ROAD TEST
Description
^ The road test inspects overall performance of the A/T and analyzes possible malfunction causes.
^ The road test is carried out in the following three stages.
1. Check before engine is started.
2. Check at idle.
3. Cruise test
^ Inspect all the items from Part 1 to Part 3.
^ Before beginning the road test, check the test procedure and inspection items.
^ Test all inspection items until the symptom is uncovered. Diagnose NG items when all road tests are complete.
