A/T Clutch Pressure Control Solenoid Valve B and C Test

A/T Clutch Pressure Control Solenoid Valve B and C Test





1. Connect the HDS to the DLC (A).
2. Choose Clutch Pressure Control (Linear) Solenoid B and C in Miscellaneous Test Menu on the HDS.
3. Test the A/T clutch pressure control solenoid valve B and C with the HDS.
4. Follow instructions indicated on the HDS by the test result. If the HDS has not determined the cause of the failure, remove A/T clutch pressure control solenoid valve B, C, and test.





5. Disconnect the A/T clutch pressure control solenoid valves B and C connectors.
6. Measure A/T clutch pressure control solenoid valve B resistance between the solenoid valve B terminals No. 1 and No. 2, and measure A/T clutch pressure control solenoid valve C resistance between the solenoid valve C terminals No. 1 and No. 2.
Standard: 3 - 10 Ohms
7. If the resistance of either A/T clutch pressure control solenoid valve is out of standard, replace A/T clutch pressure control solenoid valves B and C.
8. If the resistance is within the standard, connect the battery positive terminal to the No. 1 terminal of the A/T clutch pressure control solenoid valves B and C connectors, and connect the battery negative terminal to the No. 2 terminal. A clicking sound should be heard.
9. If no sound is heard, remove the A/T clutch pressure control solenoid valves B and C.
10. Check the fluid passage of the A/T clutch pressure control solenoid valve for dust or dirt.





11. Connect the No. 1 terminal of the A/T clutch pressure control solenoid valves B and C connectors to the battery positive terminal, and connect the No. 2 terminal to the battery negative terminal. Make sure the A/T clutch pressure control solenoid valves B and C move.
12. Disconnect one of the battery terminals, and check valve movement.

NOTE: You can see valve movement through the fluid passage in the mounting surface of the A/T clutch pressure control solenoid valves B and C body.

13. If either valve binds or moves sluggishly, or if the solenoid valve does not operate, replace the A/T clutch pressure control solenoid valves B and C.
