Road Test

DESCRIPTION





- The purpose of the test is to determine overall performance of A/T and analyze causes of problems.
- The road test consists of the following three parts:
1. Check before engine is started
2. Check at idle
3. Cruise test





- Before road test, familiarize yourself with all test procedures and items to check.
- Conduct tests on all items until specified symptom is found. Troubleshoot items, which check out No Good after road test.
