Programmable Monitori ng System
(PMS)
Th
e Programmable Monitoring System determines
the level of action that is taken by the Engine Control
Module (ECM) (10).In response to a condition that
ca
n damage the engine. These conditions are
identified by the ECM from the signals that are
produced from the following sensors.
