9. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 2 and 

body ground. 

Is there continuity? 

YES: Go to step 10.  

NO: Repair open in the wire between the A/T clutch pressure control solenoid valve A and 
ground (G101), or repair poor ground (G101), then go to step 12 .

10. Turn the ignition switch ON (II).  

11. Measure the voltage between A/T clutch pressure control solenoid valve A connector terminals No. 1 and 

No. 2. 

Is there about 11 V as the ignition switch is turned to the ON (II) position? 

YES: Update the PCM if it does not have the latest software, or substitute a known-good 
PCM (see PCM UPDATING & SUBSTITUTION FOR TESTING ), then recheck. If the 
symptom/indication goes away with a known-good PCM, replace the original PCM.  

NO: Repair open or short in the wire between PCM connector terminal C1 and A/T clutch

12. Clear the DTC with the HDS.  

13. Test-drive the vehicle for several minutes in the D position in all five gears.  

14. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0962. 

Did the result indicate a pass? 

YES: The problem has been corrected.  

NO: Return to step 1 and recheck.

1. Clear the DTC with the HDS.  

2. Check that DTC P0963 recurs. 

Is DTC P0963 indicated? 

YES: Go to step 6 .  

NO: Go to step 3.  

3. Select P CTRL SOL CONTROL in MISC. TEST MENU, then select P. CONTROL SOL A in P CTRL 

SOL CTRL MENU with the HDS.  

4. Drive with the A/T clutch pressure control solenoid valve A at 0.2 A in SOL A CONTROL menu.  

5. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0963. 

Did the result indicate a fail? 

YES: Go to step 6.  

NO: Intermittent failure, the system is OK at this time. Check for poor connections or loose 
terminals at the A/T clutch pressure control solenoid valve A and PCM. If the tester indicates 
NOT COMPLETE, return to step 3 and recheck.  

6. Turn the ignition switch OFF.  

7. Disconnect the A/T clutch pressure control solenoid valve A connector.  

8. Measure A/T clutch pressure control solenoid valve A resistance at the solenoid connector. 

Is there 3-10 ohm? 

YES: Go to step 9.  

NO: Replace the A/T clutch pressure control solenoid valve A (see A/T CLUTCH 
PRESSURE CONTROL SOLENOID VALVE A REPLACEMENT
 ), then go to step 
12 .
