Ambient Temperature Sensor

The scan tool displays 0-100°C. The measured temperature from the ambient outside air
temperature sensor to the powertrain control module (PCM.

Balance

The scan tool displays 0-100%. The amount of left to right balance selected.

Battery Voltage

The scan tool displays 0-19 volts. The voltage measured at the battery positive voltage
circuit of the instrument panel cluster (IPC).

Battery Voltage

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

Battery Voltage Signal

The scan tool displays 0-19 volts. The battery voltage as monitored by the body control
module (BCM).

Cargo Lamp Switch

The scan tool displays Active or Inactive. The BCM monitors the signal circuit of the cargo
lamp switch. A closed switch is displayed as Active.

Courtesy Lamp Output

The scan tool displays the commanded state of the courtesy lamp relay. The scan tool
displays On when the BCM allows the courtesy lamp relay to go to ground to activate the
courtesy lamps.

Courtesy Lamp Switch

The scan tool displays Active or Inactive. The BCM monitors the signal circuit of the
courtesy lamp switch. A closed switch is displayed as Active.

Cruise Control Active

The scan tool displays Yes or No. The state of the cruise control indicator as commanded by

the powertrain control module (PCM).

Displayed Fuel Level

The scan tool displays 0-100%. The displayed fuel gage value in the IPC. This value may
slightly differ from the monitored fuel level.

Driver Door Ajar Switch

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

Driver Seatbelt

The scan tool displays Unbuckled or Buckled. The state of the fasten safety belt indicator as
commanded by the BCM.

ECT Sensor

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

Engine Coolant Temperature

The scan tool displays 38°C-128°C (100°F-260°F). The displayed coolant temperature gage
value in the IPC. This value may slightly differ from the monitored coolant temperature.

Engine Oil Level Switch

The scan tool displays OK or Low. The PCM monitors the signal circuit of the engine oil
level and temperature sensor. A closed switch is displayed as Low with low engine oil level.

Engine Oil Pressure Switch

The scan tool displays OK or Low. The PCM monitors the signal circuit of the engine oil
pressure switch. A closed switch is displayed as Low with low engine oil pressure.

Engine Oil Temperature Calculated

The scan tool displays Celsius (Fahrenheit). This is a calculated value of the engine oil as
determined by the PCM.
