Summary
Some 2018 F-150 and Expedition vehicles may exhibit a battery draw resulting in a discharged battery. An electronic park brake (EPB) switch internal short may cause the anti-lock brake system (ABS) module to wake up resulting in controller area network (CAN) system wake up. If the draw cannot be duplicated with fuse F70 removed, suspect the EPB switch.
