The procedure in the owners manual works! Thanks guys! FWIW... the seatbelt must be latched 3 times exactly. More or less and it won't work.
The procedure is as follows:
1) With engine switched off, latch the driver's seatbelt.
2) Start the truck.
3) Unlatch, Latch, Unlatch, Latch, Unlatch, Latch. This step must be completed within 10 seconds, start to finish, or it will not work.
4) Turn engine off. Tone will sound telling you the change has been made.
5) Unlatch the seatbelt; you are done.
Steps 2 - 4 must be completed within 60 seconds, start to finish, or it will not work.
You can turn the dinger back on by repeating the above procedure. DC does place a warning in the instructions for this saying that they do not recommend doing this.
