Inspection Procedure

NOTE: Be sure to read DESCRIPTION before performing the following procedures.
  1. CHECK FOR DTC OF OTHER COMPONENTS 
    1. Check if the component shown by the sub-code is displayed in the check result of the other components.
      1. Check if "01-DC" is output for the other components.
      2. If "01-DC" is output for any other components, check if the same physical address is displayed.

        HINT:

        For the list of the components shown by sub-codes, refer to the table in the next step.
