If the controller for your Air Lift WirelessAIR Compressor System # AL72000 is showing a FAIL message then that typically means you have a blockage or leak in your system OR the controller is having difficulty talking with the rest of the system.
Start off by inspecting your compressor and air lines to make sure everything is in order and then perform the soap test where you put soapy water in a spray bottle and spray your air lines and bags to see if any bubbles appear - which would indicate a leak. For a block you'll likely need to replace that part of your hose using part # AL73RV.
If you don't find anything wrong try to join the controller with the manifold:
Set the manifold into join mode.
• Ground the join wire in the electrical harness.
• Locate the YELLOW join wire with heat shrink on the end in the harness.
• Remove the yellow wire from the cap leaving the cap atached to the
harness.
• Attach the exposed terminal to a good frame ground.
Cycle power to the manifold.
• Manifold will boot in join mode and will click the exhaust solenoid 5 times fast,
then 1 per second.
• The manifold will stay in join mode for 30 seconds allowing time to set the
controller into join mode.
Set the controller into join mode.
• Press UP and DN buttons together to enter Settings Mode.
• Press the M1 button when the display flashes “JOIn”.
• Use the up and down buttons to select which manifold to join with.
• JOIn r = Join with the manifold controlling the rear axle springs.
• JOIn F = Join with the manifold controlling the front axle springs.
• Press the M1 button to join the controller to the selected manifold.
• The display will show DONE when the joining process is complete.
• The M2 button will exit back to the settings mode.
• Press M2 button again to exit out of Settings Mode.
• Disconnect yellow wire from ground.
• Reinsert the yellow wire terminal into the molded cap
