Power Door Locks

You know how the door locks cycle to lock the doors when the truck reaches 5mph? This function has suddenly stop working on my truck. I tried the procedure to disable/enable this feature using the keypad on the drivers door to no joy. Is there anything else I could try?

When you do the enable procedure from the keypad, do you get a horn chirp followed by a honk (indicating the feature has been successfully enabled)? Have you tried the procedure using the interior lock buttons?

Code:
Power door unlock/lock procedure
You must complete Steps 1–5 within
30 seconds, or the procedure will
have to be repeated. If the
procedure needs to be repeated,
you must wait a minimum of 30
seconds to begin again.
1. Turn the ignition to the 3 (ON)
position, then press the unlock control
three times.
2. Turn the ignition to the 1 (OFF/LOCK) position, then press the unlock
control three times.
3. Turn the ignition to the 3 (ON) position; the horn will chirp to
indicate the driver configuration mode has been activated.
4. Within five seconds, press unlock then the lock control. Note: One horn
chirp should be heard, indicating the system has been disabled.
Conversely, a horn chirp followed by a honk will indicate the system is
enabled. Pressing the unlock control then the lock control will turn the
feature ON if it was previously OFF, or OFF if it was previously ON. The
horn will chirp once if autolock was deactivated or twice (one short
chirp and one long honk) if autolock was activated.
5. Turn the ignition to the 1 (OFF/LOCK) position to exit programming.
Note: After exiting the driver configuration mode, the horn will chirp
once to indicate a feature has been activated/deactivated.

Problem resolved! I looks like the problem was the brake switch. The brake switch is used by the auto look feature to determine when the brake is released. As soon as the switch was replaced, the auto lock began working again.
