REGEN/ INHIBIT Switch Overview
Operation of the REGEN/ INHIBIT switch differs with respect to
engine manufacturer.
However, on single switch systems as shown, the REGEN side of the
rocker switch is engaged (the dwell to hold the switch differs by
manufacturer) to “FORCE” an emission system regeneration.
The center position of the switch allows the ECU to control
regeneration “Automatically”
When the INHIBIT side of the rock switch is engaged, regeneration
is “INHIBITED”
NOTE: Force Regeneration is available ONLY when allowed by the
engine ECU via display of appropriate symbology (see engine
manufacturer documentation for more information.)

Regeneration of the emissions system
is active and high exhaust temperatures
are potential. Engine performance MAY
be affected
The engine particulate filter is
potentially in need of regeneration.
Regeneration of the emissions
system is inhibited due to
activation of the inhibit switch
