Manual Operation:

The 

LevelTow

 Compressor System also has a manual control function.  This function allows you to manually 

infl ated or defl ate the system.  To use the manual function you must fi rst turn the system off  by pushing the 

main power button.  Once the system is turned off  you can push the rocker switch up to infl ate or down to 

defl ate.  To put the system back in level mode push the main power switch to turn it back on. 

Note:

If the Activation Button is illuminated blue and the manual button is pushed the truck will relevel itself.  The 

activation button has to be off  for the manual control to be used and the truck remain at the height.

Troubleshooting:

If after installation you fi nd the system not functioning correctly, you may have the sensor operating the wrong 

direction.  You can verify this by turning the truck on and check that the activation button is illuminated blue. 

Unhook one end of the linkage and move the sensor arm by hand.  If when you move the arm down (Keep in 

mind there is an 20 second delay) and the Air spring infl ates, the sensor is operating in the wrong direction.  

You can fi x this problem without remounting the sensor by swapping the blue and green wires in the har-

ness at the sensor.  To do this, with the truck turned off ,  simply unplug the harness from the sensor.  Using 

a small screwdriver pop the purple retainer out of the plug by prying up on each end of it.  After removing the 

retainer if you look into the end of the plug you will see a tang holding each wire terminal.  Simply pry it down 

just enough to release the terminals of the blue and green wires.  Swap the blue and green wire postion and 

reinstall the wires into the plug paying attention to the direction of the small tab on the wire terminal.  This 

tab will point to the center of the plug.  Push the wire terminals into the plug making sure they catch on the 

tang and reinstall the purple retainer.  After plugging the sensor back in you can confi rm correct operation by 

turning the truck back on moving the sensor arm up, the Air spring should infl ate.  If the system is functioning 

correctly, shut the truck off  and reattach the linkage.
