Description
- The purpose of this test is to determine the general performance characteristics of the CVT and to analyze the causes of failures.
- The road test consists of the following three parts.
1. Check before starting the engine. See below.
2. Check at idle speed. See below.
3. Test in motion. See below.
- Before performing a road test, familiarize yourself with all procedures and components that need to be checked.
- Test all components until signs of failure are found. Troubleshoot any components that fail the road test.

In sport mode.
Move the selector lever to the "D" and "L" positions and check if the vehicle moves forward.
Does the car move forward in all positions?
Yes → Proceed to "Test on the move" below.
No → Stop road test.
Testing in motion
1. Check the vehicle speed and gear shifting - part 1.
1. Drive the vehicle for approximately 10 minutes and warm up the engine oil and CVT fluid to operating temperature.
Operating temperature of CVT fluid is 50-80°C.
2. Stop the car on a level surface.
3. Move the selector lever to position "P".
4. Start the engine.
5. Move the selector lever to position "D".
6. Accelerate the car by continuously pressing the accelerator pedal until the throttle valve is opened by 2/8.
Using the CONSULT-III tester, read the vehicle speed and engine speed.
Normal or abnormal?
Normal → Proceed to step 2.
Abnormal → Continue road test.
1. Check the vehicle speed and gear shifting - part 2.
