My doors don't lock anymore when I put my truck into gear after I start the truck.

Before they would lock automatically, does anyone here know how I would trouble shot this as I have no owner's manual. It would be helpful if someone new what fuse/relay this function is.
Thanks

 

My truck locks with the engine start feature of an alarm from Ford.
When it doesn't lock after the engine is started, it is either door open, or dome light on.

Probably not your case, but it is worth a check.

Good luck,

Mike

 

You may want to try to activate the feature again.
The fuse/relay location is 8.... it is a 15 A fuse.

Deactivating / Activating the autolock feature

Before following the procedure, make sure that the ignition is OFF and all vehicle doors are closed.
You must complete steps 1 - 7 within 30 seconds or the procedure will have to be repeated.
If the procedure has to be repeated you must wait 30 seconds.

1. Turn the ignition key to ON.
2. Press the power door unlock control three times.
3. Turn the ignition key from ON to OFF.
4. Press the power door unlock control three times.
5. Turn the ignition back to ON. The horn will chirp.
6. Press the unlock control, then press the lock control. The horn will chirp once if autolock was deactivated or twice ( one short and one long chirp ) if autolock was activated.
7. Turn the ignition to OFF. The horn will chirp once to confirm the procedure is complete.
