    99 El Dorado ABS/Traction Control Lights On

    Hi,
    My 1999 El Dorado has had 2 warning lights running for months now, the ABS and Traction Control. They came on together. I ran the codes and 2 current ones came up:
    C1226, Right Front Excessive Vibration; C1233 Right Front Speed Circuit Open or Shorted.
    Any ideas on where to proceed next to solve this issue? My back yard mechanic thinks it is a computer issue related to the ABS system, I'm not so sure, thats why I'm here!
    Thank You.

    My spidey sense says to check and clean the elec connections around RF wheel and on EBCTM. If they are fine the hub is prob bad. If you were getting a bunch of other codes you could consider EBCTM going out.
    What other codes did you have history?

    Yeah, it's wheel speed sensor related, not a computer issue.

    Re: 99 El Dorado ABS/Traction Control Lights On

    Thank you for getting back to me so quickly! I got lots of codes under "History", in order as seen on dash:

    P1574, B1552, B1983, U1255, NO ACM, U1255, B1327, C1222, C1226, C1233, C1291, B1552, B15558, B1983, U1255, U1064, NO RFA, NO CCP, B0856, B1983, U1300, NO NMM CODES.

    The most interesting seem to be:
    C1222 - Right Ft Speed Sensor, B1558 - BCM EPROM CHECK ERROR (?), U1255 - Class 2 Communication Malfunction, U1064 - Loss of Communication With DIM

    Is that any help?

    The others don't mean anything without their definitions, but B1327 is a low voltage code. Low voltage can cause false/random codes.

    What's your voltage readout with engine OFF? Preferably after being off for at least 30 minutes.

    The voltage after sitting for 4 hrs was 11.6, after I started it the voltage read 13.3. The head lights stay on for a minute for some reason after shut down, that can't help.

    A healthy, fully charged 12 volt battery, will produce ~12.6 volts. ~12.0 is essentially dead. Have the battery charged and load tested, it will almost definitely fail.

    Your car has automatic headlights, as well as an adjustable delayed off feature, twilight sentinel (to provide light as you walk from your driveway, to your house, for example). You should read your owners manual, front to back, at least twice.

    OK, I'll replace the battery, good place to start. I'll also check the right front wheel and EBCTM
    connections. Once done, can I clear the warning lights?(and hopefully) they will stay off.
    Thank You for your help!

    Yes. After a new battery clear the codes and see what returns. If the C1226 & C1233 back again, it's time to replace the RF hub & bearing assembly.

    Re: 99 El Dorado ABS/Traction Control Lights On

    All of the above codes with the exception of the RF wheel speed sensor can be caused by a weak battery. However the 2 codes related with the wheel speed sensor not, I see you in the near future replacing that wheel hub. The Headlamps thing is as simple as adjusting the slider underneath the headlamp switch from ~3 min (all the way to the right) to off (all the way to the left). Also the headlamps are among the largest power consumers. It really does not help at all with your weak battery situation leaving them on for long with engine off.

    Cool Re: 99 El Dorado ABS/Traction Control Lights On

    I really dont think you need a new battery.
    I can say with 100% purity that you have a bad r/f hub hearing assy.
    I purchased mine for roughly $110 (for a GOOD quality one from Summit Racing)
    takes about 45 min for the average mechanic to install.

    He has loss of communication codes, lots of codes in history, low voltage codes, and LOW VOLTAGE FROM THE BATTERY. The battery's toast.

    Should the dash read 12+ volts with engine off? Mine does not. Never has. Always has read 11.5 or so

    A healthy battery produces ~1 full volt more than that, and the dash should reflect that. Dirty connections maybe?

    Re: 99 El Dorado ABS/Traction Control Lights On

    Curiosity got the best of me. Went out to check mine. At key on, engine off (auto headlamps off) I got 11.8 on the DIC. I then used a DVM with key off, engine off. + lead on the + cable under the hood at the jumper cable connection and the - lead on a good ground. That way I got 12.3. Obviously there is too much draw at key on, engine off to be accurate on the DIC readout.
