DTC C1341/62: Front Hydraulic System RH Malfunction; DTC C1342/63: Front Hydraulic System LH Malfunction; DTC C1343/64: Rear Hydraulic System RH Malfunction; DTC C1344/65: Rear Hydraulic System LH Malfunction: Description
The skid control ECU controls braking force according to the hybrid control system regenerative braking force and inputs the hydraulic pressure necessary for operating each wheel cylinder according to the wheel cylinder pressure sensor.
DTCs may be stored if one of the following occurs:
- Brake fluid leaks.
- A wheel cylinder vibrates due to uneven wear of a brake rotor.
- Foreign matter enters a solenoid valve.
- The line pressure drops during air bleeding.
- A brake pad is replaced.
- A rotor is replaced.
HINT:
When replacing the brake pad, retracting the brake caliper's piston and attaching a new brake pad will greatly increase the clearance between the brake pad and brake disc, which will likely cause these DTCs to be set the next time the brake pedal is depressed. As this is not malfunction, clear the DTCs.
