SOLENOID VALVE CHECK


1.Use the M.U.T.-III to measure the A/T fluid temperature and check that the A/T fluid temperature is 20°C.

2.Disconnect the A/T control solenoid valve assembly connector.
3.Measure the resistance between the solenoid valve terminals.
4.Check that the measured values are within the standard values at items 1 and 3.

STANDARD VALUE:
Name
 Terminal No.
 Resistance value
Damper clutch control solenoid valve
 7 - 10
 2.7 - 3.4 Ω (A/T fluid temperature 20°C)
Low-reverse solenoid valve
 6 - 10
Second solenoid valve
 4 - 9
Underdrive solenoid valve
 3 - 9
Overdrive solenoid valve
 5 - 9
5.If within the standard value, check the power supply and the earth circuits.
6.If not within the standard value, drain the A/T fluid and remove the valve body cover.

7.Disconnect the solenoid valve connectors.

8.Measure the resistance between terminals 1 and 2 at each solenoid valve side.
Standard value: 2.7 - 3.4 Ω (A/T fluid temperature 20°C)
9.If not within the standard value, replace the solenoid valve.
10.If within the standard value, check the harness wire between A/T control solenoid valve assembly connector and each solenoid valve connector. If a problem is not found at the steps above, check the solenoid valve O-rings and replace if necessary.
