Corvette505

When i started my car this morning three messages popped-up in the DIC:
Service Anti-Lock Brakes
Service Active Handling
Service Traction Control

Any idea what's going on? I did my brakes about a year ago, so they are good. My traction control button doesn't work now, so not sure whats up there. Kinda wierd all 3 would pop up at the same time. It feels like it driving normally, but I'm weirded out by the messages. Please help!

First thing is to check for is a loose plug wire.

Gearhead Jim

Our 2009 Z51 coupe has done that three times in 90k miles. Each time was at very low speed, like in a parking lot, and just coming to a stop. The warnings came on but nothing goofy happened with the ABS/TC/AH. Each time, I continued driving, shut the car down later, and it was back to normal after that.

Last time, I left it running and drove to the dealer; they read the code but it didn't really help them understand the issue.

Oddly enough, this is the first thing to check.

Then check the big blue connectors under the cover in the passenger footwell.

You can take the car to Autozone/etc and have them check to see if there are any codes to be read.

If it's serious, you may have to take it to a shop for repair. Dealer if it's still under warranty, otherwise get a recommendation from the locals for a shop you can trust.

Age of battery?

Battery is only 18months...

I will check the loose plugs, that makes sense, thanks a ton

I brought it to two places and no codes pop up n their scanners, they both said since it's not engine related it won't show. But they also both said that pulling spark plug wires would have nothing to do with Anti-lock Brakes, Traction Control or Active Handling. Any other ideas?

You need a code reader that is capable of reading ABS codes. I chose an Autel AL619 http://www.newegg.com/Product/Produc...9SIA2VF1HB6659 but I'm sure there are plenty of others. There is an excellent thread here: https://www.corvetteforum.com/forums...need-help.html Between the two, I was able to solve and repair this intermittent, highly annoying problem on my own.

They don't know this particular car. I'm not saying that the loose plug wire is your problem, but it is absolutely a known cause of those warnings here on the forum. This forum has more collective experience with the C6 than most shops and frequently more than a Chevrolet dealer.

I will grant you that a loose plug wire should have nothing to do with those warnings, but it's just not the case with a C6.

Is your car absolutely stock? Or have any electronic devices been added to it?

This is absolutely true - a loose or plug wire that is off the plug or coil pack is or "WILL" throw that code - no rhyme or reason why but it does - (Happened on my 2009)

Whomever told you that it does not is sorely mistaken - it is a known

If you have not checked all your plug wires for any loose connections at the coils or plugs then you need to do so -

If someone has HP Tuners or another scanner capable of scanning for ABS or wheel sensor codes or ABS sensor codes, you need to have them help you out -

It will be sorted out, it happens and there are multiple reasons why this certain message shows up

Thanks,Matt

I had 1 bad spark plug that through those same codes, a few months ago on my 2010. It was still under warranty, so I had the local dealer fix it.

Knob Jockey

Again..................it makes little sense, bud a bad/loose spark plug wire will throw those codes.

Typical (non-Corvette experts) shops will not be aware of this C6 'quirk'.

here are all the quirks I've learned here, battery, loose plug wire, connectors under passenger side floor as mentioned above, wheel sensor, EBCM, ECM. Mine was the EBCM... Let us know...

Had the same issue yesterday on my 2012. Turned out to be my 5 year old battery! New battery and all is well!

Got uid0

same issue here with a new yellow top.

Going in for scanning this week

I've read a lot that a battery could throw this code, but mine is about a year and half old and everything else runs fine and it shows plenty of juice. Don't wanna spend $120 on a new battery if it's not whats needed.

You all have convinced me to check the spark plug wire, i'm going to check them all right now......

Corvette505

Finally brought it into the dealer. Seems the codes coming back are about 7 of them, most of them dealing with LOSS OF COMMUNICATION with such and such . He did say they could spend 2.5to 4.5 hrs diving deeper into it,or he said it could be a battery. My battery is fully charged and is only 18months old Bosch Premium, that has a 36 month warranty. Not sure they'll honor changing the battery out if it appears to have a full charge. Undecided on what to do next?!

I got this message today and my rear passenger brake locked up on me, luckily I was in a parking lot going about 3mph. Hope that doesn't happen to you before you get it figured out.

Corvette505

Fuses and wires are all fine, pulled and replugged all of them. Bought and tried a scanner to clear them, but nothing popped up. Brought it to the dealer who cleared the codes only for them to pop up again, said it'd take 6 hrs of shop time to clarify what the issue is or if it's just a bad code, suggested i try a new battery first. Got new battery. All of this and I still have the issue........UGH!
