C0024Brake Pedal Feedback Pressure Solenoid Circuit
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- 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.
