Figure 6.5 Air Inlet Temperature Installation Wiring
The sensor requires a M18 x 1.5 (metric) or ¾ -16 (Imperial) thread and
should be installed after the air cleaner with a tightening torque of 20+/-3Nm.
It should be noted that the sensor is supplied without an O-ring. An O-ring
must be used and the material should be selected to suit the application
environment.
6.3 Engine Electrical Fuel Lift Pump
6.3.1 Engine Electrical Fuel Lift Pump Operation
The fuel lift pump is a mandatory installation component which can be
supplied on engine or loose for on machine mounting. The fuel pump is used
to ensure a continuous fuel flow is provided to the engine fuel pump. The
pump is available in 12 and 24V options.
The electric lift pump is energized whenever the ignition key switch supply to
pin 69 of the J1 ECM connector is activated. This enables the pump to be
used as an electric fuel priming pump when required (120seconds is the
maximum time allowed for fuel system priming using the electric lift pump). It
should be noted that after ignition key ‘ON’ the pump will run for a maximum
of 120seconds without seeing the engine speed increase from 0rpm. If the
engine speed does not exceed 0rpm within 120seconds then the lift pump will
turn off. The lift pump will then re-start as soon as the engine ECM sees the
actual engine speed exceed 0rpm.
6.3.2 Engine Electrical Fuel Lift Pump Configuration
There is no service tool configuration required to enable the fuel lift pump
feature. The service tool does however provide a means of overriding the
engine ECM control of the pump relay to aid system diagnostics. This
override parameter can be found in the following service tool menu location:
Diagnostics / Diagnostic Tests / Override parameters
It should be noted that the service tool override will be disabled when:
• The override will not operate if the engine speed is greater than 0rpm
• The test will abort if the engine speed exceeds 0rpm
6.3.3 Engine Electrical Fuel Lift Pump Installation
6.3.3.1 1204F Electric Lift Pump Installation
The fuel lift pump requires a fused battery positive and battery negative
connection. The control of the lift pump is provided by the engine ECM via the
ECM J1 connector and a fuel pump supply control relay which requires
machine mounting by the customer.
