      Lite came on Friday PM .

      Best I know , there is one sensor on the RF hub / steering knuckle , on on the LF and one on the differential .

      What can I do to check the system ? Was told you can short 2 pins on the OBD connector & it would flash codes . I have done this on Service Engine Soon lite for engine codes . Never on ABS codes .

      Can not locate my manual / reference material . Help please !

      Thanks , 🙂

          Saturday , I got out the turkey baster & evacuated the brake fluid from the 2 compartments of the master cylinder reservoir . Wiped out the dark sediment from the 2 compartments & refilled them with fresh / new brake fluid .
          Drove it off and on over the weekend & it showed some improvement . Last couple of times I drove it , the ABS lite did not come on .
          Tried the diagnosis shown in the video , but by then the ABS lite was not on , and I suppose the codes are erased when you turn off the ignition .

          Thanks , 🙂
