Hydraulic Test

HYDRAULIC TEST




a. Measure the line pressure.

NOTE:
- Do the test at the normal operation fluid temperature the 50 - 80 °C (122 - 176 °F).
- The line pressure test should always be carried out in pairs. One technician should observe the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
- Be careful to prevent SST's hose from interfering with the exhaust pipe.
- This check must be conducted after checking and adjusting engine.
- Do under condition that A/C is OFF.
- When being stalled, do not continue more than 10 seconds.

1. Warm up the ATF.
2. Lift the vehicle up.
3. Remove 4 screws and 4 clips, and remove the engine under cover No.1.
4. Remove 2 bolts and 2 clips, and remove the front fender apron seal LH.
5. Remove 7 clips and remove radiator lower air deflector.
6. Remove 2 bolts off and remove the air cleaner inlet No.1.
7. Remove a bolt off and remove the air cleaner inlet No.1.

HINT: Remove air cleaner, take 3 bolts off to raise the air cleaner case, and remove the air cleaner inlet No.1.

NOTE: Do not apply excessive force to the resonator.

8. Connect OBD II scan tool or hand-held tester to DLC3.
9. Remove the test plug A, install the SST and start engine.

SST 09992-00095 (09992-00231, 09992-00271)

NOTE: There is a difference in installation point between D position and R position.

10. Using OBD II scan tool or hand-held tester, shift to D position and hold 3rd by active test, and measure the line pressure in idling.




Specified line pressure

11. Turn the ignition switch OFF.
12. Disconnect 2 connectors of transmission wire.

HINT: Disconnect the 2 connectors only when performing the D position stall test.

13. Start engine.
14. Depress the brake pedal strongly, shift to D position, depress the accelerator pedal all the way down and check the line pressure in being stalled.




Specified Line Pressure

15. Turn the ignition switch OFF.
16. Remove the SST install the test plug A.
17. Remove the test plug B, install the SST and start engine.

SST 09992-00095 (09992-00231, 09992-00271)

18. Connect 2 connectors of transmission wire, depress the brake pedal strongly, shift to R position and check the line pressure in idling and being stalled.




Specified Line Pressure

19. Remove the SST, install the test plug B.
20. Clear the DTC.
