Record by record

15 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.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed2
  • says it came back1
  • says it did not fix it1
  • result not stated8

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)9

  1. Recall2000–2002 GMC YUKON ・ 2004-11-05

    ABS activation at low speeds in Canadian Atlantic provinces

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

      What the documents say to do

      Unwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)

      Confirm

      • The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.

      Repair

      1. Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
      2. The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.

      Caution

      • Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.
    Read the sentences of the record
    Cause
    Certain vehicles located in Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador may experience unwanted Antilock Brake System (ABS) activation and increased stopping distances during low-speed brake application (less than 16 km/h and greater than 6 km/h). This condition does not set any ABS codes nor does it illuminate the ABS warning lamp. Correction: Dealers will remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply Zinc-X to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the output voltage to ensure the wheel speed signal is within specifications.

Known issuesBrake pipe (brake line) corrosion and rupture2

  1. Owner complaint2006 GMC YUKON DENALI ・ 2017-09-08

    Severe brake line corrosion and wheel speed sensor corrosion causing ABS activation at low speeds

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

      What the documents say to do

      Brake pipe (brake line) corrosion and rupture

      Confirm

      • In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).

      Repair

      1. GM recommends replacing the entire set of pipes whenever any pipe leaks or is corroded enough to need replacement.
      2. On June 28, 2013 GM released 66 new part numbers for servicing brake pipes in 1999-2007 GMT800 pickups and utility vehicles.

      Caution

      • Analysis of repair records indicates that consumers often elect to repair only the failed circuit.
