monitored fuel level in the PCM.

Displayed Odometer

The scan tool displays 0 to 999999 miles (0 to 999999 kilometers). The scan tool displays the data on the
odometer in the IPC.

Displayed Trans Oil Temp

The scan tool displays 29-157°C (84-315°F). This is the displayed transmission oil gauge data. The data
may differ from the monitored trans oil temperature from the PCM.

Displayed Trip Odometer

The scan tool displays 9999.9 miles (9999.9 kilometers). The scan tool displays the data on the trip
odometer in the IPC.

Driver Door Ajar Switch

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

ECT

The scan tool displays -39 to +140°C (-38 to +284°F). This is the engine coolant temperature as
monitored by the PCM.

Elapsed Time (Hours)

The scan tool displays 00 to 99 Hours. The DIC begins to calculate elapsed time when Elapsed Time is
displayed on the DIC and the RESET button is pressed.

Elapsed Time (Minutes)

The scan tool displays 00 to 59 Minutes. The DIC begins to calculate elapsed time when Elapsed Time is

displayed on the DIC and the RESET button is pressed.

Elapsed Time (Seconds)

The scan tool displays 00 to 59 Seconds. The DIC begins to calculate elapsed time when Elapsed Time is
displayed on the DIC and the RESET button is pressed.

Engine Oil Level Switch

The scan tool displays OK or Low. This is the state of the engine oil level switch as monitored by the
PCM. A closed switch is displayed as OK.

Engine Oil Life Remaining

The scan tool displays 0-100 percent. This is the engine oil life index that is calculated and maintained by
the PCM.

Engine Oil Pressure Sensor

The scan tool displays 0 to 5 volts. The PCM monitors the engine oil pressure sensor signal circuit where
a low voltage indicates low pressure.

Engine Speed

The scan tool displays 0-9999 RPM. Engine speed is computed by the PCM from the 3X reference input.
It should remain close to desired idle under various engine loads with the engine idling.

Engine Speed

The scan tool displays 0- 9999 RPM. The IPC receives the engine speed from the PCM via the engine
speed signal circuit.

Fade

The scan tool displays -50 to +50. The Fade between the front and rear audio output.

Fasten Seat Belt

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

Fuel Capacity

The scan tool displays gallons. The DIC receives a class 2 message from the PCM indicating the fuel
capacity.

Fuel Level Sensor

The scan tool displays 0-5 volts. The PCM monitors the fuel level sensor signal circuit where 0 V is an
empty tank.

Fuel Level Sensor Rear

The scan tool displays 0-5 volts. The PCM monitors the rear tank fuel level sensor signal circuit where 0
V is an empty tank.

Fuel Tank Level Remaining

The scan tool displays gallons (liters). This is the amount of fuel remaining in the fuel tank as determined
by the PCM.

Fuel Tank Level Remaining

The scan tool displays 0-100%. The scan tool displays in percentage the amount of fuel remaining in the
fuel tank as determined by the PCM.

Fuel Tank Rated Capacity

The scan tool displays gallons (liters). This is the fuel tank rated capacity as determined by the PCM.

Headlamp Relay Feedback

The scan tool displays On or Off. This is the state of the headlamp and the panel dimmer switch. The scan
tool displays On when the headlamp and the panel dimmer switch is turned On or in auto position with
the ambient light sensor in its dark state.

Hi Beam Lamp

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

High Beam Switch

The scan tool displays On or Off. This is the position of the high beam switch where an active switch is
displayed as On.

Hood Ajar Switch

The scan tool displays Active or Inactive. The BCM monitors the signal circuit of the hood ajar switch.
An open switch is displayed as Active with the hood open.

Hourmeter

The scan tool displays 0-10,000 hours. This is the PCM accumulated engine run time hours provided to
the IPC via the class 2 serial data link.

Ignition 1

The scan tool displays Active or Inactive. The scan tool displays Active when the ignition switch is in the
RUN or CRANK position

Ignition 3

The scan tool displays Active or Inactive. The scan tool displays Active when the ignition switch is in the
RUN position only.

Ignition 1 Signal

The scan tool displays 0-16 volts. The ignition 1 signal represents the system voltage detected by the
PCM at the ignition voltage circuit.

Ignition Voltage

The scan tool displays the vehicle ignition voltage at the DIC ignition voltage circuit.

Illumination Input Volt

The scan tool displays 9-16 volts. The illumination input voltage is the ignition monitored voltage at the
instrument panel lamp supply voltage circuit at the DIC.

Key In Ignition

The scan tool displays Yes or No. The BCM monitors the signal circuit of the ignition key alarm switch.
The scan tool displays Yes when the ignition key is fully inserted into the ignition switch cylinder.

Left Rear Cargo Door Ajar Switch

The scan tool displays On or Off. The BCM monitors the signal circuit of the left rear cargo door ajar
switch. An open switch is displayed as On with the door open.
