Hva betyr feilkoden?

The CEM supplies the steering wheel heater control module (HSWM) through a relay. The steering wheel control module (SWM) measures the temperature in the wheel and sends a diagnostic signal to the CEM when it detects a fault in the steering wheel heating system, and the fault code is then set. The fault may lie in the HSWM, in the steering wheel control module, in the wiring between them, or in the heating element in the rim.

Mulige årsaker

Internal fault in the steering wheel heater control module (HSWM)
No power supply to the steering wheel heater control module (HSWM)
Internal fault in the steering wheel control module (SWM)
Fault on the private LIN bus between the steering wheel control module and the steering wheel heater control module
The heating element in the rim is short-circuited or open
The signal wire to the temperature sensor in the rim is short-circuited or open

Hva du kan gjøre

1If you have a diagnostic tool, read the freeze frame data of the fault code and note which fault is indicated
2Check the fuse for the steering wheel heater and that the relay supplies the steering wheel heater control module
3Check the wiring between the steering wheel control module and the steering wheel heater control module for breaks, chafing and loose connectors
4With the connectors disconnected, use a multimeter to check that the heating element wires are intact and not short-circuited
5If no fault is found, have a workshop check the steering wheel control module and the heater control module, as one of them will probably need replacing

Symptomer du kan merke1

The steering wheel heater does not work

Hva feilen kan påvirke2

The steering wheel heater switches off for the rest of the current driving cycle
After several driving cycles with a detected fault, the steering wheel heater is switched off permanently until the fault code has been remedied
