Scan Tool Data Definitions

This is the voltage present at the battery positive voltage circuit of the instrument panel cluster (IPC).

The scan tool displays On or Off. This is the status of the Change Engine Oil Indicator as commanded by the radio.

The scan tool displays On or Off. This is the status of the chime producer as commanded by the IPC.

The scan tool displays Yes or No. This is the status of the cruise control switch as commanded by the PCM/ECM.

The scan tool displays Door Closed or Door Ajar. This is the status of the driver's door switch as commanded by the BCM.

The scan tool displays -40 to +151°C (-40 to +304°F). The PCM/ECM monitors the voltage at the signal circuit of the engine coolant temperature sensor. The voltage is inversely proportional to the engine coolant temperature.

The scan tool displays OK or Low. The status of the engine oil level switch as monitored by the ECM. The ECM monitors the signal circuit of the engine oil level switch.

The scan tool displays 0-100%. The PCM/ECM calculates the amount of engine oil life remaining.

The scan tool displays kPa (psi). The scan tool displays the current engine oil pressure as calculated by the ECM.

The scan tool displays volts. The scan tool displays the current engine oil pressure sensor voltage as calculated by the ECM.

The scan tool displays OK or Low. The status of the engine oil pressure switch as commanded by the PCM. The PCM monitors the signal circuit of the EOP switch.

The scan tool displays Celsius (Fahrenheit). The scan tool displays the engine oil temperature as calculated by the ECM.

The scan tool displays 0-9999 RPM. Engine speed is computed by the PCM/ECM. It should remain close to desired idle under various engine loads with the engine idling.

The scan tool displays 0-5 volts. The scan tool displays the voltage present at the signal circuit of the fuel level sensor as monitored by the PCM/ECM.

The scan tool displays 0-100%. The PCM calculates the amount of fuel remaining in the fuel tanks based on the signal circuit voltage of the fuel level sensor.

The scan tool displays On or Off. This is the status of the charge indicator as commanded by the PCM.

The scan tool displays volts. This is the ignition 1 input voltage to the PCM/ECM.

The scan tool displays On or Off. The scan tool displays ON when there is voltage present at the ignition accessory signal circuit of the PCM/ECM.

The scan tool displays On or Off. This is the status of the vehicle ignition as monitored by the BCM.

The scan tool displays Yes or No. The BCM monitors the signal circuit of the key in ignition switch. The scan tool displays a closed switch as Yes.

The scan tool displays On or Off. This is the status of the engine oil pressure indicator as commanded by the ECM.

The scan tool displays On or Off. This is the status of the engine oil level indicator as commanded by the ECM. The ECM monitors the signal circuit of the engine oil level switch.

The scan tool displays OK, High or Low. This is the history of the MIL circuit as monitored by the PCM.

The scan tool displays OK, High or Low. This is the status of the MIL circuit as commanded by the PCM/ECM.

The scan tool displays On or Off. This is the status of the MIL indicator as commanded by the PCM.

The scan tool displays km/h (mph). This is the vehicle non-driven wheel speed as monitored by the PCM.

The scan tool displays the current mileage of the vehicle as stored in the BCM.

The scan tool displays On or Off. This is the status of the park lamp switch as monitored by the BCM.

The scan tool displays On or Off. This is the status of the reduced engine power indicator as monitored by the PCM.

The scan tool displays Incomplete/Short to Gnd/Open/Short to B+/Ok. This is state of the vehicle speed signal circuit as monitored by the ECM.

The scan tool displays 0-255 km/h (0-155 mph). This is the vehicle speed as calculated by the PCM/ECM.
