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 system regenerative braking force and inputs the fluid pressure necessary for operating each wheel cylinder according to the wheel cylinder pressure sensor.
DTCs may be stored if brake fluid leaks, wheel cylinder vibrates due to uneven wear of the brake disc rotor, or foreign matter enters the solenoid valve.
DTCs may be stored if the line pressure drops during air bleeding.
