Terminals No. 2 & No. 3

7. Turn the ignition switch ON (II).

8. Measure the voltage between transmission gear selection switch connector terminal No. 3 and body

ground.

Is there about 5 V?

YES: Repair open in the wire between transmission gear selection switch connector terminal
No. 2 and ground (G501), or repair poor ground (G501), then go to step 10 .

NO: Go to step 9.

9. Measure the voltage between PCM connector terminal D2 and body ground.

Is there about 5 V?

YES: Repair open in the wire between PCM connector terminal D2 and the transmission
gear selection switch connector, then go to step 10.

NO: Check for loose or poor connections at PCM connector terminal D2. If the connection is
OK, 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.

10. Clear the DTC with the HDS.

11. Start the engine in the P position, wait for more than 10 seconds, then shift to the M position.

12. Push the shift lever toward shiftup position (+) slowly, and return to neutral position; repeat this test 10

times or more.

13. Pull the shift lever toward shiftdown position (-) slowly, and return to neutral position; repeat this test 10

times or more.

14. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0958.

Did the result indicate a pass?

YES: The problem has been corrected.

NO: Return to step 1 and recheck.

DTC P0962: PROBLEM IN A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A CIRCUIT

1. Clear the DTC with the HDS.

2. Check that DTC P0962 recurs.

Is DTC P0962 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 1.0 A in SOL A CONTROL menu.

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

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 .
