CVT Stall Speed Test (CVT)
CVT Stall Speed Test
1. Make sure the transmission fluid is filled to the proper level CVT Fluid Level Check (CVT).
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 (F-CAN, IMA-CAN, K-LINE).
6. Check the SOC in the DATA LIST with the HDS. If the SOC indicates less than 50%, hold the engine speed at 3,500 rpm without load (in P or N) until the SOC indicates at least 50%.
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 with the Normal Mode 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 D with the ECON Mode and the Sport Mode.
11. Allow 2 minutes for cooling, then shift the shift lever to D. Press the paddle shifter + (upshift switch) and the paddle shifter - (downshift switch) at the same time, and hold them for about 5 seconds. Check that the shift indicator displays L, then repeat the test in the L mode.
12. Allow 2 minutes for cooling, then repeat the test with the shift lever in 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.
