Enhanced Easy-Stop Installation Diagrams
With Enhanced Easy-Stop, Standard 2S/2M and Premium 2S/2M, 4S/2M, and 4S/3M
sensor location designations will change depending on how the ECU/dual modulator
valve assembly is mounted. It may be mounted facing either the front or
the rear of the trailer. It is important that you identify the location of
these sensors before beginning any diagnostics. Sensor locations for both
front and rear-facing installations are depicted in Figures 4.1-4.10.
Note: Sensor locations for the 2S/1M Basic will not change.
