2005 Ford F-150 door locks

  • 2005 FORD F-150
  • V8
  • 4WD
  • 46,000 MILES
After the door locks are automatically locked by moving, the solenoid is activated, unlocking the doors.
Even when I relock them, they unlock and I can hear the solenoid clicking to continue to unlock the doors. This only happens when the truck is in gear.
It doesn't happen in Park with the engine running, or when I lock the doors with the engine off. This just started a week ago, I'm baffeled. This truck has a remote fob and keypad. What's going on, and how can I repair the problem?
Do you
have the same problem?

Pinpoint Test E: The Auto-lock Does Not Operate Correctly Normal Operation When autolock is enabled the vehicle security module reads inputs from: The ignition switch " The brake pedal position (BPP) switch " The door ajar switches (all doors closed) " The brake pedal position (BPP) switch and transmission range (TR) sensor inputs are received through the universal asynchronous receiver-transmitter (UART)-based protocol (UBP) communications network. Once the vehicle security module receives all 3 inputs the doors automatically lock. Possible Causes Circuit 344 (BK/YE) open " Circuit 345 (BK/PK) open " Circuit 346 (BK/WH) open (SuperCrew) " Circuit 363 (BK/LB) open (SuperCrew) " UART based protocol (UBP) communications network " Vehicle security module " Door ajar switches " PINPOINT TEST E: THE AUTO-LOCK DOES NOT OPERATE CORRECTLY E1 VERIFY THE AUTOLOCK FEATURE IS ENABLED Verify the autolock feature is enabled.
