DTC Check / Clear
TX6A AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: DTC CHECK / CLEAR; 2013 MY FR-S [03/2012 -]
NOTICE:
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 are cleared. 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, pending and permanent DTCs.
* If a malfunction is detected during the current driving cycle, current and permanent DTCs are stored.
* Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
* Current and pending DTCs can be cleared by using the Techstream. However, permanent DTCs cannot be cleared using either of these two methods.
* After clearing current DTCs using the Techstream, permanent DTCs can be cleared when the system is determined to be normal for the relevant DTCs and then the universal trip is performed.
