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:
^ Disable the VSA by pressing the VSA OFF switch.
^ VSA DTC(s) may come on during the test-drive. If the VSA DTC(s) come on, clear the 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 the rear wheels, and raise the front of the vehicle. Make sure it is securely supported, and allow the front wheels to rotate freely.
3. Remove the front inner fender and splash shield.
4. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
5. Turn the ignition switch to ON (II).
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 port while connecting the gauge.
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 (A) with the shift lever in P or N, while holding the engine speed at 2,000 rpm.
10. Turn the engine off, then disconnect the 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 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washer.
12. Remove the engine cover and the intake air duct.
13. Connect the A/T oil pressure gauge to the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure inspection port (C).
14. Connect the A/T oil pressure gauge to the 2nd clutch pressure inspection port (D). Then temporarily install the intake air duct.
15. Start the engine with the shift lever in P, then shift the shift lever to 1.
16. Measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure at the 1st-hold clutch pressure inspection port (C) while holding the engine speed at 2,000 rpm.
17. Shift the shift lever to 2, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.
18. Turn the engine off, then disconnect the A/T oil pressure gauges from the 1st clutch pressure, 1st-hold clutch pressure, and 2nd clutch pressure inspection ports.
19. Install the sealing bolts in the 1st clutch pressure, 1st-clutch hold clutch pressure, and the 2nd clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
20. Connect the A/T oil pressure gauge to the 3rd clutch pressure inspection port (E) and the 5th clutch pressure inspection port (G).
21. Connect the A/T oil pressure gauge to the 4th clutch pressure inspection port (F).
22. Start the engine with the shift lever in P. Press the brake pedal, shift the shift lever to D and select D3 driving mode by pressing the D3 switch.
23. Release the brake pedal; the transmission is in 1st gear.
24. Press the accelerator pedal to increase the engine speed to 2,500 rpm, then shift to 2nd gear.
25. Release the accelerator pedal slowly to close the throttle over 5 seconds; let the engine speed decreases to 1,000 rpm with the transmission in 2nd gear.
26. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 rpm in 5 seconds, and hold the accelerator; shift to 3rd gear and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (E) while holding the engine speed at 2,000 rpm.
27. Press the D3 switch one more time, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.
28. Measure the 5th clutch pressure at the 5th clutch pressure inspection port (G) while holding the engine speed at 2,000 rpm.
29. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.
30. Shift the shift lever 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 (G).
31. Turn the engine off, then disconnect the A/T oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.
32. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
33. If the pressures are out of the service limit, problems and probable causes are listed in the table.
34. Install the intake air duct and the engine cover.
35. Install the front inner fender and the splash shield.
