850 abs question

hi all. since the end of last summer, my 1995 850's ABS and TRACS warning lights have been switching on and off every now and then. based on what i've read on the forum it's the abs module, because the odometer also stopped working around february. i've been looking on ebay and other sites for a used abs module and most of them come without traction control. i'm wondering (since i don't want to shell out up to $500 for a new one) if i can use one without tracs on my car so that the abs and odometer will work again. any help would be appreciated

    You need to do some more investigating. The ABS units didn't fail until 1996!!

    You need to check the ABS fault codes before you buy anything.

    The odo failure is due to a plastic gear failure inside the panel. It needs to be replaced, and is fairly easy to do.

    You can get the actual mileage from the OBDII port and set the correct mileage before you put the odo back in.

      klaus-
      i do remember reading that the abs units started to fail in 1996 but my car seems to be victim of similar symptoms. the reason i'm not sure if the odometer gear is broken is because it used to stop working and then start again intermittenly but for the past few months it just hasn't started working again. any other ideas, or are you pretty sure it's the gear?

        The odometer gear is a common problem until 1998, when it went electronic. It is easy enough to remove the instrument cluster and look for a broken plastic tooth.

        The ABS module R&R is also easy and Victor does a very good job. You can drive the car without the ABS module, there just won't be a working speedometer while the unit is out of the car.
