avid, i have a c5 vette, if you have a c6 look at the forum for dic codes for the c6. I dont know if you get the codes the same way i do, but the way i get them is turn the key to on and reset all msg's. Then hold the options button and press the fuel button 4 times and it will go through the computer and give you all the codes that are present and history. Write down your codes and look at the dic code list and that should help you. I am in east tx,close to tyler moved here 5 years ago from dallas. If you want call me and i will guide you through it. 903-746-9360. I will go and look at the c6 forum and see if i can find it for you.

 

I finely found that if i put my car on a small battery charger it quit getting service active handling messages. I believe this is all related to battery voltage. Most sensors us low voltage. I don't drive the car more than once or twice ever week or two. I also installed a new battery but this only helped for a day or two old battery tested ok but was 6 plus years old. I did a lot of reserch before i came up with this. I dont think this is a fix just a band aid that works for me. This could be related to starter draw or charging system hope this helps.

 

Thanks for the info. Apparently this won't work on the C6, but we also have a C5 that we just got the shop manuals for, so this info will be a big help. Also if all goes to plan, Tyler will be home for us in about 24 months. Hope they have a Corvette Club there.

 

Not sure why you think the brake lights staying on have anything to do with the SAH message.

What does the BCM have to do with AH besides providing the signal path from the console switch to the EBCM? It won't initiate a SAH message.

Just because you get a SAH message that doesn't mean anything dangerous is occurring. The dangerous incidents are all sudden activations of AH (maybe) followed by the SAH message. The key operative word here is FOLLOWED. The sequence of events is important. Once that message is displayed Active Handling is SHUT OFF by the system and will not turn on again until the next ignition cycle. As reported above one person had to have their EBCM replaced and nothing was done to the steering sensor. It sounds like yours is EBCM related and has nothing to do with the recall or the steering sensor. Terminology is important as well since there is a big difference between the EBCM and the BCM.

I actually have inside car videos of the steering wheel being pulled out of the hands and whipping back and forth while an outside video shows what the car was doing. No Active Handling messages ever appeared on the DIC. None that said AH was active and none that said SAH. When the incident happened AH and TC were both turned off and did not turn themselves back on again. I would post them for viewing but the people who over react would take them the wrong way and get the wrong message from them.

We aren't sure what's happening with our car. We have been dealing with the SAH message suddenly appearing off and on, always after applying the brakes under certain conditions for nearly 18 months but it has never involved a condition that would result in a loss of control. We don't think our problem is related to the positioning sensor anymore. At first we did because it always seemed to happen after we switched drivers and changed wheel position. Recently, on several trips we've taken with other Corvette owners, we've experienced the problem and received a radio call that our brake lights are on. That can create a dangerous situation because people can't tell when you are actually applying the brakes.

Replacing the brake switch didn't fix the problem. They are replacing the BCM based on codes they got off the car the last time. I don't have a clue what talks to what in this car. All I know is I left the service dept, drove 1 block, hit the brakes, the SAH warning sounded and illuminated, and the brake lights remained lit all the way back to the dealer and were still lit as they pulled it back into the shop to plug it in to see what codes they could get off the car.

They can replace anything they want to try and fix the problem since all it's going to cost me with GMPP is $100 as long as it's the same problem every time I pull it in.

 

I've had my car do that time and time again.I thought I had it fixed but it is back again.This has been going on for three yrs.I had a 09Z that was doing the same thing,come to find out the SWPS and bearing fell out of the steering colume with 4500 miles on the car. Put it back in and reset the SWPS with a Snap-on Modis and it is fine.My 06 doesn't have the recalibration option in the Modis menu. Does anybody have a real answer to this problem? I'm tired of buying parts for my car.It was under warrenty when the problem started.

 

Just a update : 1000s of miles later and many track and autocross days I still have NO more SAHS problems. So if you have the same problem with the brake lights staying on when you get the SAHS. Have a look at the BCM.
BTW... the BCM never through a code. It was by luck that we found that to be the problem.

 

Just a quick question was this problem solved in the 09 model year?

 

No I've read posts about 09's too. There is a interesting read in the CTSV forum,same problems over there too. GM needs to step up here.

 

ode-z, i dont know you could talk with some of the senior members on here or go to the c6 section. I think GM knows, i think it's has to do with service. T hats how they make there money, but that's me talking. They know year in and year out the problems they have , but do notthing to correct it.

 

Thats really ****** guys!! I feel your pain and truly hope u all get the problem solved cheaply!! I just got my car. She has 4k on her so only time will tell if I get this problem or not. I haven't had it in the 700miles of pretty hard driving so far so fingers crossed! Problem is that she is currently getting a cam so after that GM will tell me to pound sand. If it does happen I'm relying on your guys hard earned footwork to help me with a solution!

 

I've got a 2008 Z51 and it just happened to me. At about 50mph it reduced power and started activating the front right side brake. Then it stopped, then did it again 3 minutes later. I was able to correct my trajectory but not a pleasant feeling having your car decide to drive itself off the freakin road.

 

Took "new-to-me" '08 to back to the dealer cos of brake lights being on and Service Active Handling message. 2 days later the same problem.. took it back and they now replaced bcm. So far so good, hoping this will fix it!!!

I have a 2011 GS, mn6, f55 with about 6k miles, purchased new. Last night i ran over a jaring bump/depression in the road, and it seemed as if I felt the ABS engage (idon't remember braking). After the bump in the road, both the ABS and Traction Control light came on, and the DIC flashes "Service your Traction Control". Also, the traction control button on the console stopped working when the warning lights came on.

After shutting down the motor and restarting (several times) the ABS and Traction Control lights and the DIC "Service your Traction Control" warnings returned. The car seemes to perform as usual, but I have not tried to push the car to the limit to see if the ABS or traction control will still engage.

Is this a common problem with the C6? What causes the problem and what is the fix? I know this may require a trip to the dealer to fully resolve the prooblem.

 

It's been a year since my last visit to the dealer for the re-occurring SAH, STC issues with my 06.

Several thousand miles, no DIC warnings.

I think they finally got it fixed.

 

Just had this happen to me for the first time last night on my '07 with 63K miles and telescoping steering column.

Was turning right into a parking lot, front brakes started to lock (could feel pulsing in the brake pedal) and DIC showed "Active Handling" - not "Service Active Handling". It was ok until I turned again (right turn) into a parking space. Since we were where we were going (club board meeting), we left it for a few hours. Had zero issues on the way home.

So what's the consensus here? Would there be codes to pull or just assume its the SWPS?

(I do have GMPP coverage at least!)

 

I cannot believe this is still going on. I had an 07 MN6 Coupe that I almost got killed in 2 years ago last month. The breaking applied to one side and the steering issue mentioned above presented. I unfortunatly could not correct the problem and ending up hitting a pole and being ejected from the car. Remarkably I wasn't injured, but I also though there was more to my incident than operator error.

I have been considering a newer Z06, but this makes me nervous...

 

Wow, i'm pretty scared to drive my car after reading this.... GM NEEDS TO FIX IT!!!

 

Had the clip done back in the beginning of November and no further incidents..(500 miles since)

 

Wife has a 2007, is it specifically a problem as well for this model year (2007)?
