Step 8: A/T basic check and trouble diagnosis group

Perform A/T basic check according to "A/T Basic Check:" first. When the end of the flow has been reached, check the parts of the system suspected as a possible cause referring to "GROUP 1 ", "GROUP 2 " or "GROUP 3 " of "A/T Basic Check:" and based on symptoms appearing on the vehicle (symptoms obtained through steps of customer complaint analysis, trouble symptom confirmation and/or "A/T Basic Check:") and repair or replace faulty parts, if any.
