SCAN TOOL DATA DEFINITIONS
1-2 Shift Error
This parameter is the difference between the desired 1-2 shift time and the actual 1-2 shift time. A
positive number indicates a firm or fast shift, the actual shift time was shorter than the desired shift time.
A negative number indicates a soft or slow shift, the actual shift time was longer than the desired shift
time. This value is only accurate if the shift was adaptable.
1-2 Shift Time
This parameter is the actual time of the last 1-2 shift. The shift time is based on the engine RPM drop
after the commanded 1-2 shift. This value is only accurate if the shift was adaptable.
1-2 Sol.
Displays ON or OFF. This parameter is the commanded state of the 1-2 shift solenoid valve. ON
represents a commanded energized state, current is flowing through the solenoid. OFF represents a non-

commanded state, current is not flowing through the solenoid.
1-2 Sol. Open/Short to GND
Displays Yes or No. This parameter indicates if an open or short to ground exists in the 1-2 shift solenoid
valve feedback signal to the PCM. This parameter is valid only when the 1-2 shift solenoid is commanded
OFF.
1-2 Sol. Short to Volts
Displays Yes or No. This parameter indicates if a short to voltage exists in the 1-2 shift solenoid valve
feedback signal to the PCM. This parameter is valid only when the 1-2 shift solenoid is commanded ON.
1-2 Tap Cell (4-16)
Displays kPa or psi. This parameter displays the amount of pressure varied from a calibrated base line
pressure for shifts. Each TAP Cell is based on a calibrated shift torque value. Each TAP Cell value is
calculated from the last shift time. This cell pressure is used in addition to the calibrated base line
pressure to adjust the apply of a clutch or band during the next shift.
2-3 Shift Error
This parameter is the difference between the desired 2-3 shift time and the actual 2-3 shift time. A
positive number indicates a firm or fast shift, the actual shift time was shorter than the desired shift time.
A negative number indicates a soft or slow shift, the actual shift time was longer than the desired shift
time. This value is only accurate if the shift was adaptable.
2-3 Shift Time
This parameter is the actual time of the last 2-3 shift. The shift time is based on the engine RPM drop
after the commanded 2-3 shift. This value is only accurate if the shift was adaptable.
2-3 Sol.
Displays ON or OFF. This parameter is the commanded state of the 2-3 shift solenoid valve. ON
represents a commanded energized state, current is flowing through the solenoid. OFF represents a non-
commanded state, current is not flowing through the solenoid.
2-3 Sol. Open/Short to GND
Displays Yes or No. This parameter indicates if an open or short to ground exists in the 2-3 shift solenoid
valve feedback signal to the PCM. This parameter is valid only when the 2-3 shift solenoid is commanded
OFF.
2-3 Sol. Short to Volts
Displays Yes or No. This parameter indicates if a short to voltage exists in the 2-3 shift solenoid valve

feedback signal to the PCM. This parameter is valid only when the 2-3 shift solenoid is commanded ON.
2-3 Tap Cell (4-16)
See 1-2 Tap Cell (4-16)
3-2 Downshift Sol.
Displays On or Off. This parameter indicates if the 3-2 shift solenoid valve assembly is currently
commanded On or Off. The solenoid commanded state is based on the transmission temperature. The
solenoid will change states during a 3-2 downshift to regulate the appropriate pressure. The commanded
state of the solenoid occurs at approximately 30 mph with a throttle increase.
3-2 Downshift Sol. Open/Short to GND
Displays Yes or No. This parameter indicates if an open or short to ground exists in the 3-2 shift solenoid
valve assembly feedback signal to the PCM. This parameter is valid only when the 3-2 shift solenoid is
commanded OFF.
3-2 Downshift Sol. Short to Volts
Displays Yes or No. This parameter indicates if a short to voltage exists in the 3-2 shift solenoid valve
assembly feedback signal to the PCM. This parameter is valid only when the 3-2 shift solenoid is
commanded ON.
3-4 Shift Error
This parameter is the difference between the desired 3-4 shift time and the actual 3-4 shift time. A
positive number indicates a firm or fast shift, the actual shift time was shorter than the desired shift time.
A negative number indicates a soft or slow shift, the actual shift time was longer than the desired shift
time. This value is only accurate if the shift was adaptable.
3-4 Shift Time
This parameter is the actual time of the last 3-4 shift. The shift time is based on the engine RPM drop
after the commanded 3-4 shift. This value is only accurate if the shift was adaptable.
4WD
Displays Enabled or Disabled. This parameter indicates whether the vehicle is currently in a four-wheel
drive mode.
4WD Low
Displays Enabled or Disabled. This parameter is the signal state of the four-wheel drive low circuit.
Enabled indicates a 0 voltage signal, 4WD Low requested. Disabled indicates a B+ voltage signal, 4WD
Low not requested.
