- [10208141](https://open.wenmarpro.com/bulletins/10208141), 2022-02-23: Some 2020\-2022 F\-Super Duty vehicles may exhibit a condition where the engine will not turn off and/or have various electrical symptoms including a dead battery, horn stays on and no crank/no start. The vehicle may also have an illuminated anti\-lock braking system \(ABS\) indicator with diagnostic trouble codes \(DTCs\) C0020 and U3003 in the ABS module. The vehicle may not shift out of park \(P\) and/or have continuously illuminated brake lamps with DTCs P0504 and/or C0040. This may be a result of water/moisture intrusion into the battery junction box \(BJB\). The BJB is located under the hood of the vehicle. This water/moisture intrusion may be related to the BJB cover not installed completely or broken cover tabs/locking fingers allowing water/moisture into the BJB. To correct the condition, follow the Service Procedure steps to inspect for water/moisture intrusion into the BJB and replace the BJB if water/moisture intrusion is found.
