ECT: The scan tool displays -40-151°C (-40-304°F). The PCM monitors the voltage at the signal circuit of the engine coolant temperature sensor. The voltage is inversely proportional to the engine coolant temperature.
Fasten Seat Belts: The scan tool displays On/Off. The state of the fasten safety belt indicator as commanded by the IPC.
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.
Hi Beam Lamp: The scan tool displays On/Off. The state of the high beam indicator as commanded by the IPC.
Ignition 1: The scan tool displays Active/Inactive. The BCM displays Active if it senses voltage at the ignition 1 input.
Ignition 3: The scan tool displays Active/Inactive. The BCM displays Active if it senses voltage at the ignition 3 input.
Key In Ignition: The scan tool displays Active/Inactive. The BCM monitors the key in ignition switch, where a closed switch and the key in the ignition is displayed as Active.
Left Turn Signal: The scan tool displays On/Off. The BCM monitors the left turn signal switch, where a closed switch is displayed as On.
Low Fuel Lamp: The scan tool displays On/Off. The IPC receives a class 2 message from the PCM requesting illumination.
Monitored Coolant Temp: The scan tool displays 40°F-419°F (40°C-215°C). The IPC monitored coolant temperature data as provided by the PCM via the class 2 serial data link.
Monitored Fuel Level: The scan tool displays 0-100%. The IPC monitored fuel level percent as provided by the PCM via the class 2 serial data link.
Overspeed Lamp: The scan tool displays On/Off. The state of the overspeed indicator as commanded by the IPC.
Park Brake Switch: The scan tool displays On/Off. The BCM monitors the park brake switch signal circuit, where a closed switch and the park brake engaged is displayed as On.
Park Lamps: The scan tool displays On/Off. The state of the park lamps as commanded by the BCM.
Park Switch: The scan tool displays Open/Closed. The state of the park position switch, where a closed switch and the shifter in park is displayed as CLOSED.
PRNDL State: The scan tool displays the PRNDL state as provided to the IPC from the PCM via the class 2 serial data link.
PROM ID: The scan tool displays a 4 digit number that the identifies the PROM of the IPC.
Right Turn Signal: The scan tool displays On/Off. The BCM monitors the right turn signal switch, where a closed switch is displayed as On.
Security Lamp: The scan tool displays On/Off/Flashing. The state of the security indicator as commanded by the IPC.
