DTC C1315/31: SMC1 Changeover Solenoid Malfunction; DTC C1316/32: SMC2 Changeover Solenoid Malfunction; DTC C1352/21: Front Increasing Pressure Solenoid RH Malfunction; DTC C1353/23: Front Increasing Pressure Solenoid LH Malfunction; DTC C1354/25: Rear Increasing Pressure Solenoid RH Malfunction; DTC C1355/27: Rear Increasing Pressure Solenoid LH Malfunction; DTC C1356/22: Front Decreasing Pressure Solenoid RH Malfunction; DTC C1357/24: Front Decreasing Pressure Solenoid LH Malfunction; DTC C1358/26: Rear Decreasing Pressure Solenoid RH Malfunction; DTC C1359/28: Rear Decreasing Pressure Solenoid LH Malfunction: Description
Each solenoid adjusts the pressure which affects each wheel cylinder according to signals from the skid control ECU and controls the vehicle.
The master cut solenoid (SMC1/2) is closed and blocks the master cylinder pressure from the electronically controlled brake system control pressure when the system is normal. The master cut solenoid is open and sends the master cylinder hydraulic pressure to the non-assisted brake wheel cylinders while the fail-safe operates due to a system malfunction.
