ENGINE CONTROL
ENGINE WITH AN ELECTRONIC GOVERNOR
• The engine with an electronic governor has no control lever on the
injection pump.
• For controlling the engine with an electronic governor from body
side, the external engine control lever unit is needed separately. For
some applications, an engine control lever unit is included as stan
-
dard or installed to the vehicle with shipment.
• An engine control lever is available as an option.
• Firstly, install the external engine control lever unit to the body. Con-
nect its harness connector to the connector of the chassis harness
on the inner left side of the cab mounting bracket.
• If necessary, use an extension harness between the connectors of
the chassis harness and the external engine control lever unit so that
the control lever can be installed to any desired position.
• The characteristics of the governor can be switched by connecting or
disconnecting the two harness connectors (called junction A and
junction B respectively, which are located in the lower inner section
of the instrument panel in front of the front passenger seat.
• See the figure next for the positions of the junctions.
