C0563 code meaning
ABS Control Module Performance
What C0563 means
C0563 is a summary code: the ABS control module reports that it cannot carry out its own function correctly, without pinning the fault on one sensor or valve. Ford shows how it is used. In its 2015–2019 hybrids the ABS module stores internal faults as U3000 (control module) or U2200 (corrupt data), and the hybrid powertrain module mirrors both as C0563 so that regenerative braking faults appear in the OBD system. On 2025–26 F-150, Ranger, Bronco, Expedition and Navigator C0563 sits in the ABS module alongside the message Check Brake System, traced to air left in the system after bleeding or to brake service mode still active; the workshop manual test was revised (SSM 54733). Clear underlying faults first, then check software.

- Clears after repairWhen cleared with a scanner
Symptoms of C0563
- Check Brake System message and ABS lamp
- ABS and stability control unavailable
- Regenerative braking limited on hybrids
Common causes of C0563
- Most likelyAir in the hydraulic system or brake service mode left active after work
- PossibleInternal ABS module fault or corrupted memory
- PossibleOutdated or incomplete module software or configuration
- Less likelyUnstable supply or ground at the ABS module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 63 | The exact fault in that area. |
What to do next
- Note C0563 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0563
What does C0563 mean?
C0563 means "ABS Control Module Performance". C0563 is a summary code: the ABS control module reports that it cannot carry out its own function correctly, without pinning the fault on one sensor or valve. It is a generic code, so it means the same on every make.
Is it safe to drive with C0563?
Drive gently and only to a workshop. With C0563 the car can go into limp mode (reduced power) to protect itself.
Will C0563 fail an emissions test?
C0563 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0563 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will C0563 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
