The system closes the cut valve to shut the fluid channel from the master cylinder to
the wheel cylinders, and opens the suction valve to open the fluid channel from the
master cylinder to the hydraulic unit reservoir. The brake fluid, which is pumped
from the master cylinder to the hydraulic unit reservoir, is supplied to the wheel
cylinders.
NOTE: At this time, the hydraulic unit reservoir cannot operate due
to the fluid pressure from the master cylinder.
NOTE: *: When the ASC is operating while the brake pedal is
depressed, the suction valve turns on and off according to
the brake fluid amount supplied to the buffer chamber.

The system closes the inlet solenoid and opens the outlet solenoid. This causes the
brake fluid in the wheel cylinders to return to the buffer chamber, and decreases the
fluid pressure in the wheel cylinders. If the returned brake fluid pressure exceeds a
predetermined pressure, excessive brake fluid is returned to the master cylinder.

CIRCUIT OPERATION
CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set.
Diagnose the CAN bus lines before the DTC (Refer to
DIAGNOSTIC TROUBLE CODE DIAGNOSIS
).

CIRCUIT OPERATION
The TCL/ASC-ECU contains the power supply circuit (terminal 11) for the
solenoid valve. The solenoid valve is energized by the valve relay, which i
incorporated in the TCL/ASC-ECU. The valve relay, which is incorporated in the TCL/ASC-ECU, is always
energizing the solenoid valve unless the initial check is in progress when the
ignition switch is turned on. The TCL/ASC-ECU activates the solenoid valve by turning on its driving
transistor.
TCL/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the power supply circuit to
the TCL/ASC-ECU solenoid valve, or the valve relay has failed). The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the solenoid valve circuit
inside the TCL/ASC-ECU, or the valve relay has failed). After the TCL/ASC-ECU has turned off the driving transistor, the solenoid
valve still remains energized (short in the solenoid valve circuit). When a solenoid valve failure is detected

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1266, C1273 or C1274 set?
YES: Go to Step 1.
NO: The procedure is complete.
