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

- If within the standard value, check the power supply and the earth circuits.
- If not within the standard value, drain the A/T fluid and remove the valve body cover.
)
- Disconnect the solenoid valve connectors.
)
- 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 )
- If not within the standard value, replace the solenoid valve.
- 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. (Refer to GROUP 23B,C Automatic Transmission Overhaul.)
