No problem, here to help. I thought I mentioned that it failed on me too almost threw me into a car. I thought I had put that in, but I guess I missed it in the hurry to post. The NHTSB wrote me today and I responded with a similar post. Looks like they are taking this VERY seriously. That is great news for Corvette owners!

 

Hello all,

I took the liberty of photo documenting the procedure on how to install the TSB 06-02-35-002B GM Service Bulletin Fix. I did it on my 2006 Z06 tonight.

Run the slide show on slow and it should tell you everything you need to know to install the part and or test your SWPS connector yourself. If there is a loose pin or bad connection to the pins, it should fail on you when the ignition is turned on (engine off). Turn the ignition off and it will reset. Turn ignition on again (engine off) and test again...if it fails, then the problem is beyond this service bulletin and the harness, and or SWPS. Without the Schematics, I cannot tell where the other connectors in the chain are. Maybe downstream the harness to the computer, there might be another connector for those who are still having issues or the pins are bent or broken in the SWPS connector itself.

NOTE: For those that are not comfortable with electronics, disconnect the battery first. I did not but had the ignition OFF. No ACC with the radio playing either.

If it fails again, I would not drive it until it is fixed by the dealer. Don't hold me liable if this fix does work for you, you still get the "SAH" message, and you drive it and crash. I'm only trying to help, but I can't help stupid.

Hope this helps a little and gives some piece of mind until they come up with a legitimate fix (like a totally new connector.)

Very Respectfully

 

You are the MAN! I just recently started to have the "Service Active Handling" come up on the DIC.

Over the past few months I've noticed that the seat and steering column haven't been going to the "exit" mode. The steering column does retract, but doesn't go back to extend, when I re-start the car.

This thread is exactly what I need!

Thanks again for posting your pix and procedure for the fix!

 

gr69ss,

Glad I can help. Don't know why the steering column is not acting normally, but it definitely sounds electrical. I believe the SWPS only tells the computer which direction the wheel is turned (thus which way you want to go). I do not believe the column movement (in, out, up, down) has anything to do with the "Service Active Handling" warning. However, if the harness is pulling on the SWPS and there is an open circuit, that will give you the warning.

I would check motor and connections underneath. The harness could be getting jammed against something or being pulled when the column is moving. I didn't really check to see how everything else was connected, but I did see the motor down there and you can watch it run. You have to lie on your back and reach up and move the column electrically and manually. Little uncomfortable but well worth the hassle. The harness is all electrical taped together. If it is too tight CAREFULLY cut or peel some of it away (do not cut any wires) to give more slack. All that is holding the wiring bundles together throughout the car (all cars are the same) is electrical tape...with maybe some wire loom on top.

Good luck and let us know how it goes!

 

Wow! That is one impressive writeup!

 

Excellent writeup. I think I will do this on my 08 if the handling message ever pops up again. I just got mine back from the dealer and they replaced the body control module as well as the skip shift solenoid. They said it was good to go but I know that the handling message will pop up again. I have worked in a car factory for 21 years so I have a little auto experience. I sure hope it works and that my brakes do not suddenly get a gremlin in them causing something bad to happen.

 

Got an email from the NHTSB a few days ago. Responded with my experience. They specifically asked if it was dangerous. I said YES, it is dangerous to have your car brake and turn itself without direction, but what the dealer did seems to have fixed mine.

 

I had the message come on Thursday morning, and the car wouldn't go in competitive driving mode all day. Read about it on here and decided to take it to the dealer that night (we have a dealer that has a service dept open till midnight on weekdays here). Told them what I'd read and said if that's the only problem they can find that I better not have to pay for it, they agreed and performed the tsb free of charge (clip over the connector in the steering column, thought they described it as more of a comb to hold multiple wires together in a bunch, so I'm not sure they did it right even).

The message went away, but it was on and off that day anyway, and I've noticed that once driving with TC and AH off for a while, it won't let me select Competitive Driving mode - it's either TC on or TC off, no AH options. Does that mean it's still screwed up? Or is that normal after driving with the TC and AH off for a while? (10 min or so?)

You can see pics of that "comb" TSB and procedure here:

Don't know why you cant use CDM. Hold down the button that activates the different driving modes for longer than 6 seconds (which turns it off) and turn it on again.

The SAH message (warning) is reset when the ignition is cycled on and off. If it doesn't work, take it back. Could be a computer issue or something else...sound like it should be working now though.

Good luck

 

Thank you! It looks like the way they described it is different from what's going on in that picture.. I'll have to pull it apart and check it out.

Holding in the button for a few seconds once I was locked out of CDM allowed me to go into CDM on the next cycle through the button.. thanks. Still worried why it won't just go in at any time.

 

I just read this post.
I'm getting in touch with my local dealer service manager today to talk to him about this.
Being a new member of CF...this is the first I've heard about these problems. I would like to thank everyone for being more concerned about my safety than GM is.

 

NVL_AV8R- I want to thank you again for posting the procedure and pix. Took ~20 minutes start to finish, could've done it faster, but I kept referring back to the pictures and notes just to make sure I was installing the comb correctly. No more codes and the seat and steering memory functions properly again

I can't believe that the dealer is charging big $$ for a 10-15 minute procedure installing a $10 part Thats why I love this forum so much

 

08 vet,

The dealers WILL NOT do this TSB UNLESS your car is deplaying "SERVICE ACTIVE HANDLING" and those codes show up in this computer.

You can do it yourself by following the photo instuctions at this link.

I did it myself because I have more faith in my own knowledge of electronics than I do in the dealer.

Good luck

 

No prob. Glad I could help. On another thread in this forum,

my top flew off my car as well last week and GM is pushing the fix. GM is getting there **** together finally, and they really care about getting peoples cars fixed properly. Maybe the Federal Tax dollars infused into the new Governement Motors finally trickled down to the customer service department.

Contact this guy below if you are having any issues (includeing the SAH) the dealer will not address. He is one of the official GM reps and he calls me EVERYDAY, to give me an update on what the dealer is doing on my vehicle. If he doesn't because he had the day off, someone else from GM calls me to give me an update!

People having ANY serious issues with dealer service departments not fixing TSB items, contact GM direct:

I spoke with Ernest (866) 790-5600 x 12969 who helped me out. He entered my VIN in the system and input my complaint.

 

[QUOTE=NVL_AV8R;1571446817]08 vet,

Thanks for the heads up. I will do it myself when he refuses to,
I still want my dealer to know that people are having this problem.

 

Message came up again this morning upon starting the car, hadn't even put it in gear yet. Going to look at it myself tonight... maybe they did the TSB wrong.

 

You harness may be too tight and it is still pulling on that connector, or the connector is worn out. Use this to check it yourself. Some Dielectric grease might help as well.

If this doesn't work, then it could be a problem somewhere else in the harness.

Good luck.

 

Sorry to hear that
Please let us know what you find.

 

If you guys don't get anywhwere with that fix, try this.

I had a bunch of issues with my top and GM jumped through hoops to help me. Called me EVERY DAY UNTIL IT WAS FIXED! Call Ernest (that is his direct line) and tell him the problems. GM gives a **** now...probably got the tax dollars to pay them.

 

Hi.

This is my first post. Having had the car for only about a month, my 06 Coupe has periodically shown the signs mentioned. It wasnt until last week that I got the "brake lockup". That was scary to say the least. I'm pushing the dealer to repair as much as I can since its still under the 5k/3mo warranty that they provide on purchases. Unfortunately I'm JUST off the GM warranty so thats no use.

I took the TSB for the clip along with this posting to the Tech who said that the majority of the codes that came back (The light came on JUST as I entered the dealer) were "steering wheel" related errors. He agreed that ordering the sensor along with the clip was a good place to start. He also said that he would do some digging with GM and see what else he could find out about this issue after he read the post.

I have to say that I LOVE my car. I drove an 04 Lambo just prior to buying my 06 Vette and was hugely disappointed by the ride (like a go cart), and the fact that the V10 sounded like an Indy car (ya...I know its a personal opinion thing) The exhaust, even factory, on my V8 sounded so much more aggressive....... BUT. I am upset by the fact that I had been under the impression that Vettes were better engineered and better quality than I am seeing presently. I would expect this type of thing from a Z24 (and have experienced it first hand) but would think that GM would do a little better QC on their flagship supercar. I also am somewhat put-out by the fact that GM doesnt offer a "perk" warranty on Vettes... It would certainly be nice to see some type of special coverage offered to cover issues like this "Service Active Handling" problem. These types of issues in my mind should be covered under a 10yr+ manufacturers defect warranty (faulty engineering?)

Well I've said enough. I'll reply on how goes the repairs/fix.
