2. Disconnect the connectors from the solenoid valves B and C for regulating the pressure in the automatic transmission clutches.
3. Measure the resistance of the solenoid valves B and C for regulating the pressure in the automatic transmission clutches at the connectors of the solenoid valves B and C, respectively.
Standard: about 5 Ohm
4. If the resistance of any of the valves differs from the norm, replace the solenoid valves B and C for regulating the pressure in the automatic transmission clutches.
5. Connect the cable from the positive battery terminal to contact No. 1 of the connectors of the solenoid valves B and C 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 valves B and C for regulating the pressure in the automatic transmission clutches.
7. Check if there is any dust or dirt in the channel of the solenoid valves regulating the pressure in the automatic transmission clutches.
8. Connect the cable from the positive battery terminal to terminal No. 1 of the connectors of the solenoid valves B and C for regulating the pressure in the automatic transmission clutches, and the cable from the negative battery terminal to terminal No. 2. Make sure that the solenoid valves B and C for regulating the pressure in the automatic transmission clutches move.
9. Disconnect one of the cables from the battery and check if the valves move.
Note: You can observe the valve movement through the fluid channel on the mounting surface of the housing of the solenoid valves B and C for regulating the pressure in the automatic transmission clutches.
10. If any of the valves stick, move slowly or do not operate, replace the A/C clutch pressure control solenoid valves B and C.
