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
- The ECU expects a rough-road signal (usually from ABS) but doesn’t get it
- ECU from a different trim level
What you can do yourself
- Often appears after replacing the engine ECU or ABS unit. Check that the unit matches the car.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
