01-24 INTRODUCTION - HOW TO TROUBLESHOOT

01 The table shows DTCs and corresponding test procedures. Troubleshooting by the table will
substantially improve your efficiency and accuracy.

Defects
Defects deliver the possible causes (such as circuit or part) of each defect as follows. When
the analyzer displays that the system is working properly, yet the defect remains, troubleshoot
by the defect list. The number in the table refers to the sequence of circuit or part check.

If the vehicle diagnostics system cannot find the defect, while the symptom actually exists,
it means the defect exceeds the scope of the system.
