  1. INITIALIZATION 
    NOTE:
    • Perform initialization (throttle position) after replacing the throttle body assembly or cleaning any throttle body components.
    • Perform initialization (throttle position) after reconnecting the battery cable or replacing the ECM.
    • Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM (See INITIALIZATION ).
    • Perform the REGISTRATION (VIN registration) when replacing the ECM (See REGISTRATION  ).
    • If the ECM has been replaced or RESET MEMORY (AT initialization) has been performed, set up the function of the ATF (Automatic Transmission Fluid) temperature warning light (See INITIALIZATION ).

    HINT:

    Initialization cannot be completed by only removing the battery.

  2. FOR USING TECHSTREAM 
    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, two persons are required. One is for driving the vehicle, and the other operates the tester.
  3. DISCONNECT AND RECONNECT CABLE OF 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 ignition 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.
