Stall Speed Test

CVT Stall Speed Test

1. Make sure the transmission fluid is filled to the proper level CVT Fluid Level Check.

2. Apply the parking brake, and block all four wheels.

3. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.





4. Turn the ignition switch to ON (II).

5. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting DLC Circuit Troubleshooting (PGM-FI System).

6. Check the IMA battery charge level. If the IMA battery level indicator displays no level, hold the engine speed between 3,500 and 4,000 rpm without load (in P or N) until the level in the indicator is half full.

7. Make sure the A/C switch is OFF.

8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).

9. Shift the shift lever to D while pressing the brake pedal firmly, then press the accelerator pedal to the floor for 6 to 8 seconds, and note the engine speed. Do not move the shift lever while raising the engine speed.

10. Allow 2 minutes for cooling, then repeat the test with the shift lever in S, L, and R.

NOTE:

- Do not test stall speed for more than 10 seconds at a time.
- Stall speed tests should be used for diagnostic purposes only.
- Do not test stall speed with the A/T pressure gauges installed, there is danger that exceeds the resisting pressure limit of the A/T pressure gauge.
- Do not move the shift lever while raising the engine speed.
