Mounting the Compressor
• All of our compressors are sealed for moisture and dust resistance so
they can be mounted anywhere on the vehicle, though it is best to
mount it in a place out of direct contact with rain and snow. It is OK to
mount it underneath the vehicle, but keep it inside the frame rails away
from water and debris thrown o the tire.
• This is a dry compressor; therefore it is maintenance-free and can be
mounted in any position.
• It is best if mounted to something solid to reduce vibration and
noise. If mounting it to sheet metal or the bed of a truck, use
sound-deadening
material between the
compressor and the
mounting surface.
• Use the rubber
grommets supplied
on the feet of the
compressor to reduce
vibration.
• Attach the grey wire
from the main power
harness to the black
wire on the primary
compressor. The red
wire connects to +12V.
• Thomas Compressors
(black) will require a 20 amp fuse (each).
Mounting the Air Tank
• The air tank can be mounted anywhere on the vehicle in any position,
so long as the sensor is not pointed down. Having the sensor
mounted with the threads pointing up can cause damage to the
sensor.
• There is an 1/8”port in the tank that will accept the tank pressure
sensor.
Mounting the RidePro Air Valves
• The valves, like the compressor, are sealed and can be mounted in the
same locations. Although, if the vehicle will be exposed to freezing
temperatures, it is a
good idea to mount
them in the engine
bay if possible to
reduce the possibility
of freezing.
• They can be mounted
in any position.
• Attach the ground
strap to a good, clean
ground (preferably the
frame).
• The exhaust port will
be left open.
• The valve is held closed with the pressure in the tank. If tank pressure
drops below air spring pressure they will equalize, deating all 4 air
springs.
Use spacer for
better cooling

Routing the Airline and Fittings
• Make all airline cuts with a razor or
tubing cutter
(part # - 90001081) .
The cut must be clean and straight
or it will not seal.
• All ttings are DOT approved
push-to-connect style. They
are very simple to use and are
reusable. Firmly push the airline
into the tting to attach. To
release the airline push the collar
on the tting back towards the
tting and pull the airline out.
• Use thread sealant on all ttings. The white compound that is on the
ttings is an anti-gauling compound.
• Do not over-tighten the ttings. This could result in breaking the tting or
damaging the air spring.
• All of our airlines are DOT approved so they are very strong, but keep them
away from any sharp edges. Also, when passing through a hole in the
frame use a grommet.
• Keep away from intense heat, including muers and exhaust manifolds.
• Use zip ties or other fasteners to secure the airline.
use thread
sealant to
avoid leaks
Use Tubing Cutter
(part # 90001081)
for straight ends.

Mounting the Air Pressure Sensors
• These sensors are voltage based and do not need to be grounded.
• Use thread sealant when installing pressure sensors in valve block.
• Sensors can not be pointed down
( debris can collect and cause false readings)
• The ECU is water proof and may be mounted in the engine bay or under the
vehicle.
• The ECU is a wireless device, do not mount it fully enclosed by metal. Doing
so will reduce the wireless range.
• The Display is NOT water proof and needs to be mounted inside the vehicle.
It should be mounted in a location where it can be accessed with ease.
• The Display has a nameplate on the back of the display that can be used
with a magnetic dash mount.
• The orientation of the display can be changed to help tailor it to your install.
• Refer to Page 21 for a complete wiring diagram.

Ride Height Sensors
If the electrical range of travel
is exceeded, the system may
function erratically or not at all.
Also note that if the sensor
has very little travel, the
system may not perform to its
potential.
It may be necessary to shorten
the sensor arm to increase
travel.
• The Height Sensor Option uses 4 height sensors (one at each wheel). They are weather proof and may be mounted in any position as well as
“clocked” in any position. (There is not a dierence between the left and right sensors.) These sensors are typically mounted to the chassis /
frame rail.
• A linkage with rubber ends connects the sensor arm and a suspension component. On
most front suspensions, the linkage will attach to the upper or lower control arm. On most
rear suspensions, it will attach to the axle or control arm.
• The main goal when mounting the sensor is to achieve as much sensor rotation as
possible without exceeding the sensors limits.
• Although the sensor arm will rotate 180 degrees, it must remain in the middle 90 degrees
throughout suspension travel. See diagram below for sensor travel limits.
• It may be necessary to shorten the sensor arm and drill a new hole to ensure the arm is
rotating enough during suspension travel to accurately determine vehicle height.
• The sensor arm can also be removed from the sensor and clocked in four dierent
positions. It may also be necessary to bend the sensor arm and/or linkage to achieve
proper clearance and alignment.
• The sensor will be mounted to the frame using ¼”self tapping screws or bolts. A special
shouldered bolt is supplied to attach the rubber rod ends to the suspension and the
sensor arm; this will avoid over tightening.
• Make sure the sensor has adequate clearance from all suspension components throughout
suspension travel. Check tire clearance, lock to lock and throughout suspension travel.
External Ride Height Sensor Installation
Connecting Sensor Harnesses to ECU
Run the harness from the sensors to the Main
Harness (AirPod). We recommend marking the
harnesses at the end that will plug in at the
Main Harness (AirPod). The 4 plugs in the Main
Harness are labelled for each corner. Plug the
correct harness into each plug.
AIRPOD ONLY! The AirPod has 4 clips on the
main board to secure the plugs for the level
sensor harnesses. The female plug on the sensor
harness will attach to these clips. The plug slides
onto the clip from the release side of the clip.
AIRPOD ONLY! Start the plug on the retainer
and slid it until it clicks. This will lock the harness
in place.

1- The linkage rod can be cut to length
using side cuts.
2- The linkage rod can be bent by hand.
This can come in useful when trying
to get clearance on an obstacle.
3- After getting the linkage cut to length
and shaped, line up the end with the
end link.
4- Push the end of the linkage into the
end link. The linkage doesn’t require
anything to hold it into the end link.
5
- Once both sides of the linkage have
been nished, secure the linkage to
the sensor and suspension.

MOUNT THE MAIN UNIT:
1- Mount the base at to the vehicle surface (do not bend the base)
2- Secure the base with self-tapping screws or bolts.
3 - If optional cover is used, secure the cover to the airpod base using the supplied screws.
CONNECT AIR LINES:
1 - Airline cuts must be straight and clean - use a razor blade or tubing
cutter. (part # - 90001081)
2 - All ttings are DOT-approved, reusable, push-to-connect style. Firmly
push the airline into the tting to attach. To release the airline, push
the collar on the tting back towards the tting and pull the airline
out.
3 - All of our airlines are DOT-approved so they are very strong. Secure
the airline with zip ties, keep them away from any sharp edges, and
when passing through a hole in the frame, use a grommet.
4 - Keep away from intense heat including muers and exhaust
manifolds.
CONNECT POWER HARNESS:
1 - Connect the red power wire directly to the
battery.
Use included fuse within 18” of battery.
3 Gallon - 30 amp fuse
5 Gallon - 40 amp fuse
2 - Connect the yellow ignition wire to switched
12v.
(Fuse Panel is the best location)
3 - Connect the black wire to chassis ground.

PRESSURE AND HEIGHT CALIBRATION (with Level Sensors)
Calibration:
!ATTENTION!!!!! The vehicle MUST be running in order to calibrate this system!
Only turning the key on will NOT work!
Hooking it to a battery charger will NOT work!
The vehicle must be running!
During the Calibration sequence, the RidePRO e5 records information specic to the vehicle in which it is installed (inate and deate speed, if
level sensors are present, how long the compressors take to ll the storage tank, etc.) The RidePRO e5 then uses this information to attain the
proper preset heights in the fewest possible steps, using the most intelligent method. For example, after calibration the RidePro knows that the
front of the vehicle is heavier and therefore slower than the rear, so it will inate the front rst then allow the rear to catch up just as the vehicle is
achieving ride height.
NOTE: The RidePRO e5 system is a very intelligent system. Attempting to calibrate this system on a non-running vehicle will cause errors.
Trying to hook the system up for a“TEST RUN”? When the system is powered up, it will work manually using the inate and deate buttons only.
The preset buttons will not work until calibration is complete. Calibration should not be run until vehicle is running and driving.
NOTE:
Target on pressure based systems is + or - 7 PSI
Target on height based systems is + or - 1/4”
DO NOT RERUN CALIBRATION ON A SYSTEMTHAT HAS BEEN PREVIOUSLY CALIBRATED. IF YOU ARE HAVING A

Troubleshooting Guide
RidePRO e5 will not turn on.
Diagnosis : No LED light on top of ECU
Solution : Check RED wire for constant 12 volts, YELLOW wire for 12 volts with key ON, and the 2 fuses in ground wires from
ECU. Also, verify that you have a good ground on the 2 ground wires.
Compressor will not turn on.
Diagnosis A: Check Setup Menu to ensure compressor(s) is turned on.
Solution A: Select the box to make sure it turns red with a check mark.
Diagnosis B: 12 volts not present at Red wire on compressor.
Solution B: Check fuse and connections. (20 amp fuse on Thomas compressor)
Diagnosis C: 12 volts present at Red wire on compressor but still doesn’t run.
Solution C: Check connections between Black wire on compressor and Blue/Gray wire on ECU. Also check FUSES in
Black wire from ECU to Ground.
Diagnosis D: 12 volts present at Red wire on compressor but still doesn’t run.
Solution D: The compressor has gotten hot and thermals out. The air compressors have a thermal safety built in. If the
compressor gets too hot, it will shut itself o. Let the compressor cool, it should come back on.
Compressor will not turn o.
Diagnosis A: Tank pressure reads 0 psi all the time or stays at the same pressure regardless of actual tank pressure.
Solution A: 1. Check harness and plugs.
2. Replace pressure sensor.
Diagnosis B: Tank pressure builds normally but will not reach 150psi.
Solution B: Replace compressor.
One air spring leaks down over a period of time.
Diagnosis A: Leak between delivery port on valve block and air spring. ALL FITTINGS NEED SOME KIND OF THREAD SEALER.
Solution A: Air springs almost never leak. Spray all ttings with soapy water. Tighten tting and/or remove and
replace thread sealant. Cut 1” o of end of airline and reinsert.
Diagnosis B: Exhaust valves leaking. Air seeps past exhaust valve and out exhaust port.
Solution B: Usually caused by debris stuck on valve seat. Inate and deate several times or disassemble valve. Information
about servicing the valves can be found at: https://www.ridetech.com/tech/solenoid-valve-service/
One air spring leaks up over a period of time.
Diagnosis A: Inate valves leaking. Air seeps past inate valve and into air spring.
Solution A: Usually caused by debris stuck on valve seat. Inate and deate several times or disassemble valve. Information
about servicing the valves can be found at: https://www.ridetech.com/tech/solenoid-valve-service/
The 2 front or all 4 air springs leak down over a period of time.
Diagnosis A: Check tank pressure. There is a leak in the supply side of the system. This could be at the compressor, tank, or supply
ports on the valve. The valves are held closed by the tank pressure. If the tank pressure gets below the air spring pressure, the
air spring will leak down with the tank. An easy way to check this; make sure the compressor runs until it shuts o. Write down the
tank pressure and let the vehicle sit over night. If the compressor kicks on right away the next time you turn on the system, you
have a leak on the supply side of the system.
Solution A: Spray all ttings with soapy water. Tighten tting and/or remove and replace thread sealant. Cut 1” o
of end of airline and reinsert.
Control panel switches activate the correct air spring, but the air pressures read the wrong air spring.
Diagnosis : Ex: Inating the RF air spring changes the top left psi readout on the panel
Solution : Swap pressure sensor harnesses at the sensors.
Pressure readings are not moving, always reads 168 psi or 0 psi.
Diagnosis : ECU is not receiving a proper signal from the sensor.
Testing : Switch the wires between two sensors, if the corner you switched it with now reads zero, you have a bad sensor.
Solution : 1. Check pressure sensor harness connections.
2. Replace sensor.
Height sensor bars read the incorrect corner.
Diagnosis : Ex: When inating RF air spring LF bar increases
Solution: Swap height sensor harnesses at ECU.

Troubleshooting Guide
Control panel switches do not activate the correct air spring.
Diagnosis : Ex: LF switch actuates the RF air spring.
Solution : Swap airline at the valve block.
Presets work, but does not achieve target.
Diagnosis A: Air tank is too small. Air spring pressure equalizes with tank pressure before achieving preset pressure/height.
Solution A: Reprogram #1 preset for the highest psi that allows the suspension to bottom out. You do NOT need to
let all of the air pressure out of the air springs. Let the air out of each end of the vehicle until it stops moving. This
should be your #1 setting. You will likely have air pressure left in the air springs. This will give it a“head start”. If this
does not x the issue, you need a larger air tank. A larger vehicle should always have a 5 gallon air tank.
Diagnosis B: Tank pressure leaks down.
Solution B: Fix leak on supply side of system.
Diagnosis C: Pressure sensors and/or airline are not attached to corresponding air spring.
(Ex: RF button must activate RF air spring and top right number on display.)
Solution C: Swap airline at delivery port on valve and/or air pressure sensor harness.
Diagnosis D: Mechanical height sensors are out of range. Under “System Setup”check the presets voltages. If one or more are at
4.5v or .5v then the sensor is traveling beyond its range of travel.
Solution D: Reduce or change travel of sensor by either changing linkage length, changing sensor arm length or by
rotating sensor.
Low voltage error.
Low Voltage Error is triggered if the system sees under 10.5 volts for an extended period of time. It will turn the compressors o to prevent
the battery from being drained. The compressors will come back on after the battery voltage increases and stabilizes.
Solution A: Make sure the vehicle is running.
Solution B: Check all of your connections at the grounds and battery.
Solution C: If it is a common occurrence, you may need a larger alternator.
One corner will not inate or deate, but the others inate and deate.
Diagnosis A: With the vehicle running, check to see if the valve clicks when the button is pushed.
Solution A: If no click, check the harness going to valves and the grounds at the valve block.
Diagnosis B: With the vehicle running, check to see if the valve clicks when the button is pushed.
Solution B: If no click, check the grounds at the valve block. You can also test the wire of the coil of the solenoid that isn’t
working. Each coil of the valve block has 2 wires. One wire is ground, the other wire is the control wire. You should see 12
volts on this wire when the button for the solenoid is pushed. Use a volt meter on this wire to see if you have 12 volts when
the button is pushed.
Diagnosis C: With the vehicle running, check to see if the valve clicks when the button is pushed.
Solution C: If valve clicks, but does not open. The plunger in the valve can be badly dimpled and needs replaced. If the
plunger is badly dimpled, it can get stuck in the hole in the valve, not allowing it to open. Information about servicing the
valves can be found at: https://www.ridetech.com/tech/solenoid-valve-service/
Diagnosis D: System is getting LOW voltage.
Solution D: Start the vehicle and test to see if you are getting at least 12.5 volts at the battery. A battery charger isn’t
enough to run the system.
All pressure readings 0 psi.
Diagnosis : 5 volt is shorted to ground.
Testing : Verify that the pressure sensors are plugged into the harness and there is pressure in the system.
Solution : 1. Check the pressure and level sensor harness to see if there is a short to ground or the harness has an
internal short. This could be at a spot where the harness passes through metal or if the harness has been pinched.
Vehicle not obtaining correct height when going to a preset.
Diagnosis : Vehicle is not at the height you initially programmed.
Solution: This is a learning system, the more you use it, the more accurate it will get.

Tips & Tricks
DO NOT RERUN CALIBRATION ON A SYSTEMTHAT HAS BEEN PREVIOUSLY CALIBRATED. IF YOU ARE HAVING A
PROBLEM WITH THE SYSTEM, TRYING TO RECALIBRATE WILL MAKE IT DIFFICULT TO DIAGNOSE THE PROBLEM.
When inating and deating the vehicle manually, push both buttons for one end of the vehicle at the same time.
Explanation: When you do one corner at a time, it is harder to get the vehicle level at the height you are trying to achieve. By
pushing both inate buttons at the same time, each side of the vehicle works together to lift the vehicle. When you get close to
the height you are trying to obtain, then you can adjust the air in each corner individually.
Pressure dierential from side to side.
Explanation: It is not uncommon for a vehicle to have more pressure in one side. Several things can aect the air pressure
from side to side; weight distribution and chassis twist are the two most common causes. Airing up both front or both rear at the
same time will help get the vehicle closer to level than trying to do it one corner at a time. A 10-15 psi dierential from one side
to the other is not uncommon.
Tip: After you have leveled the vehicle, take a look at all 4 pressures. If two corners opposite of each other are your higher
pressures, you may be cross loading the vehicle. Example: The Left Front has a higher pressure than Right Front and Right
Rear has a higher pressure the Left Rear, there’s a good chance the 2 higher pressure air springs are pushing against each other.
Try getting the pressures closer to the opposite side of the vehicle on each end and see how the vehicle sits.
Swapping airlines to help diagnose a problem.
Explanation: Air lines can be swapped from one port to another to help diagnose a problem. This can help you narrow down
where a problem may be.
Example: Right rear will not air up, but left rear will - switch the right rear and left rear air lines. The operation of the rear will
now be switched at the control panel, but the air pressures will still be correct for the corners. If the right rear will still not air
up using the left rear button, your problem is somewhere from the right rear valve to air spring. If the right rear will now air
up using the left rear button, the problem is in the wiring controlling the valve.
Swapping pressure sensors harness plugs to help diagnose a problem.
Explanation: Pressure harnesses and sending units can be swapped from one port to the another to help diagnose a problem.
Example: Right rear pressure reading zero, but other corners reading correctly - switch the right rear pressure sensor harness
with the left rear. Keep in mind, the rear pressures will now read backwards of each other. If the zero reading moves to the
left rear, the sensor is bad or there is a problem in the wiring. If you move the sensor wires and now the left rear has a reading,
there is probably no air in the right rear corner. Check your valve, air line, and air spring for the right rear.
Tip: You can also switch pressure sensors around to help determine if you have a bad sensor. Make sure you deate the
corners you are swapping to eliminate the pressure at the sensor. If you are removing the tank sensor, dump the tank
before removing it. This can be done in the Menu.
Using the“Diagnostics” tab to help verify correct operation of the system.
Explanation: If you go to the “Diagnostics” tab under the “Menu”, you can see all 4 corner pressure readings. If you have level
sensors on your vehicle, you will also see level sensor voltage readouts. Battery voltage is also displayed on this screen.
Tip: If you operate one corner at a time, you can verify the correct corner of the vehicle is moving. The corner pressures (and
level sensor voltages if equipped) should also be moving on the corner you are operating.
SUSPENSION BIND
Ever noticed that when you lower any vehicle o of a lift or jack stands that it is sitting several inches higher than normal? This
condition is due to Suspension Bind, and all vehicles have it. Three dynamics lead to suspension bind:
TECH TIP
1. Tire Scrub - The arc created by the control arm swing will try to push your tires apart or pull them together, (basically
changing the track width). However, friction between the tire and ground does not allow the tires to slide, reducing vehicle
movement. This can be especially dramatic with sticky tires and concrete.
2. Control Arm Bushing – Friction between the bushing and the frame brackets will also reduce vehicle movement. This is why
control arm bolts must be tightened at ride height. Over-tightening the bolts can lead to very excessive suspension bind.
3. Shock Absorbers – The shock absorber’s job is to reduce suspension movement. The stier the shock absorber, the more
suspension bind.
With an air suspension vehicle, it is always best to over inate the air spring and then deate back down to the target pressure
to alleviate some suspension bind.
