Continuous problems with 02 ZO6
I have had this car for a week now and it has been in the shop 3 times for the same problem. The problem is that for no reason the DIC will say "reduced engine speed, service traction sys, service active hndlg." They have had my car at the shop and checked over all related parts and found nothing wrong. Has anyone had this experience to tell me what the culprit was. I got a lead that it might be the wheel speed sensors loosing communication with the computer which would cause this, but, any other help would be appreciated. In a week I have had a Neon, Buick, and Echo, rather than my car and it is getting very annoying. :mad :mad

Re: Continuous problems with 02 ZO6 ('97 C5)
Does yours do it every 30-60 miles or so??? That is how often mine does it and obviously it is not safe to drive the vehicle when it can slow itself down at will.

Re: Continuous problems with 02 ZO6 (Hater)
Sounds like a BCM (Body Control Modual) problem. Ask the service wrighter to have the tech replace the BCM unless they can prove it to be something else!

Re: Continuous problems with 02 ZO6 (Hater)
In order to have an idea as to where to start looking for the problem, you need to check the DTC codes. If you don't know how then this will help: http://www.c5forum.com/ayc/dtcdic.php
Post the codes and we might be able to help :yesnod:

Re: Continuous problems with 02 ZO6 (SFVetteman)
If you lost a wheel speed sensor you would get messages from the ABS, TC and AH systems but the engine power would not be reduced. Engine power can be reduced when certain TC conditions exist. If there is an extraneous signal on one of the wheel speed sensor lines or if the EBTCM module has a problem the EBTCM may be signaling the PCM to cut power just as it would if TC was activated when the wheels spin. Things to check are all of the connections for the wheel speed sensors, the EBTCM and its wiring, the PCM wiring, etc. If this is intermittent it can be a real bear to find since probably every time you take the car to the dealer it will be working just fine. The best mechanic can't fix something that isn't broken at the time.

Re: Continuous problems with 02 ZO6 (Hater)
This is maybe a long shot but I'd think that when you switch active handling off, the problem should disappear if it was caused by the wheel sensors/ABS system.
Hope this helps

Re: Continuous problems with 02 ZO6 (Hater)
I was messing around with my PCM with a LS1 edit program and unplugged it,
when I should not of messed with it while "reading". afterwards the DIC went nuts and said exactly what yours read, but it went back to normal after some driving. So I would think that there is nothing wrong with any hardware, but it's a computer problem only.
Just my 2 cents worth.

Re: Continuous problems with 02 ZO6 (Hater)
Have you checked your battery as a possible culpret. You might have a leak and not even know it! You can find out real easy by pulling the right front tire abd removing the AFT lower wheel section panel that allows access to your TCMand BCM. It will allow you to see if you have any abttery acid leaking down the frame and onto these componets. Just a thought. Ihad a leaking battery and didn't even know it until I pulled this panel and seen the damage itcan cause. It's a whole lot easier to remove this panel and look for a leak coming from above, than pulling that heavy **** battery out!
Just my two cents.

Re: Continuous problems with 02 ZO6 (Hater)
check the main cannon plug on the side of the active handling/traction control module next to the radiator. I did some work on my car and afterwards i was getting the traction control codes and it ended up being that i apparently bumped that plug a little loose and once it was reseated, the problem was gone. as for the reduced engine power, not sure.

Re: Continuous problems with 02 ZO6 (Av8ter)
Well, it turns out that there are 3 computers in the front passenger fender well, one of which has one (1) pin that is loose in a molex plug. So far, they, are ordering new connectors and plugs. They have done what they can to solve the problem because it will take up to 2 weeks to get the parts. So, thanks for all of your input because some of you were dead and I do appreciate it.
