Hva betyr feilkoden?
The steering wheel module (SWM) has detected that communication with the right steering wheel switch (SWSR) is disturbed or missing, and the switch does not respond. The signals travel over LIN communication, so the fault can lie in the switch, in the cable to it or in the steering wheel module. The radio, phone and RTI controls on the wheel stop responding.
Mulige årsaker
- Communication problems, with the right steering wheel switch (SWSR) not responding
Hva du kan gjøre
- 1If you have a diagnostic tool: activate the buttons on the right steering wheel switch and check in live data that the status changes
- 2Switch the ignition off and check the connector and wiring to the right steering wheel switch for loose contacts, corrosion and breaks
- 3Use a multimeter to check that the wiring to the steering wheel switch has no open circuit
- 4If no fault is found, have a workshop replace the steering wheel switch (SWSR)
- 5If the fault remains after replacement, have a workshop check the steering wheel module (SWM)
- 6Reconnect the connectors properly, clear the fault code and check that the buttons work again
