STOP AND START SYSTEM(for 2AR-FE) DTC CHECK / CLEAR

Tech Tips


  • 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.
