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.

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
