High Coolant Temp Lamp: The scan tool displays On/Off. The state of the engine coolant temperature indicator as commanded by the IPC.

Ignition 0: The scan tool displays On/Off. The IPC displays On when the IPC detects voltage at the ignition 0 voltage circuit.

Ignition 0: The scan tool displays 0-16 V. The IPC displays the voltage present at the ignition 0 voltage circuit.

Illumination Dimming: The scan tool displays 0 - 16 V. The IPC displays the voltage present at the instrument panel lamp supply voltage circuit.

Key in Ignition: The scan tool displays Yes/No. The BCM monitors the ignition key alarm switch, where a closed switch is displayed as Yes (key is in the ignition).

Oil Level Lamp: The scan tool displays On/Off. The state of the LOW OIL indicator as commanded by the IPC.

Oil Life Lamp: The scan tool displays On/Off. The state of the CHANGE OIL indicator as commanded by the IPC.

Oil Life/TIM Reset Switch: The scan tool displays On/Off. The BCM monitors the oil life/tire pressure monitor reset switch, where a closed switch is displayed as On (switch is pressed).

Oil Pressure Lamp: The scan tool displays On/Off. The state of the engine oil pressure indicator as commanded by the IPC.

Park Brake Switch: The scan tool displays On/Off. The BCM monitors the park brake switch, where a closed switch is displayed as On (park brake engaged).

Park Lamp input: The scan tool displays Active/Inactive. The BCM monitors the headlamp switch, where a closed switch is displayed as On.

Parking Lamps: The scan tool displays On/Off. The IPC displays the park lamp status as indicated the BCM. The IPC receives a class 2 message from the BCM indicating that the park lamps are on.

Seat Belt Lamp: The scan tool displays On/Off. The state of the fasten safety belt indicator as commanded by the IPC.

Seatbelt: The scan tool displays Buckled/Unbuckled. The BCM monitors the LF seat belt switch, where a closed switch is displayed as Buckled (seat belt is buckled).
