Troubleshooting Test Steps Values Results
11. Use the Electronic Service Tool to Reset the IVS Threshold
Limits
The electronic service tool can be used to change the “Idle Valida-
tion Min OFF Threshold” and the “Idle Validation Max ON Thresh-
old” in order to suit the type of throttle that is installed. The limits
are shown in the “Throttle Configuration” screen which is located
in the “Service” menu.
A. Refer to Test Step 8 and record the raw value of the throttle sig-
nal when the idle validation switch changes from the CLOSED po-
sition to the OPEN position.
Note: The default value for the “Idle Validation Min OFF Thresh-
old” is 21%. The lowest value that should be set is 5%. The de-
fault value for the “Idle Validation Max ON Threshold” is 25%.
The maximum value that is expected is 28%.
B. Set the “Idle Validation Min OFF Threshold” to 3% below the
raw value that was previously recorded.
C. Set the “Idle Validation Max ON Threshold” to 3% above the
raw value.
D. Enter the new threshold limits into the electronic service tool.
Click “Submit” on the electronic service tool screen.
E. Turn the keyswitch to the OFF position and wait at least 5 sec-
onds. Turn the keyswitch to the ON position.
F. Repeat Test Step 8. Check that the IVS operates within the
newly set threshold limits.
Result: The fault is cleared after programming
the new calculated values.
Return the engine to service.
Result: The fault is not cleared.
