2. Disconnect the connector from the solenoid valve A for regulating the pressure in the automatic transmission clutches.
3. Measure the resistance of the solenoid valve A for regulating the pressure in the automatic transmission clutches at the solenoid valve A connector.
Standard: about 5 Ohm
4. If the resistance differs from the norm, replace the solenoid valve A for regulating the pressure in the automatic transmission clutches.
5. Connect the cable from the positive battery terminal to contact No. 1 of the connector of the solenoid valve A for regulating the pressure in the automatic transmission clutches, and the cable from the negative battery terminal to contact No. 2. A clicking sound should be heard.
6. If the sound is not heard, remove the solenoid valve A for regulating the pressure in the automatic transmission clutches.
7. Check if there is any dust or dirt in the channel of the solenoid valve A for regulating the pressure in the automatic transmission clutches.
6. Connect the cable from the positive battery terminal to terminal No. 1 of the automatic transmission clutch pressure control solenoid valve A connector, and the cable from the negative battery terminal to terminal No. 2. Make sure that automatic transmission clutch pressure control solenoid valve A moves.
9. Disconnect one of the cables from the battery and check if the valve moves.
Note: You can observe the valve movement through the fluid channel on the mounting surface of the A/C clutch pressure control solenoid valve A housing.
10. If the valve sticks, moves slowly or does not work, replace the A/C clutch pressure control solenoid valve A.
