What does this fault code mean?
The battery voltage is too low and the fault is present right now. The ABS control module cannot work with sufficient voltage, so ABS, traction control and stability control are blocked. The cause often lies in the battery, the charging or the connectors to the module.
Possible causes
- Contact resistance in the connections
- Faulty alternator
- Disturbances on the wires
