    Speedometer quits working

    We have a 1999 Catera and are having some electrical problems.
    When we start the car up in the morning the check engine light is on. Every thing seems to be working correctly. Runs good. After a little while of driving the speedometer quits working and the ABS and Traction Control light comes on. When this happens it is also hard to steer. The codes that come up are
    U2108 - CAN Bus Error ABS
    U2108 - Lost Comm with ABS Control System
    DTC P1700 Transmission Control Module

    If we let it set for awhile when we start it up the ABS and TC lights are off and the speedometer works but after driving for awhile the speedometer quits working and the TC and ABS lights come on.
    Any suggestions on how to fix this problem are appreciated
    Thanks
    Jeff

    Re: Speedometer quits working

    Because the speedometer isnt working and you get the TCS/ABS light , it could be related to the Vehicle Speed Sensor which also works with the ABS system and of course, the speedometer. A link may be broken there, sensors bad, or the TCS/ABS module is having problems calculating both.


    What do you mean by hard at steering when this happens? Does it feel like the powersteering has been cut off or...?

    When the speedometer quits it gets hard to steer. I was thinking that maybe the powersteering was speed sensitive. The power steering seems to be working but it is very hard to turn.
    Thanks

    Re: Speedometer quits working

    Hi,
    I am new to this group but I am having the EXACT same problems as the other person. Sometimes the car works fine but 90% of the time the speedometer cuts in and out and the ABS, TC and check engine lights come on. My computer would not give a reading at all. But the speed sensor has been checked and appears to be working properly. Any other help that can be given.

    Re: Speedometer quits working

    There is a module that controls the ABS and Traction Control services- this goes to the transmission and the engine management. When its doing that all at once-in your case... id say it lost communications between one of those sources(it runs on a network). What do you mean by your computer? A code scanner i presume? Check the history's. Otherwise, its an electrical issue between one of these sources.

    While your at it, are there other lights that come on? And when does it happen? What are the battery volts reading from the dash readout?

    Hi,
    Thanks for the quick reply. No other lights come on so far and the other problems that I mentioned are very intermittent. They just come and go on their own. No telling when! Let me know if you have any other suggestions.


    Thanks,
    Sean

    Re: Speedometer quits working

    I have a 98 catera and I am having the same problems. The car has gone to 2 seperate mechanics and it was just at the 2nd Cadillac dealer to try to repair this problem. I have over $700 invested into this problem and the best anyone can tell me is they don't know what the problem is. Is there anyone that knows what this ABS, Traction Control and Speedometer problem is?

    Re: Speedometer quits working

    There is not an error code comming back it just looses communication. This past time they said they performed 3 different diagnostic checks and nothing came back. When the lights come on they lose communication. Now they say they can check further but they are not sure what it will cost but the service writer said it should be about $1500. But that is an estimate with no knowledge behind it. This seems to be a common problem, someone should know something.

    Re: Speedometer quits working

    It may be the vehicle speed sensor(s) in the transmission. Since the ABS and Traction control system utilize this also as a point of referance, if that malfunctions so does the ABS and TC. The vss (and the components related-speedo gear, and speedo wheel) is not an uncommon problem- but rare in some senses. Usually just the sensor assembly itself, not the speedo gear and/or wheel.. otherwise you'd need to get the transmission overhauled.

    It would be a direct source of the problem if the ABS and TC arent malfunctioning. From the tests that the dealer did, im guessing those systems arent bad.

    #17 is the VSS.

    Hi
    I'm also new, in fact I've registered Becasue I have the same problem. The local dealer couldn't fix the problem: ABS/TC lights, then Speedometer, then the power steering goes off.


    Can anyone please tell me if changing the speed sensor solved the problem or not? and how much did it cost?

    Thanks a lot.

    I am going to replace the speed sensor this weekend. I am just waiting for the part to come in from Cadillac. I will keep everyone updated if this solved the problem or not.

    I am unhappy to say that replacing the vehicle speed sensor did not work.
