SCAN TOOL DATA DEFINITIONS

4WD

The scan tool displays On or Off. This is the state of the 4WD indicator as commanded by the instrument
panel cluster (IPC).

ABS Lamp

The scan tool displays On or Off. This is the state of the ABS indicator as commanded by the IPC.

Annual Mileage

The scan tool displays 0.0 to 999999.9 miles (0.0 to 999999.9 kilometers). The DIC determines annual
mileage travelled from the 4 kppm vehicle speed signal circuit from the PCM.

Balance

The scan tool displays 0-100%. The Balance between the right and left audio output.

Battery

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

Battery Voltage

The scan tool displays 0-18 volts. This is the voltage at the battery positive voltage circuit of the BCM.

Battery Voltage

The scan tool displays 0-19 volts. The battery voltage as monitored by the IPC.

2004 ACCESSORIES & EQUIPMENT Instrument Panel, Gauges, and Console - Hummer H2

The scan tool displays 0-18 volts. The voltage measured from the radio or amplifier's ignition positive
voltage circuit to ground.

Brake Assist

The scan tool displays Active or Inactive. This is the state of the brake assist as monitored by the IPC.

Brake Lamp

The scan tool displays On or Off. This is the state of the BRAKE indicator as commanded by the IPC.

Business Trip Avg Speed

The scan tool displays 0.0 to 999.9 mph (0.0 to 999.9 km/h). The DIC calculates the average speed from
the business trip distance and time.

Business Trip Fuel Used

The scan tool displays 0.0 to 9999.9 gallons (0.0 to 9999.9 liters). The DIC calculates the business trip
fuel used based on the class 2 message from the PCM.

Business Trip Mileage

The scan tool displays 0.0 to 999999.9 miles (0.0 to 999999.9 kilometers). The distance traveled is
determined using the 4 kppm vehicle speed signal circuit from the PCM.

Business Trip Percent

The scan tool displays 0 to 100%. The DIC calculates the business trip percent of annual mileage from
the total business mileage travelled and the annual mileage travelled.

Cargo Door Ajar Switch

The scan tool displays Open or Closed. The BCM monitors the signal circuit of the cargo door ajar
switch. An open switch is displayed as Open with the door open.

Cargo Lamp On

The scan tool displays On or Off. This is the state of the cargo lamp as commanded by the IPC.

Cargo Lamp Switch

The scan tool displays On or Off. The scan tool displays On when the cargo lamps are requested from the
switch.

2004 Hummer H2

2004 ACCESSORIES & EQUIPMENT Instrument Panel, Gauges, and Console - Hummer H2

The scan tool displays On or Off. This is the state of the change engine oil indicator as commanded by the
IPC.

Check Coolant Temp

The scan tool displays On or Off. This is the state of the check coolant temperature indicator as
commanded by the IPC.

Check Engine Oil Level

The scan tool displays On or Off. This is the state of the check engine oil level indicator in the message
center as commanded by the IPC.

Check Engine Temp

The scan tool displays On or Off. This is the state of the check engine temperature indicator as
commanded by the IPC.

Chime Type

The scan tool displays None, Headlamp, Turn Signal, Key in Ignition, Seat Belt, or Park Brake. The
selected condition that produces the chime is displayed.

Coolant Level Switch

The scan tool displays OK or Low. The PCM monitors the coolant level switch signal circuit and a closed
switch is displayed as OK.

Cruise Control

The scan tool displays On or Off. The state of the cruise control indicator as commanded by the IPC.

Cumulative Fuel

The scan tool displays gallons (Liters). The DIC receives a class 2 message from the PCM indicating the
cumulative fuel gallons (liters).

Dimming

The scan tool displays Inactive or Active. Inactive is displayed when the PRNDL and the odometer or trip
odometer vacuum florescent display cannot be dimmed from the dimmer switch. Active is displayed
when the PRNDL and the odometer or trip odometer vacuum florescent display can be dimmed from the
dimmer switch in the IPC.
