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.

If mission dictates, you may need to remove an ECM from an engine that is not in service. Refer to the fol-
lowing procedure to ensure the configuration parameters match those in the faulty ECM. Be sure to clear
any logged codes if you use a substitute ECM.
