Yes, but how is the battery?

NAPA load tested and it tested great. Right at 500CCA. My tester showed the same. Charging system good...

But...keep getting LKAS, ACC, Lane Mitigation and Brake System fault in dash.
How can I get these faults but computer shows no codes? NAPA had good computer tester and one I have both showed all good. Do some testers that only dealer has show these types of faults?

 

Can you test it out of vehicle?

Have you driven the vehicle since? Have a picture of your battery installed?

It is possible the Honda scanner will show better codes, but you should be able to clear.

 

If I remember, I tested it when disconnected but I will do it again.
Yes...we drive vehicle everyday. Codes show up as soon as it starts but again...using three different scanners, no codes are logged. Weird.

Does the green cruise light go on and off when you press main button on/off? (it is on the right side of the steering wheel)

If not - the clockspring in the steering wheel might have a broken wire.

I'll check but I don't believe so. It won't turn on because of faults.

Anyone ever hear of brake switch causing this issue? I was reading online and someone said the brake switch was causing one of these errors.
Hmmmmm....

Would not worry about the cruise button so much, not much brake switch errors here, mostly dead battery problems.

Make sure all your fuses are good.

2:30-4:00 mark here...

Picture if you can. thx

 

 

Thanks, was this battery a replacement for the original one under warranty?

 

Under warranty. Dealer replaced it about year ago.

 

 

Just an example showing 505CCA.

 

Sorry, so this is the 2nd battery?

 

I think 3rd. Dealer has replaced two under warranty because they don't last long in this South Florida heat.

 

Gotcha, I don't really trust those Honda batteries, Wal-Mart or warehouse stores are good.

You can try post # 7, but it may just need another battery.

 

Not arguing...just trying to wonder why you are focused on changing a battery that test good? Even when my battery was bad the last couple times, I never got these errors. I would think the errors would log some sort of code...especially since my functions are disabled.

 

No worries, it may just need a better scanner.

I could be wrong, but these lead acid batteries do not like to discharge a lot, that is what worries me.

I would crank the engine without starting it for 5 seconds, and test battery again. You would have to pull fuel fuse. Those testers can be wrong.

 

The issues you describe are indicative of a weak battery.

If your battery is sulfated, you can charge it and get good readings for CCA and still have a bad battery.

So if the battery was tested, what is the SOH (state of health), SOC (state of charge) and DOC or DOD (depth of charge or discharge)?

All that together will paint the picture of your battery (or boat anchor).

When experiencing issues it is a good idea to eliminate items that are known to cause the issues so you can get at the root cause.

Two other puzzlements.
“Codes show up as soon as it starts but again...using three different scanners, no codes are logged. Weird.”
Yup, weird bug if codes show up, what are they?

and, you live in South Florida (hope Milton missed you) so CCA is not important. CA and reserve capacity are.

YMMV

 

Thanks guys.
I have batteries galore. I have a several vehicles I can swap a battery with that have good batteries. They are bigger but at least can see...right? I assume the faults will go away immediately with a known good battery?

As far as no codes...can you guys think of any reason why I would get these faults constantly without throwing a code? It's not like this is a come an go problem. Any ideas on that?

 

2017. Having issues with cruise and LKS faults on dash screen and cruise doesn't work.
My code reader shows no faults? Are there different code readers that show more errors? Any recommends on what to buy?
Thanks

Your battery is just fine. Typical obd2 scanners only read engine/emission codes. They can't read all the different systems in your vehicle like the ABS, AWD, SRS, transmission, radar and camera.
A low cost scanner like the Bluedriver can read these systems. But know this, many faults with the radar and camera modules are not stored so you have to read them while the error is occuring. This is a headache for both DIYers and dealers.

 

I just spoke to Bluedriver and while it reads a lot of codes...theybsaid it doesn't read radar and camera codes. Is there any scanner for these errors at all?
Thanks

 

Well...that makes sense to me as I can't imagine no faults with my issue. And it is happening all the time...not intermittent.
Thanks. I'll check out the scanner you mentioned.

 

UPDATE:
I swapped battery with a 5 month old group 24 series. I know that battery is good and stronger than the Honda one.
Anyway...still showing same radar/camera faults so it's probably not a battery issue.

It's hard to believe my camera or radar went bad at the same time my car was sitting in the shade, under my house for four months.
Oh well...does anyone have a way to test input voltage to camera and/or radar?
Thanks

 

All the fuses test good?

 

I can't find any fuse for my radar or camera? Not sure which one to check...

 

Update: Bluedriver scanner found following codes. Attached screenshots.
1st screenshots was from partial system scan. I cleared the codes but dash errors remain but my scanner now doesn't read the same codes. Not sure if I should have cleared?
Following post are three screenshots and are from a complete scan AFTER I cleared above mentioned faults.
Remember, the dash is only showing ACC, LKAS, Collision mitigation, Road departure mitigation, Brake system error.
I also changed battery.
Anyone can make heads or tails out of this?
Thanks

 

 

I would check all your fuses.

 

First clear all codes, some of these can be years old and meaningless now. Then take the vehicle out for a little drive and check for error codes that are fresh.

Note that the warning on your dash (ACC, LKAS, Collision mitigation, Road departure mitigation, Brake system error) will occur anytime a problem is detected with the engine, transmission, VSA module, steering module, radar unit or camera occur. The PMC is programmed to disable most of these driver assist functions and turn on the warning lights.

 

Will do.
