The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:Gauge or instrument faultWarning lightAir conditioning or heaterLights (headlights, turn signals)NoiseLoss of engine power, no accelerationSmoke or fireLeak

Record by record

107 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 held for a while1
  • says it came back1
  • says it did not fix it4
  • result not stated6

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 issuesSpeedometer needle appears inaccurate (specification +/- 2 MPH)1

  1. Manufacturer communication2003–2006 GMC YUKON ・ 2024-08-13(2 earlier editions of this document folded here)

    Speedometer Needle Accuracy Preliminary Information

    1. 1Fault

      • A customer may say the speedometer needle appears inaccurate.

    2. 2Finding the cause

      Possible causes

      • An instrument panel cluster with a physical speedometer needle drives the needle electrically with a stepper motor, and some variation in accuracy is possible.

      Steps to confirm (in the document’s order)

      1. Digital readouts such as the "Digital Speedometer" on the DIC read the Vehicle Speed Sensor (VSS) directly and are much more accurate.
      2. The specification for needle accuracy is +/- 2 MPH (= 3.22 km/h) at any given speed when looking straight at the needle.

    3. 3Correction

      This Preliminary Information communication provides information to the technician about vehicles that the speedometer needle appears to be inaccurate. Dealer should advise the customer the specification for speedometer needle accuracy is +/- 2 MPH (= 3.22 km/h) at any given speed when looking straight at the needle. Â

      What the documents say to do

      Speedometer needle appears inaccurate (specification +/- 2 MPH)

      Confirm

      • The needle accuracy specification is +/- 2 MPH (= 3.22 km/h) at any given speed when looking straight at the needle.

      Caution

      • Tire size, tread life and inflation may cause some variation in the readings.

    From the manufacturer’s document

    • Applies to：Applies to 2003 - 2024 GMC Yukon models (note: the years run later than the years this service covers).
    • Condition：A customer may say the speedometer needle appears inaccurate.
    • Cause：An instrument panel cluster with a physical speedometer needle drives the needle electrically with a stepper motor, and some variation in accuracy is possible.
    • Confirm：Digital readouts such as the "Digital Speedometer" on the DIC read the Vehicle Speed Sensor (VSS) directly and are much more accurate.

Known issuesVoltmeter fluctuates between 12 and 14 volts (Regulated Voltage Control, normal)1

  1. Manufacturer communication2005–2006 GMC YUKON DENALI ・ 2018-06-04(1 earlier editions of this document folded here)

    Voltmeter Gauge Fluctuation and Battery Charging Information

    1. 1Fault

      • Customers may comment that the voltmeter is fluctuating between 12 and 14 volts.
      • When towing or hauling a camper/trailer, customers may comment that the auxiliary battery for the camper/trailer will not stay charged.

    2. 2Finding the cause

      Possible causes

      • Starting with the 2005 model year, light duty full size pickups and utilities have a Regulated Voltage Control (RVC) system.
      • The RVC system reduces the targeted generator output to 12.6–13.1 volts in "Fuel Economy Mode" to improve fuel economy.

    3. 3Correction

      Repair

      1. With the tow/haul feature enabled, the RVC system stays in "Charge Mode" and the targeted generator output voltage is 13.9–15.5 volts, depending on battery state of charge and estimated battery temperature.
      2. The second method is to turn on the headlights, which increases the generator's targeted output voltage to 13.9–14.5 volts.

      Caution

      • This fluctuation with the RVC system is normal system operation and no repairs should be attempted.

    From the manufacturer’s document

    • Applies to：The model list names 2005-2014 GMC Yukon models.

      Possible causes

      • Monitoring devices and other electronic accessories such as aftermarket cruise control or police speed checking devices (RADAR or LIDAR) may cause one or more of the listed concerns.

      Steps to confirm (in the document’s order)

      • If normal SI diagnostics identify no root cause, check for a device plugged into the ALDL or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling.

    3. 3Correction

      Repair

      1. If the device is available, try to duplicate the condition, then remove the device to see whether the condition is eliminated.

    • Condition：The SES, MIL or CEL light may be set with numerous communication DTCs such as U0100, U0101, U186B and U1862.
    • Condition：The transmission may not shift for one key cycle, with the TCM in default mode.
    • Condition：Gauge readings may be erratic or displays may flicker.
    • Confirm：If normal SI diagnostics identify no root cause, check for a device plugged into the ALDL or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling.
    • Cause：Monitoring devices and other electronic accessories such as aftermarket cruise control or police speed checking devices (RADAR or LIDAR) may cause one or more of the listed concerns.
    • Caution：A device with a secondary DLC connector can be hidden out of sight with its harness, and the technician may not notice that the diagnostic connector is not in the factory location.
    • Repair：If the device is available, try to duplicate the condition, then remove the device to see whether the condition is eliminated.
    • Repair：If the condition is not eliminated with the device removed, continue diagnosing the vehicle with the appropriate Service Information.
