For 1990-2009 cars only
CPP Switch: This parameter displays the state of the clutch
pedal switch circuit input. The scan tool will display APPLIED when the clutch pedal
is depressed, and RELEASED when the clutch pedal is released.
Reverse Inhibit Solenoid Command: This parameter displays the commanded state of the reverse inhibit solenoid. When the vehicle speed is greater than 5 km/h (3 mph), the solenoid is commanded ON, inhibiting shifts to Reverse. When the vehicle speed is less than 5 km/h (3 mph), the solenoid is commanded OFF, allowing shifts to Reverse. The scan tool will display ON/OFF.
Skip Shift Lamp Command: This parameter displays the commanded state of the skip shift lamp. The scan tool will display ON/OFF.
Skip Shift Solenoid Command: This parameter displays the commanded state of the skip shift solenoid. The scan tool will display SKIP/NO SKIP.
TFT Sensor: This parameter displays the voltage drop across the transmission fluid temperature (TFT) sensor circuit. 5 volts is applied to the TFT sensor circuit. The sensor is a thermistor which changes internal resistance based on temperature. When the sensor is cold, the internal resistance is high, resulting in a high signal voltage. As the sensor warms, the internal resistance decreases, and the signal voltage will also decrease. A low signal voltage indicates a warm TFT, and a high signal voltage indicates a cold TFT.
Vehicle Speed Sensor: This parameter displays the speed at which the vehicle is traveling. The scan tool displays vehicle speed as kilometers per hour (km/h), miles per hour (mph). The vehicle speed is calculated based on the input signal from the vehicle speed sensor.
Reverse Inhibit Solenoid Command: This parameter displays the commanded state of the reverse inhibit solenoid. When the vehicle speed is greater than 5 km/h (3 mph), the solenoid is commanded ON, inhibiting shifts to Reverse. When the vehicle speed is less than 5 km/h (3 mph), the solenoid is commanded OFF, allowing shifts to Reverse. The scan tool will display ON/OFF.
Skip Shift Lamp Command: This parameter displays the commanded state of the skip shift lamp. The scan tool will display ON/OFF.
