Co oznacza ten kod błędu?
The brake control module (BCM) has found that the rolling circumference differs too much between the wheels. This suggests that one wheel or tyre has the wrong size, or that one or more tyres are unevenly worn. The indirect tyre pressure monitoring cannot rely on its calculations and is switched off.
Możliwe przyczyny
- A wheel of the wrong size has been fitted to the car
- One or more of the car's tyres are too worn
Co możesz zrobić
- 1Check that all four wheels are the same size and that no spare wheel or winter tyre is a different size
- 2Check the tyre wear, and that the tyres on the same axle are of the same type and wear
- 3Check the air pressure in all tyres
- 4Do not replace the brake control module, as it is normally not the fault. Once the fault is fixed, drive the car for a while so the system can recalibrate
- 5The brakes work, but drive carefully until the fault is fixed as the assistance systems may be disabled
Objawy, które możesz zauważyć2
- Tyre pressure monitoring shows a fault or no indication
- Yellow warning symbol and message in the display
Na co może wpływać usterka1
- Indirect tyre pressure monitoring (iTPMS) is switched off
