Keep Alive Power (KAPWR)

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The KAPWR circuit supplies a constant battery voltage (B+) input to the powertrain control module (PCM) to maintain memory contents when the ignition is in the OFF position.
