- 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 the DTCs later in this section. In order to verify a repair, you must duplicate the conditions when the customer's complaint occurred or if a DTC was set, you must duplicate the test conditions for that DTC (listed on the facing page of the trouble chart) and see if the DTC sets. If the DTC does not re-set and the repair was tested under the proper conditions for the diagnostic to run, chances are good that the problem is repaired.
