Question
2001 Chev. Blazer
Thank you in advance for taking my question. I am having no mechanical problems with my brakes functioning but when I jacked up the rear of my vehicle (to troubleshoot a drivetrain vibration) the ABS light came on and stayed on.
I actually put the vehicle in drive while jacked up and I think?? this set the code. My scanner does not read ABS codes. According to a repair manual that I have, there is a code when "the wheel speed differs from the vehicle speed by more than 10%" (CO238)
My question is can I reset the ABS? Disconnecting the battery and pulling the ABS fuse and the ECM fuse did not reset the light.
Thank you

Answer
might be able to clear it by disconnecting the battery, it is because you had the rear tires moving and not the front, so the system thought there was a fault with the front sensors not reading.  If that does not clear the code you might be able to get a local parts store to clear it for you with their scan tool
