TROUBLE DIAGNOSIS


Inspections before Trouble Diagnosis


CVT FLUID CHECK

Fluid Leakage and Fluid Level Check
- Inspect for fluid leakage and check the fluid level. Checking CVT Fluid .

Fluid Condition Check
Inspect the fluid condition.











STALL TEST

Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.





2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80�C (122 to 176�F). Inspect the amount of CVT fluid. Replenish if necessary.





3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.
- It is good practice to mark the point of specified engine rpm on indicator.





5. Start engine, apply foot brake, and place selector lever in "D" position.





6. While holding down the foot brake, gradually press down the accelerator pedal.
7. Quickly read off the stall speed, and then quickly remove your foot from the accelerator pedal.

CAUTION:
Do not hold down the accelerator pedal for more than 5 seconds during this test.










8. Move the selector lever to the "N" position.
9. Cool down the CVT fluid.

CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in "R" position.

LINE PRESSURE TEST

Line Pressure Test Port





(A): Line pressure Test Port.

Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80�C (122 to 176�F), then inspect the amount of CVT fluid and replenish if necessary.

NOTE:
The CVT fluid temperature rises in the range of 50 - 80�C (122 - 176�F) during 10 minutes of driving.
3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special service tool: - (OTC3492)]

CAUTION:
When using the oil pressure gauge, be sure to use the O-ring attached to the oil pressure detection plug.





4. Securely engage the parking brake so that the tires do not turn.





5. Start the engine, and then measure the line pressure at both idle and the stall speed.

CAUTION:
- Keep the brake pedal pressed all the way down during measurement.
- When measuring the line pressure at the stall speed, refer to "STALL TEST" .
6. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque below.

Torque: 7.5 N.m (0.77 kg-m, 66 in-lb)


CAUTION:
- Do not reuse O-ring.
- Apply CVT fluid to O-ring.
