Allison WTEC II Fault Code: 63 PID: SPN: 26 FMI: Kickdown input failed on
Subcode 26 is set when this function (Kickdown) is selected by calibration, the calibration designated input is active but not failed, and throttle position is less than the calibration value defined. The kickdown shift schedule is inhibited when subcode 26 is active. The service indicator will be turned on if it is selected by the calibration. The kickdown shift schedule is not inhibited, the code is cleared and the service indicator will be turned off if the kickdown input remains inactive for the calibration time period while throttle position is less than the calibration value.
