U)�:
After viewing or printing the Troubleshooting Chart, refer to the diagnostic codes or symptoms which are listed in the left column. All of the Self-Diagnosis, Preliminary Checks and Diagnostic Procedures are located in On-Board Diagnostic System.
The dark-colored circles with numbers inside are the areas to check in the order of the number. For example, number 1 would be checked first, number 2 next, and so on.
The empty circles will send you to a check, but do not have any order.
