MERITOR WABCO ABS ENHANCED EASYSTOP™ CONVERSION KITS
Meritor WABCO has created a series of retrofit kits to replace the previous Easy-Stop platform, to
the current production Enhanced Easy-Stop platform.
Easy Stop was installed on production built trailers between
March 1997 and February 2001.
Enhanced Easy-Stop incorporated current technology to address regulatory PLC requirements and
has been installed from March 2001 to present.
To determine the proper kit , find the existing Easy-Stop ECU/Valve part number
that needs to be replaced.
Then determine if you will pull the diagnostics from the tractor (power adapter equipped kits)
or from the trailer (power adapter with diagnostic adapter equipped kits).
