DTC C139A-00: Brake Pressure Control solenoid Circuit Malfunction; DTC C13D9-00: Brake Pressure Too Low (Brake Booster); DTC C14EC-7E: Brake Pressure Control solenoid "C" Actuator Stuck On [11/2021 - 10/2023]: Description
The No. 1 skid control ECU (brake booster with master cylinder assembly) controls the brake fluid pressure of the master cylinder based on the output of the brake fluid pressure sensor.
DTCs may be stored if one of the following occurs:
- Brake fluid leaks.
- Foreign matter enters a solenoid valve.
- Line pressure drops during air bleeding.
- Brake pads are replaced.
- Rotors are replaced.
