Service active handling message
While out driving today I got a service active handling soon message on the DIC and the light came on the dash. I hit the reset button which cleared the DIC message and the dash light remained on. I assume this is what is supposed to happen until it is fixed. I then pulled over and turned the engine off and let it sit for a minute and started back up. The light stayed off and I had no service message. I pushed the active handling button to turn it off and the light went on indicating it was turned off, then pushed the button again and it went back to on and the light went out and the DIC said active handling on. Everything seems to be normal now, but having had the initial error message worries me. Has this happened to anyone else and cleared up? Will this probably strike again later or is it just a wait and see type of thing? What is usually the problem with this type of error?
I appreciate your feedback and expertise.
Thanks,
Mark

I suggest that you pull and post the codes:
http://www.c5forum.com/ayc/dtcdic.php
OR
Include the H or C or HC that follow each 5 character code.
Next time it happens (it likely will) pull over and pull the codes BEFORE you shut off the ignition. Some codes disappear once you shut off the ignition without setting a History code.

Steering Wheel Position Sensor (SWPS) failure. Most likely the sensor is bad or going bad. You can check to see that the steering wheel is completely centered while driving straight on a flat road. If the wheel is not centered and/or the cars alignment is off, you could get a similar error.
Clear the codes and take the car for a drive. How to clear the codes is covered in the link and/or video in the previous post. If the messages come back, pull over and pull the codes again BEFORE you shut off the ignition.
Those codes that return are the ones you need to be concerned with. Most of your above codes are related to a battery issue that may have already been corrected. Did the battery get disconnected or go low recently?

Thanks for the info, I will clear them and see what happens. If it happens again I will pull the codes before shutting down and post them again. Great info, thanks again.

I also have been struggling with the dreaded "Service Active Handling" message for quite a while. I have a 2001 vert. I've done all the suggested fixes listed in other posts, fix grounds, check wiring, measure the SWPS voltages, alignment, etc. without success.
The only TCS DTC I get is C1287 H. I've taken it to the dealer and they say since it's not a current code there's nothing they can do. What I did discover is a GM service bulletin that applies to 2001 - 2002's that have this condition related to DTC C1288 at http://www.corvetteactioncenter.com/kb/search/c1288. It is a software update to the "ABS" module. I plan to have the dealer check and update on my vehicle next week. It's the last step before replacing the SWPS. Hope that helps.

The Service Active Handling code does occur when the communications have been disrupted or when the steering rack has been disconnected and connected 360 deg out. On a rare occasion it can happen if you hit a bump at speed and the abs sensor gets jarred. This is more than likely what happened to you and the sensor lost communication. Restart the engine and no code. If the steering wheel was changed then the SWP sensor can get messed up. This usually occurs when someone puts an aggressive alignment--happened to me or they unhooked the steering shaft to have the harmonic balancer replaced, etc. and the steering shaft was moved 360 degrees. If that happened the code will not go away and the light would stay on. A Tech2 can be used to reposition the shaft or the SWP sensor can also be used to place the shaft-in correctly by measuring voltage.

I had this problem as well. First the service active handling and ABS lights came on, then later my HVAC starting shutting off. After hours of searching and trying to find help, I finally found the solution to MY issue. This very well could be your problem too so it is worth a look. I serviced my ignition and have not any issues since. Here is how to do it.

I took 8vette7 advice (thanks) and went to a different dealer. My Service Active Handling message on my '01 seems to have been fixed. Here's what was done;
1) Reseated laterial G sensor connector - sensor under pass seat
2) 4 wheel alignment - steering wheel is now cenetered. This is the second alignment - only a differnt dealer.
3) Updated software on EBCM according to GM service bulletin for 01 - 02 model years.
Don't know if this is related, but I also had a power steering high pressure line leak whicih I had the dealer replace. So far so good.

Got another TCS message again
It's taken a month or so after clearing the last message but today I got another TCS message on the DIC and Active Handling Light came on. Pulled codes BEFORE I shut down this time and they are as follows.
TCS C1287 HC
BCM B0502 H
BCM B0507 H
BCM B2482 H
After pulling the codes I cleared the messages and the Active Handling light went out and all is well again. Not sure why the DRL and Backup Relay errors came up. I don't seem to have a problem that I know of there. I did change the backup lights to leds a few weeks ago but they work fine. Any help on what to look for. Since the errors only come up very occasionally and everything works after a reset is this anything to worry about that it needs immediate attention or can I take a wait and see type approach?
Thanks

Error codes
I knew reseting did not fix the error but was thinking that the TCS error was not the type of error that would disable the vehicle and at least I had some time to work on it. The steering wheel is positioned correctly. I think the grounding points are a great place for me to start. Thanks for the info on finding them and how to clean them up.

Mine has been doing this same problem since 2001. Everything done that was mentioned above so i just deal with it. Sometimes 8months to yr between warning and sometimes three times a day. But for the most part it's mouths between warning and i drive my car 365 days a year. Rain,snow, sleet whatever the weather is. I just except it's part of the car and don't worry about it. Cause i know it's not going anywhere.
P.S Wasted enough time and money chasing my tail.

Ran across this on YouTube? What are your thoughts for those who wish not want to pay the $400+ per rear shocks and go with the c6 zo6 shocks. (Basically removing the shock sensor from the old shock and tie it off leaving it plugged in and replacing with conventional appropriate regular shocks). Just curious if anyone has tried this and what’s their outcome? Understanding one would lose the ride control selection shock feature and still not have 80 mile an hour limit. Also note in the comments on this video that this particular person has done this successfully without any error messages or 80 mile an hour limit.

Hello Red,
I got Bilstein shock absorbers on my 04.
To use these instead of the stock ones I use simulators on the connectors.

Hope this helps.
