Record by record

14 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed2
  • says it held for a while1
  • says it came back2
  • says it did not fix it5
  • result not stated12

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesUnwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)12

  1. Recall2000–2002 GMC YUKON ・ —

    ABS activation recall in pickup trucks and SUVs

    1. 1Fault

      • Corrosion may occur between the front hub/bearing assembly and the wheel speed sensor; if the brakes are applied at a speed greater than 6 km/h (3.7 mph) but less than 16 km/h (10 mph), the corrosion may cause an unwanted ABS activation.
      • If this occurred where stopping distance is limited, a crash could occur.
      • The condition does not set any ABS codes and does not illuminate the ABS warning lamp.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. Check the mounting surface on the sensor head for flatness against a metal machinist's scale or other straight edge, in multiple positions/directions (minimum 3).
      2. With the bearing rotated at about one revolution per second, the reading should be at least 350 ACmV; if it is less than 350 ACmV the wheel speed sensor must be replaced.

    3. 3Correction

      Repair

      1. If the mounting surface on the sensor is warped or bent, the sensor must be replaced.
      2. Thoroughly clean the wheel speed sensor mounting surface on the bearing hub with a wire brush, sandpaper, emery cloth, scotch brite or equivalent to remove any rust or corrosion.
      3. Spray two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) on the complete sensor mounting surface on the bearing hub, letting it dry between coats.
      4. When the corrosion inhibitor is dry to the touch (about 10 minutes), apply a light coating of the specified grease to the complete sensor mounting surface on the bearing hub and to the sensor and O-ring.
      5. Tighten the wheel speed sensor mounting bolt to 18 N·m (13 lb ft).

      Part numbers printed in the document

      The numbers are as the document prints them. The name and the replacing number are what the pages of GMPartsGiant, a reseller of genuine parts and not GM, state. Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • Remove the sensor by pulling it straight out of the bore; do not pry it with a screwdriver or other device, because prying will break the sensor body off in the bore.
      • This revision changes some breakpoints and adds vehicles that have moved into the severe corrosion areas; copies of bulletin 05068B, issued April 2006, are to be discarded.

    Cause
    CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.
    Remedy
    DEALERS ARE TO REMOVE THE WHEEL SPEED SENSOR AND THOROUGHLY CLEAN THE WHEEL SPEED SENSOR MOUNTING SURFACE ON THE BEARING, APPLY RUST INHIBITOR TO THE CLEANED SURFACE, GREASE THE MOUNTING SURFACE, REINSTALL THE WHEEL SPEED SENSOR, AND CHECK THE PEAK-TO-PEAK OUTPUT VOLTAGE TO ENSURE THE WHEEL SPEED SIGNAL IS WITHIN SPECIFICATIONS.
