3.1 1701 Special Function and Test Codes
3.1.3 1701 Diagnostic Tests
Using the 1701 tests, you can diagnose the individual input or output devices
that connect to the DC control board.
Input devices are the various sensors, switches, and thermistors. When you
run a test, the DC control board monitors the input device and displays the
SENSING prompt. When you manually actuate the sensor, the beeper sounds
and the control panel lights up. Other input tests display only data or control
panel lights, requiring no manual interaction.
Output devices consist of motors, solenoids, and high-voltage power supplies.
When you run an output test, the device is turned on and off. If PASS message
is displayed, the DC control board received the expected sensor signal from the
device under test. To prevent device overheating, device test time is limited to
10 seconds.
