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)PWM 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 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 J1:45 for Idle Validation Switch 1 (IVS1) and J1:44 for Idle Validation Switch 2 (IVS2).
Table 2
Values    Default    
No
Yes     Yes    Idle Validation Minimum Off (Open) Threshold
This 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 3 and Table 4.
Table 3
Throttle Position Sensor (TPS)     Idle Validation Switch (IVS)     Throttle Demand Output     Fault Status     Comment    
TPS< IVS Min OFF     OFF     Minimum Position     Raise missing idle     Force throttle demand to minimum    
TPS< IVS Min OFF     ON     Throttle Position     Clear missing idle     Normal operation    
Table 4
Range    Default    
0 to 100%     21%    Idle Validation Maximum On (Closed) Threshold
This 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 5 and Table 6.
Table 5
Throttle Position Sensor (TPS)     Idle Validation Switch (IVS)     Throttle Demand Output     Fault Status     Comment    
TPS> IVS Max ON     OFF     Throttle Position     Clear unexpected idle     Normal operation    
TPS< IVS Min Off     ON     Minimum Position     Raise unexpected idle.     Force throttle demand to minimum    
Table 6
Range    Default    
0 to 100%     25%    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 7
Range    Default    
0 to 100%     5%    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.
