After Diagnosis Is Complete

After diagnosing a problem, in addition to repairing the discovered fault, it is a good idea to clear any trouble codes set and verify proper operation. To clear codes, refer to HOW TO OPERATE DIAGNOSTICS . To verify proper operation, you must duplicate the conditions when the customer's complaint occurred or if a code was set, you must duplicate the test conditions for that code and see if the code sets. If the code does not set, chances are good that the problem is repaired.
