Frequently Asked Questions

Is it safe to drive with error code C0561?
You can drive short distances at reduced speeds to reach a repair facility, but your ABS system is disabled. Avoid hard braking and maintain extra following distance as your wheels may lock up during emergency stops.
What causes ABS error code C0561?
Common causes include faulty wheel speed sensors, damaged wiring, blown ABS fuse, corroded electrical connections, or internal ABS module failure. The code typically appears when another ABS-related fault disables the entire system.
Can I clear C0561 myself?
Yes, you can clear the code with an OBD-II scanner, but it will likely return if the underlying problem isn't fixed. Clearing codes is only a temporary solution and should be followed by proper diagnosis and repair.
How much does it cost to fix C0561?
Costs vary widely depending on the cause. A blown fuse costs under $5, wheel speed sensor replacement ranges from $100-300 per sensor, while ABS module replacement or repair can cost $500-1500 including labor.
Will C0561 cause my car to fail inspection?
Yes, in most states, a disabled ABS system with active warning lights will cause your vehicle to fail safety inspection. The system must be repaired and functioning properly to pass.
