EUTRAL
The Cummins- Quantum Engine requires different throttle com-
mand signals in Neutral than when In-Gear. These engines require a
voltage throttle signal of 0.9 VDC when unloaded at Neutral. When
a load is placed upon the engine by engaging the clutch, the throttle
command signal increases to 1.2 VDC.
The Throttle in Neutral Function allows the installer the ability to
adjust the throttle signal level at Neutral/Idle and also adjust a second
throttle signal level for when the clutch is engaged. The Neutral
value may be adjusted anywhere between 1 to 20% of the maximum
throttle output capability of the voltage circuit.
For example ; if the circuit has the ability to drive 0 to 5.00 VDC and
the value entered is 10, the output at Neutral would be 0.50 VDC.
The values of this Function are 01.0% to 50.0%. Throttle defaults are
based on the Throttle Profile selected.
A)Disconnect the Throttle Wire Harness from the CruiseCom-
mand Processor.
B) Connect the 8-Pin connector of the Service Field Test Unit to
the Processor Throttle connector and to the Throttle Wire Har-
ness. Refer to Figure 49:
C) Turn ON power to the Engine’s ECM. Ensure Power is On to
the Processor.
D)Depress either the Up or Down Arrow to activate the Function
Menu.
NOTE: This Function is used ONLY when the E0 Select Engine Throttle Profile is set for 03 - Cum-
mins Quantum.
