RESPONSE<\/p>\n
The most common reason would be from a failed door ajar switch(door open warning lamp switch). The switch is located on the door latch assembly.<\/p>\n

System responds to door ajar switch as follows:
\n\u2022The generic electronic module (GEM) uses the door ajar switch input for two different rear air suspension system functions:
\n\u25fepreventing vents when a door is open to avoid the possibility of the vehicle lowering and the door catching on an obstruction.
\n\u25feservicing a correction immediately, if needed.
\n\u2022The liftgate and both front door switches close to ground when opened, while the sliding door switch provides ground when closed and opening the door provides an open in the circuit.
\n\u2022The GEM can sense each door (open or closed) independently.
\n\u2022If a damaged door ajar switch (door always open) condition exists, the GEM will interpret that a door is open and not vent unless vehicle speed is above 24 km\/h (15 mph).
\n\u25feAbove 24 km\/h (15 mph) the GEM disregards all door signals.<\/p>\n","protected":false},"excerpt":{"rendered":"
