Principles of Operation: Notes
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 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).
If equipped with automatic headlamps, the SJB will illuminate the exterior lamps, including the parking lamps, when the front wipers are on for more than 3 seconds and the headlamp control is in the AUTOLAMP position. When the wipers are turned off, the exterior lamps will remain on for 30 seconds before turning off.
