DTC C1211: SLA Linear Solenoid; DTC C1212: SLR Linear Solenoid; DTC C1225: SA1 Solenoid Circuit; DTC C1226: SA2 Solenoid Circuit [01/2019 - 09/2022]: Description
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 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.
- DTC C1225 indicates a malfunction related to solenoid SSA, and DTC C1226 indicates a malfunction related to solenoid SGH.
