INPUT CIRCUIT TESTING
After diagnostics is entered, the status of input circuits can be viewed or monitored. If a failure occurs within an input circuit the controller will display a "?" for unknown values, a "OC" for an open circuit and a "SC" for a shorted circuit.
Use the following steps to view the inputs into the controller:
1. Enter the diagnostics mode.











2. Turn the knob until the test you are looking for appears.

3. To see the input, press the A/C or RECIRC button. The digits displayed will represent the input seen by the controller.
