Description
- The purpose of this test is to determine the general performance characteristics of the CVT and to analyze the causes of malfunctions.
- The road test includes the following three parts.
1. Check before starting the engine. See below.
2. Check at idle speed. See below.
3. Check in motion. See below.
- Before performing a road test, be familiar with all procedures and components that need to be tested.
- Test all components until you detect any signs of failure. Troubleshoot any components that fail the road test.
- Procedure for setting up the CONSULT-III tester
