Inspection of Operation

Note

•

When inspecting the pressure control solenoid, connect the GND connection to the GND terminal (I 
terminal) of the pressure control solenoid inside the solenoid valve connector.

•

Do not apply voltage for more than 3 seconds.

1. Apply B+ to terminal A, B, C, F, or G and battery 

negative voltage to GND, and verify that a click 
sound is heard from each solenoid.

•

If the click sound is not heard from each 
solenoid, replace solenoids.

2. Apply B+ to terminal D and battery negative 

voltage to terminal I, and verify that a click sound 
is heard from solenoid.

•

If the “click” is not heard, replace the solenoid 
valve. (See 05–17–30 SOLENOID VALVES 
REMOVAL/INSTALLATION.)

Resistance Inspection (Off-vehicle)

1. Measure the resistance of each solenoid valve individually.

•

If not as specified, replace the solenoid valve.

Pressure control solenoid

Resistance: 2.4—7.3 ohms

SOLENOID VALVES REMOVAL/INSTALLATION

A3U051721280W02

1. Remove the control valve body. (See 05–17–36 On-vehicle Removal.)
2. Remove the solenoid valve(s).
3. Apply ATF to a new O-ring and install it on the 

solenoid valve.

4. Install the solenoid valve in the control valve 

body.

Tightening torque

7.9—10.7 N·m {80—110 kgf·cm, 69.5—95.4 

in·lbf}

5. Install the control valve body. (See 05–17–38 On-

vehicle Installation.)

6. Add in ATF and, with the engine idling, inspect 

the ATF level and inspect for leakage. (See 05–
17–18 AUTOMATIC TRANSAXLE FLUID (ATF) 
REPLACEMENT.) (See 05–17–18 Automatic 
Transaxle Fluid (ATF) Level Inspection.)

7. Carry out the mechanical system test. (See 05–

17–11 MECHANICAL SYSTEM TEST.)

8. Carry out the road test. (See 05–17–14 ROAD 

TEST.)

O/D OFF INDICATOR LIGHT INSPECTION

A3U051755480W01

Inspection of Operation

1. Turn the IG SW from OFF to ON.

Note

•

The O/D OFF indicator light flashes when any malfunction exists in the EC-AT system components.

2. Verify that the O/D OFF indicator light is not illuminating.
3. Depress the switch and verify that the O/D OFF indicator light illuminates.

•

If the O/D OFF switch does not function, inspect the O/D OFF switch, and then inspect the terminal voltage 
of the O/D OFF indicator light.
