DTC CHECK / CLEAR
NOTE:
When the diagnosis system is changed from the normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode are erased. Before changing modes, always check and make a note of DTCs and freeze frame data.
HINT:
- DTCs which are stored in the ECM can be displayed on the Techstream. The Techstream can display the current and pending DTCs.
