Co oznacza ten kod błędu?
The sensor control module registers that the signal from the sensor is faulty. The cause may be poor contact at a connector, faults in the signal cables, or an internal fault in the sensor or its control module.
Możliwe przyczyny
- Contact resistance or oxidation at a connector in the sensor control module or steering wheel module
- Signal cable fault between the sensor and its control module
- Internal fault in the sensor
- Internal fault in the control module
Co możesz zrobić
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connectors at the sensor control module and the steering wheel module are firmly seated and free from oxide
- 3If the fault disappears once the connectors have been cleaned and reseated, poor contact was probably the cause
- 4With a multimeter, check that the signal wires are not short-circuited to ground or to supply voltage
- 5The anti-spin lamp is on, so have a workshop repair the fault promptly if it returns
Objawy, które możesz zauważyć2
- Anti-spin warning lamp lit
- Stability function absent
