What does this fault code mean?
The ABS control module registered an incorrect signal from within itself on an earlier occasion, but has since confirmed that the fault is no longer present. The fault is intermittent, meaning temporary. The cause may be interference that affected the module's calculations, but a genuine internal fault can also be behind it.
Possible causes
- Interference or noise that has affected the control module's calculations
- Faulty ABS control module
