Volkswagen Golf Service & Repair Manual: Tyre pressure monitor
System description – Tyre Pressure Monitoring System
| 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. Event 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 with the help of the ABS
speed sensors. |
| After the following work or modifications, the tyre pressure
monitor display button -E492- must be pressed and held until a
confirmation is sounded. |
| Changing one or more wheels |
| Interchanging wheels, e.g. from front to rear |
| Removing and fitting one or more wheels |
| 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: |
| Insufficient tyre inflation pressure. |
| One-sided loading of vehicle |
| Increased load on one axle, e.g. due to towing a trailer |
| Temporary spare wheel installed |
| System fault in the ABS system |
|
|
|
| If a fault in the ABS is displayed by the ESP and TCS
warning lamp -K155- then the Tyre Pressure Monitoring System
warning lamp -K220- will also light up. However, no fault will
be stored in the system for the tyre monitor display. |
| The warning lamp cannot be erased. In this case, please
carry out the following steps: |
