DESCRIPTION
The solenoid comes on when signals are received from the ECU and controls the pressure acting on the wheel cylinders, thus controlling brake force.

INSPECTION PROCEDURE
1 RECONFIRM DTC
HINT: These codes are detected when a problem is identified in the brake actuator.
The solenoid circuit is in the brake actuator.
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTC is output before replacing the brake actuator assembly.
(a) Clear the DTCs (See page BC-10).
(b) Start the engine.
(c) Drive the vehicle at the speed of 4 mph (6 km/h) or more.
(d) Check that the same DTCs are recorded (See page BC- 10).
HINT: If a speed signal of 4 mph (6 km/h) or more is input to the skid control ECU, with the ignition switch on and the stop light switch off, the ECU performs self-diagnosis of the motor and solenoid circuits.

Diagnostic trouble code chart
HINT:
The parameters listed in the chart may not confirm exactly to
those read during the DTC check due to the type of
instrument or other factors.
If a trouble code is displayed during the DTC check in the
check mode, check the circuit for the code listed in the table
below. For details of ...
Intake Air Temperature Sensor Gradient Too High
DESCRIPTION
The Intake Air Temperature (IAT) sensor, mounted on the Mass Air Flow (MAF)
meter, monitors the IAT.
The IAT sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the IAT becomes low, the resistance of the the ...
Checking monitor status
The purpose of the monitor result (mode 06) is to allow
access to the results for on-board diagnostic monitoring tests
of specific components/systems that are not continuously
monitored. Examples are catalyst, evaporative emission
(EVAP) and thermostat.
The monitor result allows the OBD II sc ...
