When vehicles are operated in high contamination/corrosion environments associated with road salt use, moisture and debris can enter through the BJB cover and base, potentially leading to corrosion of the relay and fuse terminals, especially at the front of the box. Corrosion in the battery junction box may result in a variety of symptoms, including a loss of certain vehicle functions, such as the loss of low beam headlamps, loss of high beam headlamps, or vehicle no start.
