C0024 code meaning
Brake Pedal Feedback Pressure Solenoid Circuit
What C0024 means
Covers the solenoid that generates brake pedal feedback pressure in an electronic or brake-by-wire braking system. Because the driver is hydraulically decoupled during controlled braking, a pedal-feel simulator uses this solenoid to build a controlled counter-pressure so the pedal feels natural. The module monitors the coil circuit for opens, shorts and out-of-range resistance and checks that feedback pressure tracks the command. GM documents C0024 on 2019-2020 Cadillac XT6, Chevrolet Blazer and GMC Acadia with reduced brake assist, warning messages in the driver display and an altered pedal feel. A fault alters pedal feel and may reduce controlled assist; the brake or ABS warning lamp is set.
C0024 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0024
- Changed or abnormal pedal feel
- Loss of brake assist, driver messages
- ABS or brake warning lamp on
Common causes of C0024
- Most likelyFeedback solenoid open or shorted
- PossibleHarness or connector fault
- Less likelyInternal brake actuation unit fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C0024 means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 24 | The exact fault in that area. |
What to do next
- Note C0024 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 C0024
What does C0024 mean?
C0024 means "Brake Pedal Feedback Pressure Solenoid Circuit". Covers the solenoid that generates brake pedal feedback pressure in an electronic or brake-by-wire braking system. It is a generic code, so it means the same on every make.
Is it safe to drive with C0024?
Drive gently and only to a workshop. With C0024 the car can go into limp mode (reduced power) to protect itself.
Will C0024 fail an emissions test?
C0024 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 C0024 to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 4 hours of work. This is a job for a workshop.
Will C0024 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
