The system it self detects a problem. From the wiring to the alarm horn to the module. But on mine I found that one of the reverse sensors were bad. It had a small chip in it. Went to Ebay and got one for about $35 and replaced it (or just interchange it until the light goes out). No tools to remove it just open up the flexable tabs with your fingers and pull it threw the back. hope this helps you.
Motion detector alarm systems operate by using light sources. A beam of light is aimed at the light sensor and anyone who passes causes the sensor to register.

Your sensor is probably broken. You to need have diagnosed which sensor. Mine was damaged when lower assembly was replaced. Looks like Rock auto was cheapest.

When the LED light on an aftermarket alarm stays on, it means that the alarm is active. The light generally shows that the alarm status is "ready."
The alarm box controls the shutdown of the vehicle when it gets too hot by using information from a temperature sensor. The CDI will shut down. It also controls the red warning light.
It depends on what kind of alarm you have. For my alarm, a red light is on.
Your Windstar is subject to a Ford recall for the cause of this problem.The cause is a leaking brake pressure sensor screwed into the bottom of the master cylinder.I would suggest contacting your Ford dealer confirm your van is covered (I believe every single Windstar is part of the recall), and arrange for the quick and easy repair.See "Related Questions" below for more
