  2. CUSTOMER PROBLEM ANALYSIS 

    HINT: 

    • In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
    • Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
    • The following 5 items are important points for problem analysis:
      What Vehicle model, system name
      When Date, time, occurrence frequency
      Where Whether the problem occurs at a specific location
      Under what conditions? Whether the doors were locked or unlocked, whether the engine switch was on, whether the engine was running
      How did it happen? Problem symptoms

    See step  3

  3. INSPECT BATTERY VOLTAGE 
    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.

      HINT: 

      A simple method to determine whether the battery is discharged is to operate the horn.

  4. TURN ENGINE SWITCH ON (IG) 

    HINT: 

    When using the Techstream with the engine switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.
