Workshop notes
Wheel with internal sensor
64
– Note ID of external sensor (engraved on top of the housing) and its position
on the vehicle, e.g. rear axle left, outside.
Alternative: Fix a plate with the description of the location to each external
sensor.
– Loosen the union nut of the PA tube on the tire valve.
– Pull the PA tube from the valve.
– First unscrew only those wheel nuts that fasten the external sensor.
– Remove external sensor completely, together with the PA tube.
Do not turn the PA tube at the external sensor and do not remove the PA
tube from external sensor unnecessarily.
Prevent dirt from entering into the PA tube.
– Check the PA tube for any damage.
– Replace the PA tube if ageing ruptures or rubbing wear is visiblesee
chapter 10.2.4 "Replacing PA tubes (external sensor)", page 65.
– Remove the remaining wheel nuts.
– Change the wheel or tire.
– Fit the wheel or wheels again.
– Fix the wheel or wheels with a few wheel nuts to the wheel bolt to which
neither the external sensor nor the weight plate will be mounted.
While assembling the wheel make sure that the tire valve gets its original
position.
With twin tires, the tire valves should be placed in opposite position.
– Place the respective external sensor to its original position and fix it with
wheel nuts.
With individual wheels, assemble the counterweight in the opposite of the
external sensor.
– Screw the union nut of the hose back on to the tire valve.
– Tighten union nuts manually only.
– Check that the connection is tight using a leakage indicating spray.
– Tighten the wheel nuts crosswise according to the vehicle manufacturer's
specifications.
When changing a wheel with the internal sensor it must be ensured that the new
wheel is also equipped with such and internal sensor. If this is not the case, the
internal sensor must be installed in the new wheelsee chapter "6.3 Assembly
of the internal sensor" on page 40.
For start-up, the new ID of this internal sensor must be learned. For this
purpose that Diagnostic Software must be opened.
"Module configuration" parameter setting
– Enter the new ID of the respective wheel position directly of carry out a free
assignment under Module assignmentsee chapter "6.3 Assembly of the
internal sensor" on page 40.
