WARNING: This page is about a different variant/trim than selected.
The linear solenoids SLA and SLR control the regulator based on signals from the No. 1 skid control ECU (brake booster with master cylinder assembly) and produce servo pressure in accordance with the vehicle condition.
When the system is normal, the switching solenoid SGH is opened to allow brake fluid to flow to the stroke simulator when the brake pedal is depressed. When the system is abnormal, the switching solenoid SGH closes to prevent the flow of brake fluid.
When the system is normal, the switching solenoid SSA is closed. When the system is abnormal, the switching solenoid SSA is opened to allow fluid to flow to the brake master cylinder reservoir assembly.
HINT:
- If the supply voltage decreases, a drop in current may cause DTCs to be stored.
- Brake pressure control solenoid "C": Solenoid SLA.
- Brake pressure control solenoid "D": Solenoid SLR.
- Brake pressure control solenoid "E": Solenoid SSA.
- Brake pressure control solenoid "F": Solenoid SGH.
