Optimizing Tyre Pressure Monitor Display for Polo Mk5

Tyre pressure monitor display
Tyre pressure monitor display
The tyre pressure monitor display system is part of the software in the ABS control unit -J104-. The system is used to detect slow tyre pressure loss from a wheel. Fault memory entries for the tyre pressure monitor display are stored in the ABS control unit -J104-. The tyre pressure monitor display compares the wheel speeds and consequently the rolling circumferences of the individual wheels via the ABS sensors.
After the following work or modifications, the tyre pressure monitor display button -E492- must be pressed and held until a confirmation is sounded.
t  Change in tyre pressure
t  Changing one or more wheels
t  Interchanging wheels, e.g. from front to rear
A change in a wheel's rolling circumference will be indicated by the tyre pressure monitor warning lamp -K220- lighting up in the dash panel insert. A tyre's rolling circumference may change as a result of:
t  Insufficient tyre inflation pressure
t  Structural tyre damage
t  One-sided loading of vehicle
t  Increased load on one axle, e.g. due to towing a trailer
t  Use of snow chains
t  Temporary spare wheel installed
t  Wheel renewal
System fault in the ABS system
   
If a fault in the ABS is displayed by the ESP and TCS warning lamp -K155- or the traction control system warning lamp -K86-, then the tyre pressure monitor warning lamp -K220--arrow- will also light up. However, no fault will be stored in the system for the tyre monitor display.
The warning lamp cannot be extinguished by pressing the TPM button -E492-. In this case, please carry out the following steps:
–  Connect vehicle diagnosis, testing and information system -VAS 5051- and select “Guided fault finding” → Vehicle diagnosis, testing and information system VAS 5051.
