Specification : Refer to current data as below.
This current data is nothing but an example at certain condition. Thus, the real current data and waveform could be different from this example.
Is current data normal?
When current data is similar to [Fig.3],
Go to "Catalytic converter Inspection" procedure.
When current data is similar to [Fig.4],
Go to "leakage of vacuum Inspection" procedure.
When current data is similar to [Fig.5],
Go to "PCSV Inspection" procedure.
