Just curious...

Can you pass your inspection with the ABS light lit up?

 

Not really related to the SAH thread, but it depends on your state and who does the inspection.

I live in CA and just got a smog inspection on a 1995 Honda Accord with the ABS lit up and they said it did not matter. It passed.


Good Luck

Sorry for not being more clear...

It's actually directly related because a few minutes after starting my car I get Service Active Handling, Traction Control and ABS all at one time causing my ABS light and traction control light to activate and I'm unable to to use my traction control button to go into any of the other modes.

I was assuming they were all linked to a similar problem. I had been reading the thread to see how to potentially resolve it.

I would find it quite odd if they were not related yet always "went off" together and never individually.

I need to have my inspection done this month and was wondering if I could get it done before resolving the issue that this thread is about

BTW, my car is an 07 and the problem started happening at about 60k miles. The only noticeable thing while driving is that SOMETIME the ABS will activate while doing any type of stop, but like I said, it only happens after I get the service handling, traction and abs all at the same time.

 

I filed the form today. Same problem on my 08. Thanks for the info. By the way my part has been on order for over 5 weeks and they say about 2-3 more if I am lucky. Not good for GM as far as I am concerned. Love my Corvette but very mad at Chev.

 

The only thing that is common is that they are all issues related to the electrical system. I own the GM service manuals (2006 Z06) and have an Autoenginutiy scan tool.

Since I am about to get on a soap box about this issue, a little background:
I used to be an advanced avionics technician in the Navy (before I became a pilot) and I KNOW micro miniature troubleshooting and component repair.

This todays cars, especially our vettes are like fly by wire jet aircraft. So many complex systems, but poor redundancy. There are no back up systems, so if something goes wrong your screwed.

All that being said, I think that (the complicated electrical system design, computerized driver assist so the average driver can handle a car with this much power) and cheap electrical components are the main culprits of all these electrical problems people are having.

Add in poor connectors (PROVEN susceptible to open circuits due to fretting and other types of corrosion), poor weather/climate depending where you live, and it all equals electrical problems that are described throughout this post.

I personally will NOT DRIVE MY CAR IN THE RAIN. I live in So CAL so I don't have issues with snow, or worse salt corrosion from the ice trucks.

I find that mechanics, including GM dealers usually don't know s**t about electronics. They know how to turn wrenches and fix MECHANICAL systems. They are good at what they know. These electrical systems are VERY complex. Great when they work, nightmare when they don't.

I am firmly convinced that if you want to fix it, do it yourself. Buy the manuals, buy a scan tool and read to codes, troubleshoot and follow the schematics. If you don't know about basic electronics (that is all I believe you need in this case), learn. Google it. The information is out there.

Follow the wires to the connectors, the GM service manual show you were most of them are located, once you find the connectors, open them up, spray them with contact cleaner, make sure the pins are not bent, broken, missing, loose, etc. If the connectors are in locations that get wet apply Dielectric grease after you clean them. Put them back together and I think you will solve the problem, or at least find the cause.

I know it seems like a lot of work, but you WILL know your car better than the GM mechanics do IRT the electrical system, and save a s**t ton of $$$$$.

Good luck. Hope this helps.

Well I filled out the ODI Contact form and referenced the open Investigation #.

So that's one more they can add.

I'm going to give my local dealer a call just to see if they've handled this situation in the past. They have very good corvette techs (so I hear...I've never had a dealer do any work on my car) so hopefully they know about the issue and know about the fix.

I don't have the time or patience to worry about messing with the electrical system in thsi car.

 

It has been posted here in this thread cars from 05-10 ( I think there is one ZR1 with the problem too ).

You can add me to this list. Mine is a 07 base model. My car is at the dealer ship now but I am not getting the braking problem most are getting. When the SAHS come on the brake light get stuck in the "ON POSITION". I have been almost rear ended twice because people can't tell if Im braking or not.
I have had the Brake switch replaced and recalibrated. The SWPS replaced. I have unpluged and repluged everything... I can't count how many times and it's still not fixed. It was at the dealer yesterday for the SAHS and It's back there again today... Now I'm waiting to here what next. BTW, I am not under warranty so all the fixes that haven't work I have had to pay for. I guess Im lucky so far that I have not had the car try to brake on it own. It even dose it even when I had TC off. I know of 3 other forum members who have the same problem with the brake lights staying on when they get the SAHS.

 

I have filled out the ODI contact form and have filled out the formal complaint form. Thanks for the info.

 

I have done this... Cleaned "ALL" the connectors. Made sure they were all good and not broken, bent, loose or dirty. I have the manuals.. It helped to find all the connectors. I have replace a few things ( see my posts ) and I still have the problem. Now, just short of replacing all the wiring harnesses I dont know what more to do. I guess I could follow each wire in the car but that would take for ever. I'm better off just putting new harnesses in it. The only things I have not replaced is the EBCM and the ECM. I have had them reflashed by the dealer just to cover that base. Anyway I have given up for now and I'm giving the dealership a shot at it. Also if somthing was to happen. I also wanted a record showing I gave GM a shot at fixing it.

 

What codes is the dealership finding? Have they been able to pull the codes when the error occurs?

 

At first they could only get the C0161 code ( Brake switch ). SO I took it in when the SAHS was on the DIC and the brake lights were stuck on.. I told them they needed to read the codes before they turn it off. Well I just talked to them this morning and someone turned the car off so they are going to take it for a drive to try and get it to come back on. SO no word yet on the codes. But as soon as I here from them I will post them. I did give them a copy of the PM you sent me and they are supose to be calling GM tech.

 

Your issue seems to be different than mine.
Mine was a buch of communication errors.

 

OK here is a up date. The car still only showed the C0161 ( brake switch ) code. Even after they had just replaced it AGAIN and only drove one mile down the road before SAHS came back on. They did all the testing of the wires and wire harneses and could find nothing... untill the tech was looking over the BCM. He accidently banged it when working down there and herd a "click". Then looked behind the car and found that the brake lights had cut off. So he drove it again the SAHS came back on ( Brake Lights stuck in the on position again ) and he tapped on the BCM again and once again the brake lights cut off. So they replace the BCM. Now I have about 300 miles on it on "NO SAHS". SO far so good. I hope this fixed it for good.

 

I have recently purchased a 2005 model with the telescoping steering column and after 3 weeks with the car, it gave the SAHS message. I read the info and was happy to bring the recall notice to the dealer.

But they said that recall does not apply to my car. I called GM directly as well and they said that recall campaign is not a valid recall.

I have not had the braking or swerving. I am in the hunt for a code reader now and will pull down the panels and take a look soon. Has anyone else run into this issue with the dealership not having that recall available. or was it just certain vin numbers?

 

I've put a new SWPS in my car I will try this Thanx, Stan

 

Where is it at in the picture Tom? Is it the orange connector??

 

The SWPS is the black plastic thing with the redish/orange electrical connetcor,

The red part of the connector is the TSB improvement comp they used to try to fix the problem...

 

Thats it Stan,You undo the steering shaft and slid it out. It is a white circle piece.About 50.00. It really didn't fix the car a 100%

 

For me the ZIP TIE worked for a while. When it failed, I removed the connector and slightly bent the pins in the SWPS. So far, no issues.

Thanks Bill. I deleted my post. Don't need the extra pics
