Wiper Activated Headlamps (If Equipped with Autolamp System)
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The SJB sends a voltage signal to the wiper/washer module in order to monitor the status of the wipers. When the wipers are turned on, the wiper/washer module will pull the voltage down. Once the SJB detects a drop in voltage it will turn on the headlamps after 3 seconds. When the SJB detects the voltage raising, it will determine that the wipers have been turned off and the SJB will turn off the headlamps after 30 seconds.
