Shift Solenoid Valve Test
Shift Solenoid Valve Test1. Connect the HDS to the DLC (A).
2. Choose Shift Solenoid A, B, C, and D Test in Miscellaneous Test Menu on the HDS.
NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.
3. Check that the shift solenoid valves, A, B, C, and D operate with the HDS. A clicking sound should be heard.
^ If a clicking sound is heard, the valves are OK. The test is complete, disconnect the HDS.
^ If no clicking sound is heard, go to step 4, and test the solenoid valves.
4. Lift the vehicle up on a hoist or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
5. Remove the splash shield.
6. Disconnect the shift solenoid harness connector.
7. Measure shift solenoid valve resistance between the shift solenoid harness connector terminals below and body ground:
^ No. 1: shift solenoid valve C
^ No. 2: shift solenoid valve B
^ No. 5: shift solenoid valve A
^ No. 8: shift solenoid valve D
Standard: 12 - 25 Ohms
^ If the resistance is within the standard, go to step 8 and check solenoid valve for a clicking sound.
^ If the resistance is out of standard, go to step 9.
8. Connect a jumper wire from the battery positive terminal to each shift solenoid harness connector terminals individually. A clicking sound should be heard.
^ If a clicking sound is heard, the valves are OK. The test is complete, connect the connector.
^ If no clicking sound is heard, go to step 9 and test the shift solenoid harness.
9. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
10. Reinstall the drain plug with a new sealing washer (B).
11. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
12. Disconnect the connectors from shift solenoid valve A, shift solenoid valve B, shift solenoid valve C, and shift solenoid valve D.
13. Measure the resistance of each solenoid valve between the connector terminal and body ground.
Standard: 12 - 25 Ohms
^ If the resistance is out of standard, replace shift solenoid valve.
^ If the resistance is within the standard, go to step 14 and check solenoid valve for a clicking sound.
14. Connect a jumper wire from the positive battery terminal to each solenoid terminal individually.
^ If a clicking sound is heard, replace the solenoid harness.
^ If no clicking sound is heard, replace shift solenoid valve.
