ABS pump 850 1997

OK. So i took my unit off and sent it to victor last year. He fixed it, and sent it back. My abs light never went off and Ive been too lazy to look into it. Now that Im selling the car, Id like the light off. I took it to my local indie, and plugged in and said that the computer is reporting a stuck valve. Im assuming this means I need a new ABS pump.

I am also assuming this is an expensive dealer piece.

Should I trust pick a part?

How easy is the job to replace the pump?

    Did your indie reset all the codes and then let you drive and then check the codes again?? Because you state that the ABS light was never reset from when you changed the pump the first time...

    I tell you this because on my 1994, you have to reset the ABS system and in order for it to leave diagnosic mode and turn off the ABS light you have to get the car to above 25MPH with all systems GO.

    The dealer will ask $2000 for a new ABS pump. Junk yard time, and/or rap it with a plastic hammer a few times????

      Steely: I've disconnected the battery several times (to clear CEL, lol) Wouldn't this reset any codes?

      Klaus: I saw 3 at my local pick a part a couple of weeks ago, and I thought about getting one. I know what I'm doing this afternoon! Do you think they will take my wallet for a ride with the used part as well?

      Id say out of 5, Im a 3 star mechanic, so I think this is do-able. Also, there was a unit attached to the 97 at the yard, Im thinking about snatching that up too!

        Disconnecting the battery on the '84 did not reset the codes for the ABS. You have to reset and then go driving. Not sure if this sequence holds true for the '97. Anyone???

        Steely is correct about turning off the ABS light, all of the codes need to be cleared AND the car driven over 18mph - the system self tests, then if the light stays on the code will be stored again.
        My 1995 had a pump CEL because the pump got drenched. After clearing the codes, the ABS light went out as soon as I got to 18mph because it all worked again.

        In your case, get a new unit. You don't need to tell the P&P what the dealer cost is for a new one. But get the entire unit, including the ABS module; it is easier to remove that way.

          So disconnecting the battery won't clear an ABS code? Im confused!

            The ABS, ECC, and other modules contain their own memory. They are not affected by power loss. Clearing the codes in the ABS unit will not tturn off the ABS light until the car reaches 18mph, when the self diagnostics are performed. Of the self-check does not detect any errors, then the ABS light will turn off.
