After Diagnosis Is Complete

After diagnosing a problem, in addition to repairing the discovered malfunction, clear any DTC(s) set. Verify that there is proper operation. In order to verify proper operation, you must duplicate the conditions when the customer's comment occurred or if a DTC was set, you must duplicate the test conditions for that DTC (listed on the facing page of the Diagnostic Trouble Code table) and refer to conditions for setting the DTC. The DTC should not re-set after the repair has been made.
