H2 air suspension compressor pulses 5 times when key is turned on, then does nothing. There is no air in air bags

Hello and welcome to just answer. The air compressor will pulse and turn off if trouble codes are currently set in the suspension control module. This feature keeps the compressor from running constantly and burning up. The truck likely has a large air leak or a failed position sensor. You will need to have the trouble codes retrieved from the suspension module to diagnose.

How can I clear the codes
Expert:  David H replied 2 years ago.
That will require a scan tool to access the suspension control module. If the problem persists the codes will reset right away. Most all shops and mechanics have quality scan tools.
