Sensor Orientation Test
The sensor orientation test must be performed as part of the end of line testing procedure.
Sensor Orientation Test Screen
Before beginning this test, look at the control port to see if it faces the front or rear of the trailer.
TOOLBOX PLUS™ will ask for this information to start the test (Step 5). To perform the sensor orientation
test:
1.
Raise the sensed wheel ends off the ground.
2.
Apply air to the emergency (supply) line to fill the air tanks and release the spring brakes so that the
wheels can be rotated.
3. Apply 12 volts DC to the ABS.
4. At the Trailer Main Menu, click on Component Test, then select Sensor Orientation Test to display the
Sensor Orientation Test screen.
When the Sensor Orientation Test screen first appears, the Control Port Facing field will display the
default —Front. This will occur regardless of the actual sensor orientation of the installation being
tested.
