(10) Upper Diagnostic Limit (Default=90)
PWM throttles and communications port throttles
do not require any additional programming. If
a multi-position switch is selected, additional
parameters must be programmed. Refer to the
Troubleshooting Guide, "Multiposition Switch Setup".
If an analog throttle is selected, the following
parameters must be programmed into the ECM.
Idle Validation
All analog throttles on mobile applications require an
idle validation switch. If this parameter is programmed
to "Yes", the ECM will look for this switch input on pin
J1:P45 for Idle Validation Switch 1 (IVS1) and J1:P44
for Idle Validation Switch 2 (IVS2).

Idle Validation Minimum Off
Threshold
This is the minimum throttle percentage that will be
detected by the ECM when the idle validation switch
is OFF. If the ECM detects a throttle percentage
below this value with the idle validation switch in the
ON position, a fault code will be generated.
Table 17
Range
0 to 100 percent
Idle Validation Maximum On
Threshold
This is the maximum throttle percentage that will be
detected by the ECM when the idle validation switch
is OFF. When the idle validation switch in the OFF
position and the ECM detects a signal that is higher
than the programmed value, the ECM will generate a
fault code and the engine will remain at idle.
Table 18
Range
0 to 100 percent
Lower Diagnostic Limit
This is the minimum throttle percentage that should
be detected by the ECM in normal operation when
the pedal is in the "off" position. A value below this
limit will generate a short circuit diagnostic code.
The range of this diagnostic detection area is from
0 percent to the programmed value for the lower
position limit.
Table 19
Range
0 to 100 percent
Upper Diagnostic Limit
This is the minimum throttle percentage that is
detected by the ECM in normal operation when the
pedal is in the maximum position. A value above this
limit will generate an open circuit diagnostic code.
The range of this diagnostic detection area is from
the programmed value of the upper position limit to
100 percent.
