Testing Sensor Sequence
Use this test to ensure the wheel sensors are functioning properly and at-
tached to the correct wheels. For example, if you spin the right front wheel,
Brake-Link™ displays the right front wheel speed. If it doesn’t, the sensor may
be malfunctioning. If it shows a wheel speed for a different wheel, the sensor
is connected to the wrong wheel.
Note:
This test supports EC-17, EC-30 and EC-30T.
To test Wheel Sequence:
1 Connect Brake-Link™ to the tractor or trailer and power-up (see “Con-
necting Brake-Link™ Components”, on page 20).
