Here is a web page with a review and a helpful schematic diagram:
AS312 (AM312) Mini PIR module review

A 20K resistor on the output pin -- may be enough to bring E9 into play, most of the sensor's output pin drive capability would be neutered there. Changing the resistor (or shorting or bypassing it) will prove or disprove the theory.
