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.
