This F150 has had 3 BCMs installed for the same problem. The hazard light come on for no reason, low brake fluid message, park brake on message, power locks don't respond to inside switches, all four door ajar messages on the dash, interior lights do not come on with door opening. The dealer replaced the first one last summer and then the second one under a parts warranty. These two lasted less than two days. Then they identified that there was water leaking into the vehicle through a hole in the lower edge of the windshield so refused any further warranty on the BCM. Truck sat since August 2020 til two weeks ago. I diagnosed it as a failed BCM again as the internal voltage for all of the pull down switch circuits is dead in the BCM. I checked voltage drops on the powers and grounds to the BCM and tested all circuits for shorts to grounds and voltage. I could find no problem. I installed a used BCM and programmed to the vehicle. It lasted 3 days and failed exactly the same way as the others. I removed both front seats, console and entire dash assembly to inspect for water damage and can find nothing wrong nor any signs of water entry to the cab area. There is one identical case on the Identifix and it was apparently fixed with the replacement of the BCM. I'm starting to lose my hair...
Here's part 2 and possibly a fix: • 2013 F150 BCM Failures...
