A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Speed was above the limit at which cruise works
- Speed sensor or wheels of a different size
What you can do yourself
- The code is stored when driving on cruise faster than its limit. If you didn’t, check the speed sensor.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
