DTC Check/Clear

NOTE:

If no DTC appears in normal mode:
On the hand-held tester check the pending fault code using the Continuous Test Results function (Mode 7 for SAE J1979).
When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode will be erased. Before changing modes, always check and make a note of DTCs and freeze frame data.
