CVT Stall Speed Test

Service Information

CVT Stall Speed Test

Test

1. CVT Fluid Level - Check





NOTE:
* Keep all foreign particles out of the transmission.
* Check the CVTF level within 60-90 seconds after turning the engine off.
* Higher CVTF level may be indicated if the radiator fan comes on twice or more.

1. Park the vehicle on the level ground.

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

3. Remove the dipstick (yellow loop) (A) from the dipstick tube, and wipe it with a clean cloth.

4. Insert the dipstick back into the dipstick tube.





5. Remove the dipstick, and check the CVTF level. It should be between the upper mark (A) and the lower mark (B) on the HOT level in tip of the dipstick (C).

6. If the CVT fluid level is below the lower mark, check for fluid leaks at the transmission, the CVTF filter, the CVTF cooler hoses, and the CVTF cooler lines. If a problem is found, fix it before filling the transmission with CVTF.

NOTE: If the vehicle is driven when the CVTF level is below the lower mark, one or more of these symptoms may occur:
* Noise from transmission in D, S, L, and R.
* Engine runs, but vehicle does not move in any position.
* No shift to a higher ratio or lower ratio.
* Flares while driving.
* Excessive shock when accelerating and decelerating.
* Vehicle does not creep on a flat road in D, S, and L.
* Late shift after shifting from N to D or N to R.
* Unstable rpm while driving.
* Stall speed high.

7. If the level is above the upper mark, drain the CVTF to proper level.





8. If necessary, fill the transmission with CVTF through the dipstick tube opening (A) to bring the fluid level between the upper mark and the lower mark of the dipstick. Do not fill the fluid above the upper mark. Always use Honda CVTF. Using a non-Honda CVTF can affect shift quality.





9. Insert the dipstick (A) with the dot (B) on the handle facing to the left of the vehicle.

2. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

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

3. Make sure the HDS communicates with vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

3. CVT Stall Speed - Test

Check the IMA battery level. If the IMA battery level indicator displays three segments or less, apply the parking brake, then start the engine with the shift lever in P or N, and hold it between 3,500 rpm and 4,000 rpm without load until the level in the indicator displays half of its segments

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

2. Make sure the A/C switch OFF.

3. After the engine has warmed up to normal operating temperature (the radiator fan comes on twice).

4. Shift to D while pressing the brake pedal firmly, then press the accelerator pedal for 6 to 8 seconds, and note the engine speed. Do not move the shift lever, or remove your foot off the brake, while raising the engine speed.

5. Allow 2 minutes for cooling, then repeat the test in S, L, and R.

NOTE:
* Do not test stall speed for more than 10 seconds at a time.
* Record the engine speed at 6 - 8 seconds after pressing the accelerator pedal. Higher engine speed will be indicated for 5 seconds
* Stall speed test result should be used for diagnostic purposes only.
* The stall speed should be the same in D, S, and L.
* Do not test stall speed with a pressure gauge installed.








* If any of the stall speeds are out of the service limit, refer to the stall speed test problem and probable causes are listed.
