Typical Range of Throttle
(1) Lower Diagnostic Limit (Default=5)
(2) Lower Position Limit (Default=10)
(3) Initial Lower Position (Default=20)
(4) Idle Validation Minimum Off Threshold (Default=21)
(5) Idle Validation Maximum On Threshold (Default=25)
(6) Lower Dead Zone % (Default=8)
(7) Upper Dead Zone % (Default=5)
(8) Initial Upper Position (Default=70)
(9) Upper Position Limit (Default=85)
(10) Upper Diagnostic Limit (Default=95) Analog throttles and digital throttles require 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 or a digital throttle is selected, the following parameters can be programmed into the ECM.Lower Diagnostic Limit
This parameter 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 1
Range Default
0 to 100% 5% Lower Position Limit
This parameter is the minimum throttle percentage that will be interpreted by the ECM as zero throttle. This parameter is used with the value of initial lower position limit to make an allowance for manufacturing tolerances between different pedals.
Table 2
Range Default
0 to 100% 10% Initial Lower Position Limit
This parameter is the maximum throttle percentage that will be interpreted by the ECM as zero throttle. This parameter is used with the value of the lower position limit to make an allowance for manufacturing tolerances between different pedals.
Table 3
Range Default
0 to 100% 20% Idle Validation
All analog throttles and digital throttles can have an idle validation switch. If this parameter is programmed to "Yes", the ECM will look for this switch input on pin J1:22 for Idle Validation Switch 1 (IVS1) and J1:40 for Idle Validation Switch 2 (IVS2).
Table 4
Values Default
No
Yes No Idle Validation Minimum Off (Open) Threshold
This parameter is the minimum throttle percentage that will be detected by the ECM when the IVS is ON (Closed).If the ECM detects a throttle percentage below this value with the idle validation switch OFF (Open), a fault code will be generated and the engine will remain at idle.Refer to Table 5 and Table 6.
Table 5
Throttle Position Sensor (TPS) Idle Validation Switch (IVS) Throttle Demand Output Fault Status Comment
TPS< IVS Min OFF OFF Minimum Position Raise IVS fault Force throttle demand to minimum
TPS< IVS Min OFF ON Throttle Position No fault Normal operation
Table 6
Range Default
0 to 100% 21% Idle Validation Maximum On (Closed) Threshold
This parameter is the maximum throttle percentage that will be detected by the ECM when the idle validation switch (IVS) is OFF (Open) . When the idle validation switch is OFF (Open) and the ECM detects a signal that is higher than the programmed value for IVS Max ON, the ECM will generate a fault code and the engine will remain at idle.Refer to Table 7 and Table 8.
Table 7
Throttle Position Sensor (TPS) Idle Validation Switch (IVS) Throttle Demand Output Fault Status Comment
TPS> IVS Max ON OFF Throttle Position No fault Normal operation
TPS< IVS Min Off ON Minimum Position Raise IVS fault Force throttle demand to minimum
