Ignition 1: The scan tool displays On/Off. The IPC displays On if it senses voltage at the ignition 1 input.

Ignition 1: The scan tool displays 0-16 V. The IPC displays the voltage present at the ignition 1 voltage circuit.

Key In Ignition: The scan tool displays On/Off. The BCM monitors the key in ignition switch, where a closed switch is displayed as On (key is in the ignition). Last 4 Dig of GM Part #: The scan tool displays the last 4 digits of the GM part number of the IPC.

Low Coolant Lamp: The scan tool displays On/Off. The state of the low coolant indicator as commanded by the IPC. The IPC receives a class 2 message from the BCM indicating coolant level.

Low Coolant Level: The scan tool displays On/Off. The BCM monitors the low coolant level switch, where a closed switch is displayed as On (coolant is low).

Low Fuel Lamp: The scan tool displays On/Off. The state of the CHECK GAGES indicator as commanded by the IPC. The IPC receives a class 2 message from the BCM indicating fuel level percent.
