Conditions To Clear

Cycle Code 31 will be clear if the voltage at the SENSE LOW input, DERM terminal A6, is within a specific range of 36-VLR output voltage for 500 milliseconds.

NOTE: Test numbers refer to test numbers on diagnostic chart. For circuit number identification, see WIRING DIAGRAM S.

Checks if DERM has set Code 31 falsely.
Checks if 36-VLR voltage is available at the arming sensor.
Checks if fault is an open in the arming sensor or a poor connection to the arming sensor.
