DTC C13DB-00: Brake Pressure Too Low (Brake M/C1); DTC C13DD-00: Brake Pressure Too Low (Brake M/C2) [11/2020 - ]: Description
The No. 2 skid control ECU (brake actuator assembly) controls the brake fluid pressure of each wheel cylinder based on the brake fluid pressure sensor.
DTCs may be stored if one of the following occurs:
- Brake fluid leaks.
- Wheel cylinder vibrates due to uneven wear of a brake disc.
- Foreign matter enters a solenoid valve.
- Line pressure drops during air bleeding.
- Brake pads are replaced.
- Rotors are replaced.
HINT:
When replacing the brake pads, retracting the brake caliper pistons and installing new brake pads will greatly increase the clearance between the brake pads and brake discs. This will result in a significant possibility of this DTC being stored the next time the brake pedal is depressed. As this is not a malfunction, clear the DTC if it is stored for this reason.
