TCL/ASC Diagnostic Trouble Code Detection Conditions

TCL/ASC diagnostic trouble codes (TCL/ASC DTCs) are set under different conditions, depending on the malfunction detected. Most TCL/ASC DTCs will only be set during vehicle operation. Some TCL/ASC DTCs will also be set during the TCL/ASC self-check immediately after the engine is started. When you check if an TCL/ASC DTC will be displayed again after the DTC has been erased, you should duplicate the TCL/ASC DTC set conditions. Depending on the detection timing and set conditions for the specific TCL/ASC DTC, you must either drive the vehicle or turn the engine off and restart it. To set the proper conditions for that DTC again, refer to "TCL/ASC DTC SET CONDITIONS " for each TCL/ASC DTC that you are trying to reset.
