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.

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).

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 Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu with the
HDS.
4. Test A/T clutch pressure control solenoid valve A with the HDS.
 If the valve tests OK, the test is complete. Disconnect the HDS.
 If the valve does not test OK, follow the instructions on the HDS.
 If the valve does not test OK, and the HDS does not determine the cause, go to step 5.
5. Remove the intake air duct (see page 11-348) and the air cleaner assembly (see page 11-345). 6. Disconnect the A/T clutch pressure control solenoid
valve A connector (A).
7. Measure the resistance between A/T clutch pressure control solenoid valve A connector
terminals No. 1 and No. 2.
 If the resistance is within the standard, go to step 8.
 If the resistance is out of standard, replace A/T clutch pressure control solenoid valve A
(see page 14-221).
8. Connect a jumper wire from the negative battery terminal to solenoid valve A connector terminal
No. 2, and connect another jumper wire from the
positive battery terminal to connector terminal
No. 1.
 If a clicking sound is heard, the valve is OK, and the test is complete, go to step 18.
 If no clicking sound is heard, go to step 9.
