What it means
This code has no generic meaning assigned by SAE J2012 or ISO 15031-6. Any description for it is manufacturer-specific.
How it works
C0241 is manufacturer-specific, and its title does not establish which valve or circuit the vehicle monitors. If the vehicle-specific definition identifies an electronic brake control module control-valve circuit, the module checks that circuit's electrical response and sets the code when it falls outside its expected operation; confirm the valve and fault type before testing.
Common causes
Most likely first.
- Manufacturer-specific diagnostic definition
- Vehicle-specific scan-tool decoding
Symptoms
- Symptoms depend on the vehicle-specific meaning
How to diagnose it
- Read the brake control module with a compatible scan tool and confirm the exact vehicle-specific description and any accompanying codes.
- Check freeze-frame or event data and note whether the fault is current or stored, along with any valve command or status data available.
- Inspect the identified control-valve connector and harness for corrosion, loose pins, fluid intrusion, or physical damage.
- Check relevant fuses, power, and ground using the vehicle-specific wiring diagram.
- Test the identified valve circuit and valve response according to the manufacturer's procedure and specification before considering module diagnosis.
Common fixes
- Secure or clean the control-valve connector if the contacts are dirty or loose.
- Repair damaged wiring or restore a poor power or ground connection.
- Replace a failed control valve if circuit testing confirms the fault is within the valve.
- Repair or replace the brake control module only if the manufacturer’s diagnostic procedure confirms it is faulty.
Can I keep driving?
The code may mean ABS or other brake-control functions are limited, depending on the vehicle. Drive cautiously and avoid hard braking or slippery conditions; if the brake warning light is on or pedal feel changes, stop safely and have the system checked.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
