Helpful Expert Reply:
I reached out to AirLift to see what could be going wrong with your Air Lift WirelessAIR Compressor System part # AL74000. They informed me that the A-09 code is a low voltage code. With this issue you want to check all of the connections on the system and most importantly ensure that both the positive and the negative connections on the wiring harness are connected directly to the battery terminals and not connected to any other power source or ground source.
Once you have confirmed this if it is still not functioning properly please let me know.
