Installing Wheel Electronics
Information
Every new set of wheels or wheel change must be communicated to the control unit. In particular, this is necessary when wheel positions have been interchanged. For this purpose, always select the tyre type and tyre size under Main menu > TPM > Tyre type in the instrument cluster. The control unit then learns the wheel positions again while the vehicle is driving.
- Clean the valve bore carefully (visual inspection)
.
Information
When replacing the wheel electronics:
- Always use completely new valves .
- Always use new bolts .
- Fit new
valve on the wheel electronics using a new
screw and insert it together into the valve bore, but do not tighten the screw yet.
Information
In order to avoid damage caused by twisting the valve body, the valve must be countered using an assembly pin (supplied with the new valve).
- Fit the washer from outside and screw on the union nut until it is seated correctly. Visibly screw in the bore at the valve foot and block it using the supplied assembly pin.
- Press the wheel electronics unit -1-
slightly into the rim bed (this adjusts the angle of inclination of the valve with respect to the wheel electronics unit).
