How it is said to have ended

  • says it was fixed2
  • says it held for a while5
  • says it came back7
  • says it did not fix it8
  • result not stated31

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)3

  1. Recall2002 GMC YUKON XL ・ —

    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).

Known issuesHigher than expected oil consumption at 8600 GVW and above (accepted rate and consumption test)1

  1. Manufacturer communication2001–2006 GMC YUKON XL DENALI ・ 2025-01-17(1 earlier editions of this document folded here)

    Oil Consumption Measurement and Loss of Oil Service Bulletin

    1. 1Fault

      Not stated

    2. 2Finding the cause

      Possible causes

      • Towing a trailer or hauling additional weight will increase oil consumption.

      Steps to confirm (in the document’s order)

      1. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is stated as 1 liter (1 qt) within 400 liters (100 gallons) of fuel used.
      2. Inspect the oil pans, engine covers and the engine oil cooler for leakage, and inspect for oil leakage into the engine coolant.
      3. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to the PCV system can result in increased oil use.
      4. Wait at least 15 minutes after the engine is shut off before checking the oil level, so most of the oil has drained back into the crankcase.
      5. Check the oil level and record the vehicle mileage, date and exact oil level on the bulletin's form, then make sure the oil level is at, but not above, the full mark on the dipstick, adding oil if necessary.

SEATS AND RESTRAINTS1

  1. Recall2001–2002 GMC YUKON XL ・ 2002-04-11

    Seat Belt Retractor Sensor Inoperative Recall

    1. 1Fault

    2. 2Finding the cause

      Certain vehicles fail to conform to CMVSS 209, seat belt assemblies. These vehicles have a condition where one or two sensors in the driver's and front seat passengers seat belt retractors may be inoperative. The seat belt retractors will lock when the belt webbing is extracted during a crash; however the mechanism that locks the seat belt retractor when the vehicle decelerates quickly, such as during heavy braking, may not restrain the occupant as intended during a crash, and could result in injury to the occupant. Correction update: None required as no effect on vehicle safety. See recall 04-158.

SUSPENSION1

  1. Manufacturer communication2001–2006 GMC YUKON XL ・ 2023-12-26

    Suspension Service Communication

    1. 1Fault

      • Condition 1 (2009 or prior vehicles): a Service Suspension System message on the DIC with incorrect rear ride height, and DTC C0696 or C0711 set in the Electronic Suspension Control (ESC) module.
      • Condition 2: a Service Suspension System message on the DIC, possibly with low rear ride height under a heavy payload, and DTC C0711 set in the ESC module.
      • Condition 3: a loose hose hangs down at the left rear; upon inspection the hose may be found damaged or disconnected from the air inlet filter of the auto leveling suspension air compressor.

    2. 2Finding the cause

      Possible causes

      • Condition 1 can be caused by the wiring to the automatic level control (ALC) pressure sensor being shorted to ground.
      • Condition 2 may be caused by an internal fault in the ALC pressure sensor, which can occur when moisture gets into the sensor.

      Steps to confirm (in the document’s order)

      1. The air compressor assembly may have to be removed to see whether the wiring is pinched between the compressor assembly and the frame.
      2. If system pressure at start up is below 10 psi (69 kpa), the system runs the compressor to add air to the shocks as a replenishment cycle.

    3. 3Correction

      Repair

      1. For condition 1, repair any damaged or shorted circuits and reposition the wiring so it is not damaged again when the compressor assembly is installed.
      2. The sensor is no longer serviced separately; to replace it, install a complete air filter, dryer and sensor assembly.
      3. For condition 3, replace the auto leveling compressor air inlet filter and hose assembly (PN 22197160).

      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.

      Parts

      • Vehicles built before May, 2012 need a jumper harness for the updated sensor, which is included with assembly PN 22964558; vehicles built in May, 2012 and later need no jumper harness and use PN 22941807.

      Caution

      • Do not replace the complete air compressor assembly for this concern.
      • Condition 4 (no compressor self test at start up): the automatic level system normally does not, or only very infrequently does, cycle the compressor at key up.
