2. HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of the oil pump, the valve body, the solenoid valves, the accu-
mulators, the clutches and brakes, and the governor valve as well as the fluid passages which connect
all of these components.
Based on the hydraulic pressure created by the oil pump, the hydraulic control system governs the hy-
draulic pressure acting on the torque converter clutch, clutches and brakes in accordance with the ve-
hicle driving conditions.
There are three solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to operate the shift
valves and change the gear shift position.
The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lock±up
clutch of the torque converter.

of the torque converter clutch.
The SLN solenoid valve is operated by signals from the ECM to control the engagement speed and
reduce gear shift shock.

ISTOR OPERATION
(a) Disconnect the connector from the power window switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 1 on the wire harness side connector and the negative
(±) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
2 on the wire harness side connector, and raise the win-
dow to the fully position.
(d) Continue to apply voltage and check that the current
changes to less than 1 A within 4 to 90 seconds.
(e) Disconnect the leads from the terminals.
(f) Approximately 60 seconds later, connect the positive (+)
lead from the battery to terminal 2 and the negative (±)
lead to terminal 1, and check that the window begins to
descend.

window signal.
(a) Connect the positive (+) lead from the voltmeter to termi-
nal A3 and the negative (±) lead to body ground.
(b) Close the door with ignition switch turned to LOCK or
ACC, and check that the meter needle indicates battery
positive voltage.
(c) Open the door and check that the meter needle indicates
0 V.
