ssheen Posted November 26, 2005 Report Share Posted November 26, 2005 Hi, My wife's car, 94 Oldsmobile Cutlass Supreme SL is having ABS problems. The pads and calipers are new. The ABS seems to come on at times when it should not is the best way to describe the issue. How would I go about disconnecting the ABS? Any ideas on why it would be doing this?

Crazy K Posted November 26, 2005 Report Share Posted November 26, 2005 PHANTOM ABS it is normally the result of a poor signal from a sensor. As the wheel slows the signal drops away and is lost. You can pull the abs fuse to stop it from happening, this disables abs and leaves you with normal brakes. But I recommend fixing the problem. It could be casued by resistance at a dirty connector. Try disconnecting each connector, cleaning them, and putting some dielectric grease on the metal tabs before snapping them in place. See if this corrects your problem. and give us an update on what you do. If it still happens,it can it be determined which wheel sensor is at fault I'd have the sensor replaced. - Ken Quote Link to comment Share on other sites More sharing options...
birdman Posted November 26, 2005 Report Share Posted November 26, 2005 the sensors come off real easy, one bolt i think and are fairly cheap too. Quote Link to comment Share on other sites More sharing options...
ssheen Posted November 27, 2005 Author Report Share Posted November 27, 2005 Thanks for the input guys. I will try to clean the connectors and see what happens. Is there anyway to tell if the sensors are bad which one? What other years and cars are the sensors on? I can go pull some from my local u pull yard.

Crazy K Posted November 27, 2005 Report Share Posted November 27, 2005 One other thought.... I have sometimes seen a car run without brake pads, and doing so grinds the rotors and everything leaving a coating/deposit of powdered steel (aka rust ) all over everthing, including the sensor area. (aka my 95 Cutlass Supreme, no pads at the time of purchase!) I believe this can interfere with it's abs signals too! If you have a digital multimeter in the ohm setting, you could connect it to the abs sensor and slowly turn the wheel and compare the wheels to each other to see if one of the sensors is less responsive. but that would be a hard judgment call. Best to do is clean the sensors first, ensure no rust deposits are inhibiting the sensors and test drive, then let us know! - Ken Quote Link to comment Share on other sites More sharing options...

ssheen Posted November 27, 2005 Author Report Share Posted November 27, 2005 What other cars and years would have the same sensors as the 94 Cutlass Supreme SL? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted November 27, 2005 Report Share Posted November 27, 2005 Basically any Grand prix(up to 96), regal(up to 97), lumina(up to 99) Monte carlo(up to 99), or Cutlass supreme(up to 97) with ABS will have the same sensors. (a good junkyard would know) Again, I would attempt to clean the sensors area of dirt/rust, and clean and grease the ABS sensors's connector first...(oh, watch for any damaged wires too.) before you start just replacing parts. - ken Quote Link to comment Share on other sites More sharing options...
