Issue:
Some 2021-2023 F-150 vehicles may exhibit a no crank/no start with an excessive battery draw and air conditioning (A/C) clutch engaged at all times. This may be due to an open diode in the A/C clutch damaging the output driver field effect transistor (FET) in the body control module C (BCMC). To correct the condition, follow the Service Procedure to replace the BCMC and A/C clutch disc and hub assembly.
Action:
Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
•
