After having the fuel sensor card replaced, my c6 spent several additional days having the "Service Active Handling System" message chased--but no computer record as with other prior posts. Local service argued with GM and spent a lot of time checking connections and grounds. Thought the problem was solved for about 10 days--reappeared last night. Did not repeat after turning off engine and restarting. Any recent experiences with this?--would like to give some ideas to my local service folks who have been very accomodating.
had same problem with service traction control never no codes they said it came on because service fuel system came on after they replaced lines tank fuel card next day came on again when you turn off car code is cleared wntback complained three more times they hooked up tech 2 tester repededley 7 times in a row then 4 c0des came up the problem was abs module wasn't communicating with main computer it has to also contol active handling and they have no modules that work all updates suck will only download 40% of program have to wait three weeks to get one pulled from line that will go bad to but when I can get service traction contol to come on car is very fast
this is part of a response i had in another SAHS thread, hope it helps you...
took it in and they said "steering sensor" no problem well have it back in a day. well picked it up and never even got it into gear and it was on again. gave it back and it took a couple days but the serve writer said the steering sensor wasnt the problem but was a symptom, had to run some sort of extended test to find this to be the problem. part #89060341 f-module kit. service writer showed me it was the antilock brake module. its sits just under the power steering, has about a half dozen small metal lines running to it. got about 200 miles on her this weekend and no problems.
UPDATE!
i have since put 1500 miles and still nothing.
Last Tuesday was driving along the highway when "sevice traction control" message came up. 10 seconds later, the "reduced engine power" warning came on and I was left with a poorly running volks wagon to get me home. I took it to the dealer the next day and they hooked it up and said it was the accelerator pedal sersor module. Waited four days for the part to be shipped up and after it was installed, same damn thing. They're now testing all sirts of other things and in contact with GM Engineering. ....And I'm pissed right off.......
The car is only three weeks old and has now been in the shop for the last week and they don't have a clue what's wrong with it...........Any advice / suggestions would be appreciated......Thanks
