Hva betyr feilkoden?
The upper electronic module (UEM) should receive signals from all four approved tyre pressure sensors. The code is set when it gets a signal from fewer than four of them during any driving cycle. The cause can be a wheel without a sensor, a sensor not intended for the car, a faulty sensor, or a receiver that is not working.
Mulige årsaker
- A rim without a tyre pressure sensor has been fitted
- A rim carrying a sensor meant for another model has been fitted, so the sensor cannot talk to the receiver
- Defective tyre pressure sensor
- The receiver is not working
Hva du kan gjøre
- 1Check that the receiver works: press the lock and unlock button on the remote control and see that the car locks and unlocks.
- 2Check that every rim has a tyre pressure sensor fitted. If a sensor is missing or does not suit the car, have a workshop fit the correct one.
- 3Have a workshop activate the sensors with diagnostic equipment and check that each wheel shows its own ID number.
- 4Clear the code and check whether it comes back.
- 5If the fault remains, have a workshop replace the tyre pressure sensor that does not respond.
