Kohler Command Pro EFI ECH940 Owner's Manual

Electronic Fuel Injection (EFI) System

EFI is an electronically-controlled fuel

management system which is monitored by an

Electronic Control Unit (ECU). A Malfunction

Indicator Light (MIL) will illuminate if problems

or faults are detected. Servicing by a Kohler

authorized dealer is necessary.

Fuel System Components

High pressure components inside fuel pump

module are not serviceable. Engines are

equipped with a special EFI fuel ﬁ lter. See

Maintenance Schedule.

Fuse Replacement

These engines have three (3) blade type

automotive fuses. Engines equipped with a

high output charging system, will have one (1)

60-amp large blade type automotive fuse, in

addition to the three (3) blade type automotive

fuses. However, the 30-amp fuse is then non-

functional, as the 30-amp charging system

circuit has been disabled.

Replacement fuses must have same rating as

blown fuse. Use fuse chart below to determine

correct fuse.
