Fuel System/Engine Management
Function Tests
The system allows the diagnostic tool to perform a
series of function tests on various actuators in the
engine management system. In some cases it is
necessary to make a visual observation of a
component and in other, if faults are present, DTCs
will be logged.
The function tests available are:
Function Examined Report Method
Instrument panel Visual inspection of
instruments
Idle speed control Stored fault code'
stepper motor
Purge control valve
Stored fault code'
Fuel pump relay Stored fault code'
Fuel pump operation Stored fault code'/Fuel
pressure test
Cooling fan Stored fault code'/fan
operation
2nd throttle controi Stored fault code'
stepper motor
• If a fault
IS
detected.
Checks/Adjustments
Adjustments
Using the Triumph diagnostic tool, it is possible to
reset the ECU to the factory default settings and to
balance the throttle bodies.
Further facilities are provided to allow correct
replacemenVadjustment of the primary throttle
position sensor and the primary throttle stepper
motor. These facilities are needed as, after
replacement of the parts concerned, adjustments
have to be made to specific voltage settings, all with
the throttles in a specific position.
Full details of these procedures are prOVided later in
this section.
Adaption status
Because the fuel system is adaptive, the tool is able to
automatically adjust to new working conditions. This
screen displays information as to the adaption status
of the vehicle which will show if it has adapted or not.
