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.
