  2. 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 turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

      • 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 removing 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.

  3. NOTICE FOR HYBRID CONTROL SYSTEM ACTIVATION


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

  4. WHEN USING GTS

    CAUTION:

    Observe the following items for safety reasons:


    • Before using the GTS, read the instruction manual.

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

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

  5. COOLING FAN SYSTEM

    CAUTION:

    The cooling fans may continue to operate after the power switch is turned off. Be careful not to bring your hands or tools near the cooling fans while they are operating.

    Tech Tips

    The cooling fans may continue to operate for up to 8 minutes after the power switch is turned off if the following conditions are met after driving under high load:


    • The engine coolant temperature is extremely high.

    • The outside air temperature is extremely high.
