What does this fault code mean?
The voltage supply to the steering wheel angle sensor control module is registered as faulty. The cause may be poor contact at a connector on the sensor control module or steering wheel module, or an internal fault in the control module.
Possible causes
- Contact resistance or oxidation at a connector on the sensor control module or steering wheel module
- Internal fault in the control module
What you can do
- 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
- 3With diagnostic equipment, read the codes again after the connectors have been checked; if the code does not return, poor contact or oxide was probably the cause
- 4Check the wiring between the control module and the sensor for breaks and chafing; if no fault is found, a workshop may need to replace the sensor
- 5The anti-spin lamp is on, so have a workshop repair the fault promptly if it returns
Symptoms you may notice1
- Anti-spin warning lamp is on
