Your trailer has two wheel speed 
sensors and  two ABS modulators 
that are plumbed for axle control.

The MC-30

 controller you have 

installed is currently confi gured  for 
4S/2M axle control.

Provide power to the MC-30

 controller 

and verify the current confi guration 
using the LEDs or blink codes.

Remove the magnet.

2S/2M Axle

Stop!  You do not need to perform an 
ABS control toggle in this case.
