Signs You May Need Regenerative Braking Service
- One of the most common brake problems in the Toyota Prius (2010-2015) is brake actuator failure. The actuator is responsible for maintaining brake pressure and ensuring smooth operation. When it fails, you may experience:
- Brake Warning Lights – ABS, Brake, and Traction Control lights turning on.
- Unusual Noises – Clicking or buzzing sounds from under the hood.
- Spongy or Unresponsive Brake Pedal – Delayed braking response.
- Causes:
- Internal component wear over time.
- Hydraulic pressure loss due to a faulty pump
- 1. C1256 – Accumulator Low Pressure Malfunction
- This code indicates that the brake actuator assembly is experiencing low accumulator pressure, which can compromise braking performance.
- 2. C1391 – Abnormal Leak of Accumulator Pressure
- This code signifies an abnormal drop in brake accumulator pressure, often due to internal fluid leaks within the brake actuator assembly.
- 3. C1252 – Brake Booster Pump Motor On Time Abnormally Long
- This code indicates that the brake booster pump motor is running longer than expected, suggesting potential issues with maintaining brake pressure.
- If your Prius displays any of these codes, it’s crucial to have the braking system inspected and repaired promptly to maintain vehicle safety and performance.
