Pressure Test

Pressure Test

Special Tools Required
^ A/T oil pressure gauge set 07406-0020400 or 07406-0020401
^ A/T pressure hose, 2,210 mm 07MAJ-PY4011A
^ A/T pressure hose adapter 07MAJ-PY40120

1. Make sure the transmission fluid is filled to the proper level.
2. 4WD model: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
3. Remove the splash shield.
4. Connect the oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the hole while connecting the gauge.





5. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
6. Turn off the engine, and connect the HDS to the DLC (A).





7. With the shift lever in P or N and holding the engine speed at 2,000 rpm, measure the line pressure.





8. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection port.
9. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and tighten the bolt to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washer.
10. Connect the oil pressure gauge to the 1st clutch pressure inspection port (B).





11. Remove the air cleaner housing and the intake air duct, and connect the oil pressure gauge to the 2nd clutch pressure inspection port (C). Then temporarily install the air cleaner housing and the intake air duct.





12. Start the engine.
13. Shift to 1, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) while holding the engine speed at 2,000 rpm.
14. Shift to 2, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (C) while holding the engine speed at 2,000 rpm.





15. Turn the engine off, and remove the air cleaner housing and the intake air duct. Then disconnect the oil pressure gauges from the 1st clutch pressure and the 2nd clutch pressure inspection ports.
16. Install the sealing bolts in the 1st clutch pressure and the 2nd clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
17. Install the air cleaner housing and the intake air duct.
18. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (D) and the 5th clutch pressure inspection port (F).





19. Connect the oil pressure gauge to the 4th clutch pressure inspection port (E).





20. Cancel the transmission 2nd-hold control mode with the HDS; choose Pressure Test Assistance Mode in the Miscellaneous Test Menu of the A/T Mode Menu.
21. Start the engine, shift to D, and select the D3 driving mode by pressing the D3 switch.
22. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.
23. Release the D3 driving mode by pressing the D3 switch, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E) while holding the engine speed at 2,000 rpm.
24. Measure the 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.





25. Bring the engine back to an idle, then press the brake pedal to stop the wheels from rotating.
26. Shift to R, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E).





27. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.
28. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
29. If the pressures are out of the service limit, refer to the possible problems and probable causes listed in the table.





30. Install the splash shield.
