service active handling message on DIC as i was driving
the message randomly came on my drive this morning to go home. iv noticed a slight vibration in the brake pedal, but after i got home. turned the car off for 1 min, the started it again the message went away. anyone know why this happend? its scaring me as more problems might happen soon. and my brakes are good its not that. hopefully the service active handling doesnt come back. it is a chilly day today idk if that makes an impact

There are a crazy amount of things that can cause that. I disabled my AHS by disconnecting the steering position sensor. There doesn't seem to be a real fix for this issue, other than disabling the system. If the brakes lock up at speed it can be pretty dangerous

i doubt its brakes, i went up to even 140km/hr and braked fine. i was played a little bit with the tilt wheel by the steering wheel when i was warming up the car which maybe caused that message to show up later, not sure

Location would help, since if you are into the colder weather, or the tires where not warmed up yet, it's really easy to get into the ABS system (pedal will vibrate when the abs system kicks in as the tires [or only a single tire] start to loose grip during braking), until the tires do get up to temps/start to get performance grip again.
If it was not a tire cold or tire grip problem and you are sure that you where not getting deep into the brakes to cause the tires to lose grip, then suspect that one of the wheel hub sensor connectors is either loose, or the wheel hub sensor is getting ready to give up the ghost.
The way that the ABS system works, is it measures the tire speed of all four tires via the hub wheel speed sensors, and when one of the tires speeds drops way before the others, the ABS/AH will kick into keep the car straight during braking.
So on that note, pull the connectors off the wheel Hub sensors, clean the connectors and the sensor sockets with a good spray electrical cleaner, and them reconnect them.
If that does not solve the problem, then could be up line with a bad connection at the EBCM connector isntead.
One last thing, and if you are not running stock size tires on the rims, could be a problem with the size of the tires front to back causing the problem instead. The ECM is set up to read the hub speed sensors with the rear tires 1.04" larger in diameter (OD of the tire) than the front tires, and if the size percentage ratios are off, it going to reek havoc with the entire system reading the tires speeds correctly to begin with.
Also to point out, the steering wheel position sensor is directly plugged into the ECBM, as well as the Yaw sensor too, so problems with these connections or modules, will also kick the active handling if a misread as well.

**** man so much work. Why did it happen today it was perfect before. Today is chilly day. But the message comes after few kms so the car is already warm

There is a sticky at the top of the forum that has more (and yet less)info and answers than you ever wanted to know about the SAH issue.

If yes, then it's the summer performance tires not getting warm enough, and they don't have any type of grip. Hell, in the winter time, I switch from super sports to SPT, and still don't take the car out when it below 50f/10C since eve the SPT's tires will not get warm enough to have any real grip instead. Hence will end up not only into the ABS driving it normal like I do in the summer time during braking, but will end up just spinning the tires on normal starts from stop lights as well.
If you are sure that it not the tires loosing traction, then suspect that the cold if reeking havoc with the wire connection points instead.

Chilly as in under 50F/10C?

I don,t know about the C6 as I have only had mine a short time but I had the same error message on my 2003. It turned out to be the ECBM which I sent off for repair. This is a common problem on the C5 due to flaky solder joints. As I said, it is common on the C5 but I do not know about the C6 but maybe someone else knows?

There was a "service active handling" recall back in 2012 for some wires coming loose in the steering column from using the telescoping wheel feature. The loose wires were causing the message to appear.. You may want to check if your car was on the list, and if so, if the column repair was ever done....You never mentioned what year car you have...WW

Yep, scanning for the codes helps narrow it down some. I realize we are speaking of the C6 here, however the same message popped up on my C5 once. Remembering that I had read somewhere about this specific problem and the ground splice packs under the hood and in the area of the doors, I took those apart and cleaned up the connections. Hasn't had any TC/AH messages since.

Service active handling
This issue is caused by a wheel position sensor that is about to fail!
The fix is to replace the sensor which is on the steering column. This was a recall issue on some C6s but you don't state the year of yours. It is an easy and quick job but needs to be done by a Chevy dealer or real good mechanic that knows Vettes. Cost is about $300 if not on the recall list. Get it fixed as the problem will get worse. It has nothing to do with brake fluid level or cold tires.
Good luck!
