FLOWCHART 



Use the following flowchart to verify the cause of the trouble. 

NOTE:



While performing the inspection of the past malfunction code, the 
applicable DTCs may be added to memory by removing or disconnecting 
the related parts. Inspect only the DTCs that were indicated before 
inspecting.

When DTCs of the present malfunction are no longer output after present 
or past malfunctions or both have been repaired, be sure to perform past 
malfunction display cancellation to prevent repair of malfunctions that 
have already been repaired.
