011 RL came up with scrolling check SHAWD, ABS, AFS, VSA etc etc.
Replaced the battery and went away for a few days and the errors returned.
Dealer replaced SAS and AFS sensors which correct the problem.

Hey J,

What ended up happening with this did you figure it out?

teh CL

iTrader: (1)

No J here..

Solved it with this thread..

84-1 Sensor logic failure

RL09

Could've sworn. Memory failing me.

it seems to have been a steering wheel angle sensor that needed reprogramming. And it was peculiar.
