Principles of Operation: Notes
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Smart Junction Box (SJB) may also be identified as the Generic Electronic Module (GEM).
The SJB sends a voltage signal to the wiper motor module in order to monitor the status of the wipers. When the headlamp control switch is in the AUTOLAMP position and the wipers are active, the SJB will activate the headlamps within 10 seconds. When the SJB detects that the wipers have been turned off, the SJB will turn off the headlamps after 30 seconds.
