NOTICE:

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 notice before proceeding with work (Click here).

NOTICE:

1. Do not reuse the drained coolant because it may contain foreign objects.
   
2. Collect the drained coolant and measure its volume to establish a benchmark. When adding coolant, make sure to add more coolant than the measured amount.
   

1. Remove the reserve tank cap.
   

   CAUTION:

   To avoid the danger of being burned, do not remove the reserve tank cap while the coolant for the inverter is still hot.

2. Using a hexagon wrench (10 mm), remove the drain plug indicated in the illustration and drain the coolant.
   

   CAUTION:

   Use caution when handling coolant immediately after driving or in summer because it may be hot.

3. Install the plug with a new gasket.
   

   Torque:

CAUTION:

Wear insulating gloves.

1. Remove the 9 bolts and inverter cover.
   

   NOTICE:

   Make sure to pull the inverter cover straight up, as a connector is connected to the bottom of the cover.

CAUTION:

Wear insulating gloves.

NOTICE:

Do not allow any foreign objects or water to enter the inverter with converter assembly.

1. Using a voltmeter, measure the voltage between the terminals of the 2 phase connectors.
   

   Standard voltage:

   0 V
   

   HINT:

   Use measuring range of DC 750 V or more on the voltmeter.

CAUTION:

Wear insulating gloves.

NOTICE:

1. Insulate the disconnected terminals with insulating tape.
   
2. Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
   

1. Disconnect the 2 harness clamps.
   

2. Remove the 4 bolts, and disconnect the frame wire (high voltage cables of the hybrid battery) from the inverter with converter assembly.
   

CAUTION:

Wear insulating gloves.

NOTICE:

1. Insulate the disconnected terminals with insulating tape.
   
2. Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
   

1. Turn back the wire harness cover and release the cable.
   

2. Remove the 5 bolts, and disconnect the high voltage cables of the generator cable (MG1) from the inverter with converter assembly.
   

CAUTION:

Wear insulating gloves.

NOTICE:

1. Insulate the disconnected terminals with insulating tape.
   
2. Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
   

1. Disconnect the harness clamp.
   

2. Remove the 5 bolts, and disconnect the high voltage cables of the motor cable (MG2) from the inverter with converter assembly.
   

CAUTION:

Wear insulating gloves.

NOTICE:

1. Insulate the disconnected terminals with insulating tape.
   
2. Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
   

1. Remove the 4 bolts, and disconnect the No. 2 engine wire (high voltage cables for the air conditioning compressor) from the inverter with converter assembly.
   

2. Disconnect the harness clamp.
   

1. Temporarily install the inverter cover with the 9 bolts to prevent any foreign objects or water from entering the inverter with converter assembly.
   

1. Remove the relay block cover.
   

2. Release the 2 clamps, and remove the No. 1 relay block cover.
   

3. Remove the bolt from the No. 2 engine room wire.
   

4. Release the 2 claws, and disconnect the No. 2 engine room wire.
   

5. Connect the No. 2 engine room wire to the protector.
   

1. Release the retainer and disconnect the water hose from the inverter with converter assembly.

3. Disconnect the coolant hose from the inverter with converter assembly. Put a piece of cloth in the pipe and in the disconnected hose or cover the pipe and hose with plastic bags as shown in the illustration, so that foreign matter doesn't stick to the union or the inside of the connector and to prevent coolant from spilling near the inverter with converter assembly.
   

CAUTION:

Wear insulating gloves.

1. Remove the 3 bolts and inverter with converter assembly.
   

   NOTICE:

   1. Since the inverter with converter assembly is very heavy, 2 people are needed to remove the inverter with converter assembly. When removing the inverter with converter assembly, do not damage the parts around it.
      
   2. To prevent damage, do not hold the inverter with converter assembly by the connectors.
      
   3. To prevent damage due to static electricity, do not touch the terminals of the disconnected connectors.
      

2. Even after the coolant is drained, coolant remains in the inverter due to its internal structure. Therefore, seal or cover the pipes when removing the inverter so that coolant does not spill out.
   

1. Remove the 2 bolts and motor cable bracket.
   

CAUTION:

Wear insulating gloves.

HINT:

Perform this procedure only when replacement of the high voltage fuse is necessary.

1. Remove the 9 bolts and inverter cover.
   

   NOTICE:
