Official summary
Some 2018 F-150, Expedition, and Navigator 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.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
