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 diff 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 diff 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 (Air
P
od). We recommend marking the
harnesses at the end that will plug in at the
Main Harness (Air
P
od). The 4 plugs in the Main
Harness are labelled for each corner.
P
lug the
correct harness into each plug.
AIRPOD ONLY!
The Air
P
od 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.
