Scan Tool Data Definitions

The scan tool displays Yes or No. The powertrain control module (PCM) monitors the cruise engaged signal circuit. The cruise control module provides a ground on the cruise engaged signal circuit when the cruise control system is active. An active cruise control system is displayed as Yes.

The scan tool displays On or Off. The PCM the monitors the cruise control on switch signal circuit. A closed switch is displayed as On.

The scan tool displays On or Off. The PCM the monitors the cruise control s resume/accel switch signal circuit. A closed switch is displayed as On.

The scan tool displays On or Off. The PCM monitors the cruise control set/coast switch signal circuit. A closed switch is displayed as On. The cruise control On/Off switch must be switched On in order to correctly view the Cruise Set/Coast Switch parameter.

The scan tool displays 0 to 9,999 RPM. The PCM monitors the crankshaft position (CKP) signal circuit in order to determine the engine RPM.

The scan tool displays Applied or Released. The PCM monitors the stoplamp switch signal circuit. A closed switch is displayed as Applied.

The scan tool displays Volts. This is the voltage at the stoplamp switch signal circuit, as monitored by the PCM.

The scan tool displays Active or Inactive. When the PCM receives a class 2 signal from the Electronic Brake Control Module (EBCM) requesting a traction control related function, the scan tool displays Active.

The scan tool displays 0 to 150 km/h (93.2 mph). The PCM monitors the vehicle speed sensor signal circuit in order to calculate the vehicle speed for display.
