ENTRY AND START SYSTEM(for Start Function) CHECK FOR INTERMITTENT PROBLEMS

Note


  • The cause of a malfunction is stored in the RAM or EEPROM in the certification ECU (smart key ECU assembly). As the cause of a malfunction stored in the RAM will be cleared when the cable is disconnected from the negative (-) battery terminal, do not disconnect the cable from the negative (-) battery terminal before checking and recording are complete.

  • If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before operation history has been read and saved, the operation history information could be lost.

  • The function "Read operation history" uses the current system time setting inside the GTS and the time counter inside the controlling ECU to calculate the timings shown in the operation history. For this reason, before reading out the operation history, first make sure that the GTS system clock is accurately set to the current time.


  1. OPERATION HISTORY

    Tech Tips

    The certification ECU (smart key ECU assembly) stores the operation history of the entry and start system and it can be read using the GTS.


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Entry&Start / Utility / Operation History / Certification ECU operation log of ID code registration, Radio wave interference or Radio wave interference 2.


      Body Electrical > Entry&Start > Utility
