Summary
Vehicle description: Pickup trucks, crew cabs, utility trucks and sport utility vehicles. These vehicles were built with the polarity of the wiring for the zero adjust brake switch reversed from what was specified on the switch drawing. With the reversed polarity, the contacts in the brake switch can wear out prematurely. The brake switch will perform normally until the brake switch contacts wear out, resulting in loss of the brake lamps without any warning to the driver.
Actions
Dealers will replace the brake switch and reverse the wiring.
