DESCRIPTION AND OPERATION 86-10-13

 Tyre Sensor Assembly

1 Sensor body
2 Torx bolt

3 Filter
4 Inflation valve

TPM Antenna
A TPM antenna is installed inside each wheel arch, behind the wheelarch liners. 'Twisted pair' wires connect each 
TPM antenna to the TPM ECU.

TPM ECU
The TPM ECU is installed below the front passenger seat, in a mounting bracket together with the Body Control Unit 
(BCU) and the security system tilt sensor. The TPM ECU incorporates a Radio Frequency (RF) receiver, to decode 
the radio signals from the antennas, and system electronics for control and diagnostics.

One of two software versions is incorporated in the TPM ECU, depending on market:

l

Software version 9 is incorporated in all markets except NAS

l

Software version 10 is incorporated in NAS markets.

Power for system operation is provided by a permanent power feed and an ignition switched power feed from fuses 
in the passenger compartment fusebox. On a K bus connection with the instrument pack, the TPM ECU can:

l

Communicate with the diagnostic socket

l

Receive road speed and ambient temperature data from the instrument pack

l

Send caution and warning messages to the instrument pack.

A hardwired connection with the BCU allows the TPM ECU to trigger the vehicle alarm if it detects rapid deflation of 
a tyre while the vehicle is parked.
