C5 Corvette Active Handling Fix

Welcome to 4K Motoring!
After several attempts at fixing the Active Handling System Error on our 2001 Corvette, we finally found something that worked. Using our BossCom IF745 OBD2 Diagnostic Tool, we were able to fully test and flush our EBCM (ABS Module). We have not had another problem since! Add in some new ACDelco Performance Brake Rotors and Powerstop

I’ve been dealing with this problem for about six months. I sent the unit out for repair and it’s still doing it. The last thing I need to do is check the grounds and watch this video.

[@bman20233]

Nice video. I fixed my tcs and abs error issue by replacing all the TPS sensors. Havent had tcs or abs warning lights come on since these have been replaced

[@stevieanderson7281]

Great 👍 job

[@mwdunn3]

Great video. Glad the fix was just a fluid flush.

[@4KMotoring]

As am I! These things can be nightmares to troubleshoot

[@RicheySynthetics]

With The scan tool Is it self explanatory as far as the walk-through on how to do the flush ? Thanks for the informative video. 👍🏻

[@4KMotoring]

Pretty much, you just select the manufacturer, select the vehicle system you want to test, then let's you play with running the ABS pump and all the individual inlet/outlet valves

[@sherryswisher8911]

Rotor is not warped. It is either rotor thickness variation or you needed to bed the pads in. The brake material is not coated even on the rotor. Rotors don’t warp.

[@4KMotoring]

Well, this is at least the second set of pads on these rotors, with the current set having about 15k miles on them before the vibration started. Whether it's true metal thickness variation, irregular heat treatment, or the more likely irregular deposition of pad material, there was enough of a change in rotating thickness to induce vibration. For simplicity, most humans call that "warping"

[@sherryswisher8911]

Also use better pads. EBC or Hawk. The rotors do not out gas pads as modern pads do not out gas. They will clean the pads of dust and water.

[@4KMotoring]

For street use, the power stop Z28 formula is pretty good. I've run EBC in the past with good results, but would really look hard into mechanically adhered friction material if I was tracking the car more frequently.

I have a 2001 C5, what sizes are the C6 wheels and tires?

[@4KMotoring]

Rims went up one size from stock, 18" front 19" rear (rear backspacing is a bit different), tires went to a 245 wide front and 285 wide rear

[@alanpatterson9937]

@@4KMotoring Thank you!!

[@nyccorvette]

i had to clean my grounds that the EBCM was connected to.

[@4KMotoring]

Always a good move! I tried that initially with no luck
