DESCRIPTION
The Beru sensors used on Prevost vehicles to monitor tire pressure (TPMS system) are being replaced by
new Huf sensors and their corresponding stainless valves stems.
Since the older and newer sensors are using different valve stems, replacement of a defective sensor on
older vehicles will require the use of a new kit number (valve stem and sensor assembly).
The table below provides a quick overview between the older and newer part numbers depending on
wheel application. Replacement and complementary part numbers are also provided.
NOTE
Older valve stem numbers are still available when the old sensor is not defective.
It must be noted that for the new style sensor to work with the existing vehicle TPMS system, a firmware
update must be done to the vehicle TPMS ECU and that the sensors ID# must be modified manually
through the TPMS screen in the vehicle. The procedure below provides step by step instructions required
to perform these modifications along with links to the downloadable ECU update file.
NOTE
-The ECU firmware update will only need to be loaded once on the vehicle.
-Old sensor ID# modification will only need to be done once on the vehicle.
-Every time a new sensor type will be installed, its ID# will have to be modified following the instructions
below.
-New and old sensors can be installed on the same vehicle.

DANGER
Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition
switch to the OFF position, the battery master switch to the OFF position and trip the main circuit
breakers equipped with a trip button.
RISK OF ELECTRICAL SHOCK
1. The alternator is connected to the batteries through master relay R1. If the ignition switch is in the
OFF position and the battery master switch (master cut-out) is set to the OFF position, there should
not be electrical power to the alternator terminals. However, a faulty master relay R1 could
eventually leave the battery power circuit closed, thus electrical power would be present at the
alternator terminals.
2. Using a multimeter, probe the alternator B1+ terminal and the ground terminal. Make sure that the
voltage reading is 0 volt prior disconnecting the alternator cables.
GAINING ACCESS TO THE ALTERNATORS
3. Loosen bolt A.

13. Using
gloves,
manually
rotate
the
turbocharger sector gear back and forth
(counterclockwise and clockwise) (FIGURE 10).
It should be noted that when the sector gear is
at the end of travel, or at an end stop, it can
require significant force to overcome friction
then, start its motion in the opposite direction.
This is normal and not cause for concern.
Apply more force to move the sector gear.
Once in motion, the sector gear movement
should be smooth, without binding or sticking
until it reaches its end of travel (end stop).

lbf (3 Nm)
b) tighten the screws in the pattern shown to: 97 in‐
lbf (11 Nm)
Once properly torqued, apply torque seal
FIGURE 19
23. Turn the ignition key back ON. Using the on screen directions in VCADS Pro, complete the final step
of the VGT calibration procedure. If the actuator is installed correctly, the procedure indicates a
successful VGT calibration with a green check mark.
The SRA runs from full open to close nozzle positions to ensure proper calibrated SRA travel.
If the calibration fails, either the pre‐positioning of the actuator drive gear is incorrect, the sector
gear positioning is incorrect, the actuator is faulty or the turbocharger sector gear and nozzle ring
mechanism is damaged. Turn OFF the ignition switch when done.
24. If the actuator is suspected of being faulty and requires replacement, follow the preceding
installation steps with the new actuator.
25. Connect the coolant lines to the actuator and
tighten the fittings (FIGURE 20).
