1. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select Shift Solenoid Valves A, B, C, D, and E Test in the Miscellaneous Test Menu with the HDS.
4. Check that shift solenoid valves A, B, C, D, and E 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 5, and test the solenoid valve.
5. Do the battery removal procedure (see page 22-69).
6. Remove the intake air duct (see page 11-348) and the air cleaner assembly (see page 11-345).
7. Remove the battery tray, the battery base, and the resonator.
8. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of
the vehicle. Make sure it is securely supported.
9. Remove the splash shield. 10. Remove the drain plug (A), and drain the automatic
transmission fluid (ATF).
11. Reinstall the drain plug with a new sealing washer (B).
12. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).

13. Disconnect the shift solenoid wire harness
connector, and remove it from the transmission
housing.
14. Measure the shift solenoid valve resistance between the following shift solenoid wire harness
connector terminals and body ground:
 No. 1 (GRN): Shift solenoid valve C
 No. 2 (ORN): Shift solenoid valve B
 No. 3 (RED): Shift solenoid valve E
 No. 5 (BLU): Shift solenoid valve A
 No. 8 (YEL): Shift solenoid valve D
15. If the resistance is within the standard, go to step 17 and check the solenoid valve for a clicking
sound. If the resistance is out of standard, go to
step 16.
16. Disconnect the shift solenoid valve connector, and measure the resistance at the solenoid valve
connector. Replace the shift solenoid valve if the
resistance is out of standard, then go to step 20.
17. Connect a jumper wire from the battery positive terminal to the shift solenoid wire harness
connector terminals, and connect another jumper
wire from the battery negative terminal to body
ground individually. A clicking sound should be
heard.
 If a clicking sound is heard, the valves are OK, and the test is complete, connect the connector.
 If no clicking sound is heard, replace the shift solenoid valve (see page 14-217). 18. Replace the shift solenoid harness if the test results
are OK.
19. Install a new O-ring on the shift solenoid wire harness connector, and install the connector in the
transmission housing.
20. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
21. Check the shift solenoid wire harness connector for rust, dirt, or oil, then connect the connector
securely.
22. Refill the transmission with ATF (see step 5 on page 14-232).
23. Install the battery tray, the battery base, and the resonator.
24. Install the air cleaner assembly (see page 11-345) and the intake air duct (see page 11-348).
25. Do the battery installation procedure (see page 22-69).
26. Install the splash shield.

solenoid valve D.
NOTE: Do not install shift solenoid valves A and B
before installing shift solenoid valve D and E. If
shift solenoid valve A or B is installed before
installing shift solenoid valve D or E, it may
damage to hydraulic control system.
