Record by record

4 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

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.

SUSPENSION1

  1. Manufacturer communication2001–2006 GMC YUKON DENALI ・ 2023-12-26(3 earlier editions of this document folded here)

    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).

      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.

      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.
