OBD-II Code
C0241
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$0–$1,400
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$0 (reflash) to $1,400 (OEM ABS module plus dealer programming).
C0241 means the ABS module is reporting a configuration error — the stored configuration data (VIN, tire size, axle ratio, brake variant, traction-control flag) does not match what the ABS module expects for this vehicle, or the EEPROM where that configuration lives has been corrupted.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

The diagnostic order
- Confirm whether the ABS module was recently replaced, reflashed, or had a battery disconnect — most C0241 cases follow a service event where the as-built configuration did not get rewritten to the new module. The fix is to run the OEM scan tool's variant-coding or configuration-rewrite procedure, which pulls the correct config from the VIN database — $0-$150 at a dealer or capable independent.
- If no recent service touched the ABS, scan for related codes — C0241 alongside C0561 (configuration not set) on GM trucks usually means the module needs programming, not replacement.
- Check power and ground at the ABS module — modules pull 12V constant, 12V switched, and a heavy ground; a marginal ground will let the module power up enough to communicate but fail self-test and report config error. Misdiagnosis caveat: never replace an ABS module on a C0241 before attempting variant coding or reflash — a brand-new module ships uncoded and will throw the same code until it is programmed for the specific VIN; $1,200 part swap followed by 'still broken' is the classic shop mistake on this code.

- 1999-2007GM trucks (Silverado, Sierra, Tahoe, Suburban, Avalanche) with the Kelsey-Hayes 325 EBCM are the most common C0241 ticket in North America — the EBCM is famous for solder-joint failure on the internal driver chips, and bench-rebuild specialists (Module Master, ModuleExperts) will refurbish the original board for $180-$300 and ship it back fully programmed vs. a $1,000-$1,400 OEM replacement that still needs dealer programming.
- 2003-2009Dodge Ram 1500/2500/3500 throws C0241 from CAB (Controller Antilock Brake) connector corrosion at the master cylinder.
- 2007-2013Ford Edge/Lincoln MKX commonly throws C0241 after a battery disconnect because the ABS module lost its stored config and needs an IDS/FORScan rewrite.
- 2008-2014Honda Accord/Pilot throws C0241 after wheel bearing or hub replacement when the new hub's tone-ring count does not match what the ABS module expects (look for aftermarket hubs with the wrong tooth count).
