GLOSSARY
Analog:
A signal which has a continuous range of
possible voltages.
Active:
The high voltage (+12V / +24V) state of a
digital input. Dependant upon vehicle system voltage.
Actual Gear: The actual physical gear of the
transmission, regardless of shift lever position or
controller operation.
Bus:
Serial communications link which interconnects
intelligent electronic modules.
Come-Home: A hardware function which allows
limited vehicle motion in the event of failure of certain
components.
Commanded Gear: The gear selected by the
combination of the shift lever position and the state of
the Forward, Reverse, Neutral, and Not Neutral inputs.
The ‘destination’ gear.
Current Gear:
The gear the controller is currently
attempting to drive the transmission into by the
application of commands to the valves.
Digital:
A signal which consists of only two voltage
levels - usually 0 volts and +5 volts. On/Off type
signals are also considered to be digital.
Downshift Inhibit: The prohibiting of downshifting, by
the ECU, to prevent harsh and abrupt shifts or
possible over speed conditions of the engine. The
downshift will be inhibited until the current speed ratio
will permit the shift to take place.
Fault:
An abnormal condition which results in a
perceived performance change or in a loss of function
which may result in performance loss or system
damage.
lntershift Pause Time:
The minimum time delay
between shifts. A value preprogrammed into the ECU.
Neutral Recoverable: The process where a detected
fault is maintained and displayed by the ECU until the
shift lever is cycled to neutral and the ECU detects the
proper combination of inputs for a legal neutral
condition, at which time the displayed fault will be
cleared. The fault code will still be maintained in ECU
memory for future recall.
Next Gear: The next gear the controller plans to enter.
The next gear will become the current gear if no faults
are detected and all conditions for entering the next
gear are met.
Nonvolatile Memory:
Memory that retains its data
even though power to the system has been removed.
Passive: The low voltage (0V) state of a digital input.
Previous Direction: The direction of vehicle motion
before a shuttle shift is initiated.
Previous Gear:
The previous current gear.
Sequence Shift:
The type of shift which consists of
shifting from a gear to an adjacent gear.
Sequential Shifting: Multiple sequence shifts with no
delay between shifts other than the programmed
intershift pause time.
Shuttle Shift:
A shift to a gear in the opposite
direction of vehicle travel made by moving the shift
lever between the Forward and Reverse positions
without hesitation in the Neutral position long enough
for the controller to obtain a legal neutral condition.
