2003 Chevrolet Corvette: ABS light or ABS activating

Filed Aug 31, 2016 · Brakes, Driver assistance · 72,000 miles · KY

The ABS control module has become non-functional. This eliminates the safety aspect of anti-lock braking, traction control, active handling, and anti-skid control. Chevrolet no longer supplies this critical element to my car's safety and performance. The digital information display center flashes that these safety elements need servicing, which is also a safety impairment because I cannot get any display of other functions of the car, I.e. Mileage, fuel warning, options, and trip information. The part number is 10343433 (ABS control module). This is an AC/delco number and none are in stock anywhere is the united states. I was told by multiple dealers that none are available and general motors will no longer supply this critical safety item again! This is a horrible support service on something so critical to the safety of a very expensive automobile. The response by general motors is selfish and uncaring. If you type ABS control module for corvette series c5 in google, you will find an unlimited resource of complaints. I believe this will be a series of accidents waiting to happen that will cause personal injury and death on our highways. Please investigate and take action.

The problem started as a highly intermittent warning that the ABS, traction control, and active handling suspension system needed to be serviced. It would usually go off by shutting the car off and restarting it. Couldn't locate the problem. This year when I took the car out it reset once and then stayed on. Diagnosed it, generated dtc error code c1214, indicating a bad power relay inside the ABS unit. The car now has just over 40,000 miles. To answer an obvious question, yes the problem did occur a few times while driving but it occurred primarily when starting the car. Searching the internet it seems that this is a common problem across a large range of gm vehicles using this specific ABS system made by delphi. It requires replacement f the ABS unit to repair.

While driving my 2003 chevy corvette at highway speeds the "service active handling" and ABS alert came on, no problems with driving or braking were initially noted, system will not reset, and I have noted occasionally while braking the ABS does seems to activate for no apparent reason during normal braking. If I deactivate the traction control the braking issue doesn't seem to be as recurring, but the alerts continue advising to service both systems. Taking the car into my local chevy dealer for repairs but from my research this appears to be a re-occurring problem with many corvette owners of various years, potential issues have been cited as the wire harness in the telescoping/tilt steering wheel and/or the electronic braking control module, (ebcm) are faulty. Some have reported serious accidents, however I suspect many have not reported the problem and/or have not experienced it yet because alot of vettes are low mileage. Seems this is a serious consistent problem that would trigger a national recall inorder to prevent future potential accidents.

While driving, my vehicle's warning system for the active handling & ABS system activates during normal driving conditions. It is highly unlikely that both of these systems would develop a problem at the same time. Upon researching this, I discovered that gm realized a flaw in the designing of the wiring harness that is contained within the steering column that is responsible. Gm has designed a part to fix this, but at the owner's expense. In these types of vehicles, the active handling & ABS is a safety feature, and I can only assume that whenever the warnings are activated these safety functions are no longer functioning as the computer believes that there is a problem with them when there isn't. The warnings do not come on at the time of start up, but only after driving the vehicle for about 5 miles. If there in fact was a problem with these features, a warning would come on at start up. Gm has found that the wiring harness becomes stretched from continued use of the telescoping steering column over the years which causes the false warnings. Other drivers have reported power steering failure and other problems associated with this. This is a design flaw that could cause drastic problems if the computer falsely disengages these features, especially the ABS during driving in the rain or snow. These vehicles rely on these systems for safe operations. Once the warning comes on, there is no way to check to see if the active handling feature is on or off, as the computer will not allow the system to be checked.

Abs tracking control light came on with a failure. It then went out. This happened a couple more times during driving in the next couple of weeks(car not driven that much). October of 2008, ABS light came on again and stayed on. Took car in to be serviced. Was told computer system was bad. Tried to locate a used system to save money. Was informed by chevrolet service department that could not use a used computer because of a known problem with the computer. Had to have replaced and reprogrammed ABS trac control module for $1490.80. Was told to hang on to receipt because could become recall.
