Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened compo-
nent life.
The replacement ECM must have the same serial number suffix or damage to the engine may result.
N OT E
If mission dictates, you may need to remove an ECM from an engine that is not in service. Refer to the fol-
lowing procedures to ensure that the configuration parameters match those in the faulty ECM. Be sure to
clear any logged codes if you use a substitute ECM.
