In the event of a fault in the circuit and/or wiring harness leading to the ECU, or in the event of a TPMS ECU
fault, or in the event of no signal reception from one or more sensors due to fault, breakage or flat battery,
the TFT display displays the specific message "TPMS failure".
The vehicle symbol is not displayed. Therefore, if the fault occurs while the TYRES screen is active, the
default screen is shown automatically.
Simultaneously, the specific indicator light starts flashing and continues to flash for a maximum period of 90
seconds (determined by NTP), after which the indicator light remains lit continuously until normal
operating conditions are restored.
The TYRES screen is not recallable by the driver.
- Punctured tyre
When the instrument panel receives the signal from the electronic control unit indicating that the pressure of
one or more normal tyres is below the alarm threshold, but the system cannot recognise which wheel is
generating the failure signal, the TFT display displays the specific message "Low tyre pressure" together
with the message "Do not proceed" in area B2 of the screen, without the vehicle symbol.
If the vehicle is driven for more than 100 Km (62 mi) in "punctured tyre" state, the specific screen is displayed.
