After Diagnosis Is Complete

After diagnosing a problem, in addition to repairing the discovered problem, perform the verification procedure which is the last few steps at the end of almost all of the diagnostic tables. Here, you may be instructed to clear the DTCs. In order to clear the DTCs, refer to CLEARING DTCs. In order to verify a repair, you must duplicate the conditions when the customer's complaint occurs or if a DTC sets. You must duplicate the test conditions for that DTC and see if the DTC sets. Test the repair under the proper conditions for the diagnostic to run, and if the DTC does not re-set, chances are good that the repair is successful.
