DTC Check/Clear

WARNING: This page is about a different car, the 2009 Toyota Tacoma. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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 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 current and pending DTCs.
Some DTCs are not set 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.
The pending DTCs are set when the malfunction is detected once.
