    Troubleshot this and found the rear lh speed sensor wire harness had been broken. I replaced the wire harness and drove the car for a couple days to see if the error light would clear. It did not clear and so I tried disconnecting the battery for about and hour and reconnected. It still did not clear. Is there some way to clear the error lights without the use of a scanner or techstream?

    Thanks,
    Roger

    First you need to find out why those lights are on. Could be the thing you fixed, could be something else.

    If you don't have a scan tool that can show you what the trouble codes are, you can find out this way:

    Are you sure it's fixed? Maybe another sensor is bad? Or has wiring issues.
    You should get a scanner that will read the ABS system and find out what the issue is.

    Got abs problem fixed. Turned out both the rear sensors cables were cut. After I replaced the right side harness the code cleared within one block of driving the car. I believe I have a critter that chewed through the cables.
