General description
The tire pressure monitoring system (TPMS) consists of an control unit (ECU)
with 4 LF antennas. The TPMS transmitter is mounted on the valve stem of the
tire. The RF receiver is integrated on the ECU.
The ECU contains the driver circuitry for the LF antennas (4 per system) and the
integrated RF receiver (which has been already homologated).
The LF antennas are only necessary to locate the tire position after a tire change.
The antennas are fixed on the steering stub. When the antennas send a 125 kHz
signal to the TPMS transmitter the transponder will be activated and the location
of the tire and the corresponding TPMS transmitter can be read.
The localisation function enables the vehicle driver to get information about which
tire a pressure loss has been detected.

Explanation
5WK4 7594 ECU with integrated receiver 315 MHz
5WK4 7593 ECU with integrated receiver 433.92 MHz
5WK4 7595 LF antenna
The two ECU variants use the same schematic, layout and assembly! The
only difference is the integrated RF receiver (which is not subject to this
homologation).
Typical usage pattern (for Europe only)
Worst case calculation:
4 drive cycles in 24 hours
30 minutes to localise the vehicle
• total transmission duration of 120 minutes in 24 hours
Transmitter ON 5 minutes / hour
Transmitter OFF 55 minutes / hour
Duty Cycle: TON / T (ON+OFF) x 100% = 5 / 60 x 100 % = 8.3%
