The Air Lift Wireless AIR Compressor System # AL74000 will show an error whenever there is any type of issue with the system.

Generally this is an issue with the remote communicating with the system, a blockage, or a leak. I would inspect the compressor system and all of the air lines to make sure there are no issues. You can check for leaks using soap and water. If you find a leak disconnect the hose and make sure the tubing is cut as square as possible. If you find a block you'll likely need to replace that piece of tubing.

If you don't find anything wrong with the system try to join the controller with the manifold again:

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
