Part 2

Solenoid Valves (Shift Solenoid Valves and TCC Solenoid Valve) Inspection
Resistance Check
Shift solenoid valve-A (No. 1), -B (No.2) and TCC solenoid valve

Shift solenoid valve-A and B resistance
Standard: 11 - 15 ohms at 20°C (68°F)





TCC solenoid valve resistance
Standard: 12 - 16 ohms at 20°C (68°F)

Operation Check





Shift solenoid valve-A (No.1) and -B (No. 2)
^ Check that solenoid valve (1) actuate with click sound when battery voltage is conducted.
^ Apply oiler (2) to solenoid valve (1) and give compression by hands and then check to be sure that transaxle fluid from oiler does not come out of holes in solenoid valve when battery voltage is not conducted.
^ Under the same conditions, conduct battery voltage and then make sure that fluid comes out with vigor. If check result is not as described, replace shift solenoid valve.





TCC solenoid valve
^ Check that solenoid valve (1) actuate with click sound when battery voltage is conducted.
^ Apply oiler (2) to solenoid valve (1) and give compression by hands and then check to be sure that transaxle fluid from oiler does not come out of holes in solenoid valve when battery voltage is conducted.
^ Under the same conditions, release battery voltage and then make sure that fluid comes out with vigor. If check result is not as described, replace shift solenoid valve.

Pressure Control Solenoid Valve Inspection
Resistance Check
Check resistance between pressure control solenoid valve (1) terminals. If check result is not as specified, replace solenoid valve.





Pressure control solenoid valve resistance
Standard: 5.0 - 5.6 ohms (at 20°C (68°F))

Operation Check
Check pressure control solenoid valve operation in the either manner of the following.

Using regulated DC power supply
1. Connect pressure control solenoid valve (1) with regulated DC power supply (2) as shown in the figure.
2. Turn regulated DC power supply switch ON and increase voltage of power supply keeping current within 1.0 A.
3. Check for gradual movement of valve (3) in the direction of arrow "A" as voltage is increased.
4. Check movement of valve (3) in the direction of arrow "B" as voltage is decreased.
5. Turn power supply switch OFF.





CAUTION: Do not pass current 1.0 A or more, or pressure control solenoid is burned out.

Not using regulated DC power supply
1. Connect pressure control solenoid valve (1) to battery (2) setting the 8 - 10 W bulb (4) on the way as shown in the figure.
2. Check for movement of valve (3) in the direction of arrow "A".





3. Disconnect pressure control solenoid valve (1) from battery (2) and check movement of valve (3) in the direction of arrow "B" as shown in the figure.

CAUTION: Set 8 - 10 W bulb on the way, or pressure control solenoid valve is burned out.
