    traction control issues

    So today when I drove my eldo after 3 weeks of being parked in the garage, it started acting very weird.
    After 5 mins of driving. When we stopped at an intersection, I pushed down on the gas pedal, it made a wieerd sound and it was slowed down like the tc thought we we were on ice. (Like something was knocking from the front.) I looked at the DIC it said traction restored. This happened to me 7 more times. I will check the codes tomorrow but I have no idea what happened....
    It said either: traction restored or traction enabled.

    ----------

    After the sound stopped it said traction restored. So does this mean the traction control interferered when I was driving... but I'm in California it was completely dry today about 85°.

    Re: traction control issues

    can you say $$$, what you descried sounds like unwanted Anti-Lock activation. Yes, codes would be very helpful here.

    The TCS engaged when it shouldn't have, not the ABS. Probably just a failing hub assembly.

    Have you pulled the codes?

    Re: traction control issues

    Yeah, basically the car sensed a skid that wasn't there. If it was while stopping I would think is was ABS. Either way, like MC said, most likely a failed wheel sped sensor (not terribly expensive). The DTC's will tell.

    Re: traction control issues

    Ok so i just pulled the codes here they are:

    DTC B1348 Very Low A/C Refrigerant Pressure HISTORY
    DTC B1350 Engine Coolant Over-Temperature HISTORY

    DTC C1223 LR Wheel Speed Sensor Input Signal is 0 HISTORY
    DTC C1224 RR Wheel Speed Sensor Input Signal is 0 HISTORY
    DTC C1226 RF Excessive Wheel Speed Variation HISTORY

    DTC U1255 Class 2 Communication Malfunction HISTORY

    These are the same codes from 3 weeks ago but my ABS light and traction warning light were OFF this time. Im stumped on this car.

    http://www.cadillacforums.com/forums...dirty-cat.html

    ----------

    These are the SAME codes from 3 weeks ago. If the computer picked up a recent fault code would it be added to the other codes? Or it wouldnt show until i clear all of them?

    Re: traction control issues

    Hard to believe 3 out of 4 W/S sensors could go at the same time. I'd be looking for something common to all of the. U1255 may be a clue.

    This Saturday I'm taking it to get a a/c recharge. While I am there, I will make sure I get to the bottom of this issue.

    ----------

    Oh and to the u1255 I guess he just yanked out the cable without turning the ignition off.

    Re: traction control issues

    Ok we just came back from the car wash ( just got new license plates and tags have came in) we just got the car insured and we can drive it on the road. And i cleared the codes before i drove the car.

    So when we were driving back from the car wash at a red light, we noticed that the traction control kicks in on low speed when pushing down lightly on the gas pedal, but once we give it more gas the traction control turns off. Once we pulled into the drive way i saw the traction light and ABS light were on.
    I pulled the codes while the car was on, and got these:

    DTC C1226 RF Excessive Wheel Speed Variation CURRENT ( this code has always came up after the brake got stuck couple months ago... I have a thread about that also.
    DTC U1255 Serial Data Line Malfunction DTC HISTORY

    ^^^ im guessing that cant be good.

    ----------

    wait there are 2 definitions for U1255????????

    DTC U1255 Class 2 Communication Malfunction
    DTC U1255 Serial Data Line Malfunction

    Re: traction control issues

    Your wheel sensor is most likely bad, time to change it

    Could try checking the alt and battery may be a low voltage gremlin. If it was one I'd say try checking the plug from wheel sensor but 3 hmm. I had same issue as you abs for no reason some electronic cleaner then dielectric grease on LR plug fixed it luckily.

    Did your traction control and ABS light come up after driving for 10 mins? Im going to check the front right speed sensor, thats the only speed sensor throwing a code now.

    Re: traction control issues

    Could a bent caliper(RF) cause the brake pad to rub on the rotor, causing it to slow down? or should i get a new wheel speed sensor and hope it works? if one wheel is slower than the other could it cause the traction control to come in?
