Input Displays
When trouble shooting a malfunction, the ECM, BCM, or IPC input display can be used to determine if the switched inputs are properly interpreted. When 1 of the input tests is selected, the state of that device is displayed as "HI" or "LO". Basically, "HI" or "LO" represent the input terminal voltage for that circuit.
Also, the display indicates if the input changed state since it was last tested. If a change occurred, an "X" will appear next to the HI - LO indicator. If a change did not occur, an "O" will remain displayed. The "X" will only appear once per selected input.
