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 inputs the operating fluid pressure of each wheel cylinder using the wheel cylinder pressure sensors in order to control the braking force of each wheel.
DTCs may be stored if brake fluid leaks, a 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 or brake pad is replaced.
