Supersession Statement
This PI was superseded to update Model Years. Please discard PIC5815C.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this
PI.
Condition / Concern
Some customers may comment that their vehicle is sitting low after being parked for several days or
more. Technicians may complete normal diagnostics for Air Suspension Air Leaks or Low/Uneven Trim
Height with no trouble found.
Recommendations / Instructions
It is important to note that, under normal conditions, it is typical and acceptable for the air
suspension system to drop slightly over time. Changes in temperature can affect trim height as
well. The trim height can be expected to drop as much as 2.6mm per every 10*F drop in ambient
temperature.
If a customer states that their vehicle loses trim height when parked and unused for several days
but achieves and maintains normal trim height when cycling the ignition and using the vehicle
regularly, this should be considered normal operation and no repairs should be attempted. In this
situation, the technician would expect to find no leaks or air bubbles when testing with soapy
water.
Dealers can remind customers that cycling the ignition or starting the vehicle will bring the trim
height back to normal levels.
Customer Information
Please communicate to the customer this condition is a normal operating characteristic of their
vehicle. It will not impact the designed performance or reliability of the vehicle. Please share
this information with the customer, including a copy of this message.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition
exhibited is resolved without completing every step, the remaining steps do not need to be
performed.
