SCAN TOOL DATA DEFINITIONS

8-Digit GM Part Number: The scan tool displays the GM eight digit part number of the instrument panel cluster (IPC).

Air Bag Lamp: The scan tool displays On/Off. The state of the air bag lamp as commanded by the IPC. The IPC receives a class 2 message from the SDM.

Ambient Temperature: The scan tool displays 0-100 °C. The measured temperature from the ambient outside air temperature sensor to the IPC.

Antilock Lamp: The scan tool displays On/Off. The state of the antilock lamp as commanded by the IPC. The IPC receives a class 2 message from the EBCM.

Brake Lamp: The scan tool displays On/Off. The state of the brake lamp as commanded by the IPC. The IPC receives a class 2 message from the BCM.

DIC Mode Button: The scan tool displays On/Off. The state of the DIC mode button detected by the IPC from the DIC switch (low input).

DIC Reset Button: The scan tool displays On/Off. The state of the DIC reset button detected by the IPC from the DIC switch (low input).

Engine Oil Level: The scan tool displays OK/Low. The PCM monitors the signal circuit of the engine oil level switch, where an open switch is displayed as Low (low engine oil level).

Engine Oil Life: The scan tool displays 0-100%. The PCM calculates the remaining engine oil life.

Engine Oil Pressure: The scan tool displays OK/Low. The PCM monitors the signal circuit of the engine oil pressure switch, where an open switch is displayed as OK.

Fuel Level: The scan tool displays 0-100%. The PCM calculates the amount of fuel remaining in the tank based on the input from the fuel level sensor.

High Beam Lamp: The scan tool displays On/Off. The state of the high beam lamp as commanded by the IPC. The IPC receives a class 2 message from the BCM.

Ignition 0 (Data: The scan tool displays 0-25.5 volts. The voltage measured from the ignition 0 positive voltage circuit at the IPC.

Ignition 0 (Input): The scan tool displays On/Off. The state of the ignition 0 positive voltage circuit detected by the IPC when the ignition is turned ON.

Key In Ignition: The scan tool displays Active/Inactive. When the key is in the ignition switch, the scan tool will display Active.

Left Turn Signal: The scan tool displays On/Off. The state of left turn signal input detected by the IPC from the turn hazard flasher (high input). The indicator turns on when the switch is closed.

Low Brake Fluid: The scan tool displays OK/Low. The state of the low brake fluid input detected by the IPC from the brake fluid switch (low input).

Low Coolant Level: The scan tool displays OK/Low. The state of the low coolant level input detected by the IPC from the engine coolant level sensor (low input).

Low Washer Fluid: The scan tool displays OK/Low. The state of the low washer fluid input detected by the IPC from the washer fluid switch (low input).

Odometer: The scan tool displays 0-999999.9 miles. The IPC calculates the mileage to determine the odometer value.

PROM ID: The scan tool displays the four digit number of the PROM incorporated into the IPC.

Revision Level: The scan tool displays the revision level of the software in the IPC.

Right Turn Signal: The scan tool displays On/Off. The state of right turn signal input detected by the IPC from the turn hazard flasher (high input). The indicator turns on when the switch is closed.

Seat Belt Lamp: The scan tool displays On/Off. The state of the seat belt lamp as commanded by the IPC. The IPC receives a class 2 message from the SDM.

Software Release Level: The scan tool displays the original release level of the software in the IPC.

TCS Off Lamp: The scan tool displays On/Off. The state of the TCS off lamp as commanded by the IPC. The IPC receives a class 2 message from the EBCM.

Trip Odometer Reset: The scan tool displays On/Released. The state of trip odometer reset switch detected by the IPC from the internal trip odometer reset switch.

Vehicle Speed: The scan tool displays 0-255 km/h (0-159 mph). The IPC obtains vehicle speed data from the PCM on a dedicated input. The PCM is responsible for calculating correct vehicle speed data.
