Flowchart [Climate Control Unit (Full-Auto Air Conditioner)]

• Use the following flowchart to verify the cause of the problem.
  NOTE:

  • When inspecting past malfunction codes, inspect only the DTCs that were indicated before beginning the inspection. A mis-diagnosis could occur as a result of new DTCs being added while performing an inspection by disconnecting related parts or connectors.
  • When DTCs of the present malfunction are no longer output after present or past malfunctions or both have been repaired, always clear the past malfunction from memory to prevent repair of malfunctions that have already been repaired.
