SFI SYSTEM PRECAUTION


  1. FOR USING INTELLIGENT TESTER

    CAUTION:

    Observe the following items for safety reasons:


    • Read its instruction books before using the tester.

    • Prevent the tester cable from being caught on the pedals, shift lever and steering wheel when driving with the tester connected to the vehicle.

    • When driving the vehicle for testing purposes using the tester, 2 persons are required. One drives the vehicle, and the other operates the tester.

  2. DISCONNECT AND RECONNECT CABLE OF NEGATIVE BATTERY TERMINAL

    *1 Cable
    *2 Negative (-) Battery Terminal

    1. Before performing electronic work, disconnect the cable from the negative (-) battery terminal in order to prevent it from shorting and burning out.

    2. Before disconnecting and reconnecting the battery cable, turn the power switch off and the headlight dimmer switch OFF. Then loosen the terminal nut completely. Do not damage the cable or terminal.

    3. When the battery cable is disconnected, the clock and radio settings and stored DTCs are erased. Therefore, before disconnecting the battery cable, make a note of them.

      Note

      When the cable is disconnected from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected.

  3. PRECAUTIONS FOR INSPECTING HYBRID CONTROL SYSTEM


    1. Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

      Note

      After removing the service plug grip, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY) unless instructed by the repair manual.

    2. After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals.

      Tech Tips

      Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

  4. PRECAUTIONS FOR HYBRID CONTROL SYSTEM ACTIVATION


    1. When the warning light is illuminated or the auxiliary battery has been disconnected and reconnected, attempting to put the vehicle into the power switch on (READY) state the first time may not start the system. If so, turn the power switch off and reattempt to put the vehicle into the power switch on (READY) state.
