Pressure Test
Pressure TestSpecial Tools Required
^ A/T oil pressure gauge set w/panel 07406-0020400 or 07406-0020401
^ A/T pressure hose, 2,210 mm 07MAJ-PY4011A
^ A/T pressure hose adapter 07MAJ-PY40120
NOTE: There may come ABS DTC(s) during the pressure test. If the ABS DTC(s) comes on, clear the ABS DTC(s) with the HDS.
1. Make sure the transmission fluid is filled to the proper level.
2. Raise the vehicle on a lift, or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Remove the splash shield.
5. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover, and go to the A/T Mod Menu.
6. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting.
7. Connect the A/T oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the ports while connecting the gauges.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port in P or N while holding the engine speed at 2,000 rpm.
10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection port.
11. 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.
12. Remove the air cleaner assembly and the intake air duct.
13. Connect the A/T oil pressure gauge to the 1st clutch pressure inspection port (B). Then temporarily install the air cleaner assembly and the intake air duct.
14. Connect the A/T oil pressure gauge to the 2nd clutch pressure inspection port (C).
15. Start the engine, and shift to 1.
16. Measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) while holding the engine speed at 2,000 rpm.
17. 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.
18. Turn the engine off, remove the air cleaner assembly and the intake air duct, then disconnect the A/T oil pressure gauges from the 1st clutch pressure and the 2nd clutch pressure inspection ports.
19. Install the sealing bolts to 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 washer.
20. Install the intake air duct and the air cleaner assembly.
21. Connect the A/T oil pressure gauge to the 3rd clutch pressure inspection port (D) and the 4th clutch pressure inspection port (E).
22. Connect the A/T oil pressure gauge to the 5th clutch pressure inspection port (F)
23. Select Pressure Test Assistance Mode in the Miscellaneous Test Menu of the A/T Mode Menu.
24. Start the engine, and shift to D3.
25. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.
26. Shift to D, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E) and the 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.
27. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.
28. Shift to R, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure the 5th clutch pressure at the 5th clutch pressure inspection port (F)
29. Turn the engine off, then disconnect the A/T oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.
30. 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 washer.
31. If the pressures are out of the service limit, problems and probable causes are listed in the table.
32. Install the splash shield.
