DTC C1211/25: SLA Linear Solenoid; DTC C1212/26: SLR Linear Solenoid; DTC C1225/31: SA1 Solenoid Circuit; DTC C1226/32: SA2 Solenoid Circuit; DTC C1227/33: SA3 Solenoid Circuit; DTC C1228/34: STR Solenoid Circuit; DTC C1352/21: FR Solenoid; DTC C1353/23: RR Solenoid; DTC C1356/22: FL Solenoid; DTC C1357/24: RL Solenoid [08/2013 - ]: Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
Each solenoid adjusts pressure which affects each wheel cylinder according to signals from the skid control ECU (brake booster with master cylinder assembly) and controls the vehicle.
The master cut solenoid is closed and blocks the regulator 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 and regulator hydraulic pressure to the non-assisted brake wheel cylinders during fail-safe operation during a system malfunction.
HINT:
If the supply voltage decreases, a drop in current may cause a DTC to be stored.
