        Tech Tips

        The smart key ECU assembly constantly stores the present power source mode in its memory. Therefore, if the power to the smart key ECU assembly is interrupted due to the removal of the battery, the smart key ECU assembly restores the power source mode after the battery is reconnected. For this reason, if the battery is removed when the engine switch is in any position other than off, the power will be restored to the vehicle at the same time the power is restored to the smart key ECU assembly (by reconnecting the battery). Therefore, before removing or disconnecting the battery, make sure to turn the engine switch off.

  5. DIAGNOSIS


    1. The smart key ECU assembly can detect malfunctions in the start function when the power source mode is on (IG). At the same time, the ECU stores the 5-digit DTC in the memory.

    2. The DTC can be read by connecting a Grobal TechStream (GTS) to the DLC3.

    3. The start function cannot be operated again if a malfunction occurs.

    4. For details, refer to the corresponding Repair Manual for this model.
