| Tyre pressure monitor (TPM) |
| For detailed information on the tyre pressure monitor (TPM), refer to → No.347. |
| The tyre pressure monitor system includes wheel electronics mounted on each wheel. |
| At regular intervals, the wheel electronics transmit data which the central locking and anti-theft alarm system aerial receives and forwards to the tyre pressure monitor control unit -J502-. |
| This control unit is integrated with its own diagnostic address into the convenience system central control unit -J393-. |
| The tyre pressure specifications (monitoring air pressures) are set in the control unit as factory defaults. |
| The pressures, noted on the tank flap sticker, are valid for a set of wheels with the Volkswagen-approved tyres. |
| The nominal tyre pressures for this set of wheels are specified for the partially and fully laden vehicle and must not be changed. |
