  3. READ OUT AND SAVE OPERATION HISTORY

    Note


    • 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 out 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. Read out and save operation history using the GTS.

  4. PRE-CHECK


    1. Measure the battery voltage.

      Standard voltage
      11 to 14 V

      If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

    2. Check the fuses and relays.

    3. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
