Scan Tool Data Definitions

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Clutch Pedal 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.

Transmission Fluid Temperature (TFT) Sensor: This parameter displays the input signal of the transmission fluid temperature (TFT) sensor. The TFT is high 151°C (304°F) when signal voltage is low, 0 V, and the TFT is low -40°C (-40°F) when signal voltage is high, 5 V.

Vehicle Speed: 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.
