DTCs, which are stored in the engine stop and start ECU, can be displayed on the GTS. The GTS can display confirmed and pending DTCs.
Some DTCs are not stored if the engine stop and start ECU 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.
