C0567 code meaning
Brake Booster Solenoid Circuit Low
What C0567 means
C0567 flags the brake booster solenoid circuit as too low – typically a short to ground on the line between the module's high-side driver and the coil. Ford describes the check in its 2015–2019 hybrid summaries: with both high-side and low-side drivers switched off, the module measures the voltage on the solenoid supply; below 3.0 V for 380 ms the fault is stored, and Ford's hybrid powertrain module shows it as C0567 (ABS module code C0022). Because a grounded line can overload the driver, the module stops using the solenoid. Brake assist from the booster then fails and hybrids lose part of the blended braking. Look for chafed harness near the booster or water in the connector before replacing the booster.
C0567 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0567
- Brake system warning lamp
- No automatic brake assist
- Less regenerative braking on hybrids
Common causes of C0567
- Most likelyChafed solenoid wire shorting to body ground
- PossibleMoisture or corrosion bridging the connector pins
- Less likelyShorted solenoid winding inside the booster
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0567 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 C0567
What does C0567 mean?
C0567 means "Brake Booster Solenoid Circuit Low". C0567 flags the brake booster solenoid circuit as too low – typically a short to ground on the line between the module's high-side driver and the coil. It is a generic code, so it means the same on every make.
Is it safe to drive with C0567?
Drive gently and only to a workshop. With C0567 the car can go into limp mode (reduced power) to protect itself.
Will C0567 fail an emissions test?
C0567 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 C0567 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will C0567 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
