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. Refer to "ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION", and "TROUBLE DIAGNOSIS FOR SYMPTOMS".
