FORD 2010 E-450 v.3 - Manual (Page 161)

Performing the TPMS reset procedure (Vehicles that have wheels
with snap-in pressure sensors)
It is recommended that you read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes
and then park in a safe location where you can easily get to all four tires
and have access to an air pump.
2. Place the ignition in the off position and keep the key in the ignition.
3. Cycle the ignition to the on
position with the engine off.
4. Turn the hazard flashers on then
off three times. This must be
accomplished within 10 seconds.
If the reset mode has been entered successfully, the horn will sound
once, the TPMS indicator
will flash and the message center (if
equipped) will display TRAIN LEFT FRONT TIRE. If this does not
occur, please try again starting at Step 2.
If after repeated attempts to enter the reset mode, the horn does not
sound, the TPMS indicator
does not flash and the message center (if
equipped) does not display TRAIN LEFT FRONT TIRE, seek service
from your authorized dealer.
