MONITOR DESCRIPTION
After the ignition switch is turned off, the No. 2 skid control ECU (brake actuator assembly) automatically performs a pressure increase check to detect malfunctions that would be difficult to detect during normal braking.
During the current trip when the vehicle is being driven at a certain speed or more and the following sequence is met, the No. 2 skid control ECU (brake actuator assembly) judges that the switching solenoid (SGH) is stuck closed and illuminates the MIL and stores this DTC.
- When the linear solenoid (SLR) is being operated to reduce servo pressure and the switching solenoid (SSA) and switching solenoid (SGH) are both closed, when the output piston is released, the volume of the reaction chamber expands, and because brake fluid is not introduced, a negative pressure is created.
- In the case of 1, if the negative pressure does not change for a certain amount of time, the No. 1 skid control ECU (brake booster with master cylinder assembly) repeatedly opens and closes the switching solenoid (SSA) and switching solenoid (SGH).
-
After 2 is performed, the linear solenoid (SLA) is operated to increase servo pressure and the reaction force pressure rises. When the switching solenoid (SGH) is instructed to be on (open) and there is a stuck closed malfunction, because the reaction force pressure does not reduce, when the reaction pressure exceeds a specific value for a certain amount of time, the No. 2 skid control ECU (brake actuator assembly) judges that there is a malfunction.
