direction before rotating the wheel
(also in a clockwise direction) to
mount the tire. Use this procedure on
both the upper and lower tire beads
(see Figure 5).
• Rotating tool tire changers: Position
the wheel on the changer so that the
sensor valve stem is approximately
210 degrees from the head of the
changer in a clockwise direction from
the mounting end of the tool (see
Figure 6). Make sure the sensor is
clear of the lower bead breaker area
to avoid damaging the sensor when
the breaker rises. Rotate the tool in a
counterclockwise direction to mount
the tire. Use this procedure on both
the upper and lower tire beads.
5) Adjust air pressure to specifcation.
Make sure the original style valve stem
cap is securely installed to keep moisture
out of the sensor. Install the wheel and
tire assembly on the vehicle.
6) Once the vehicle has remained
stationary for more than 20 minutes,
drive the vehicle for a minimum of 10
minutes while maintaining a continuous
speed above 15 mph (24 km/h). During
this time, the system will learn the new
sensor ID code and will clear any DTCs
automatically. If a sensor cannot be
trained, see appropriate manufacturer
service information. ■

* Over-torquing the sensor nut by as
litle as 106 in.-lbs. (12 N.m) may result
in sensor separation from the valve stem.
Under this condition, the sensor may
still function; however, the condition
should be corrected immediately.
