PRECAUTION
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 notice before proceeding with work Click here.
REMOVE SERVICE PLUG GRIP
REMOVE NO. 1 ENGINE UNDER COVER
DRAIN COOLANT (for Inverter)
Note
Do not reuse the drained coolant because it may contain foreign objects.
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.
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.
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.
Install the plug with a new gasket.

Using a voltmeter, measure the voltage between the terminals of the 2 phase connectors.
Standard voltage |
---|
0 V |
Tech Tips
Use measuring range of DC 750 V or more on the voltmeter.
DISCONNECT FRAME WIRE
CAUTION:
Wear insulating gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Disconnect the 2 harness clamps.
Remove the 4 bolts, and disconnect the frame wire (high voltage cables of the hybrid battery) from the inverter with converter assembly.
DISCONNECT GENERATOR CABLE
CAUTION:
Wear insulating gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Turn back the wire harness cover and release the cable.
Remove the 5 bolts, and disconnect the high voltage cables of the generator cable (MG1) from the inverter with converter assembly.
DISCONNECT MOTOR CABLE
CAUTION:
Wear insulating gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
Disconnect the harness clamp.
Remove the 5 bolts, and disconnect the high voltage cables of the motor cable (MG2) from the inverter with converter assembly.
DISCONNECT NO. 2 ENGINE WIRE
CAUTION:
Wear insulating gloves.
Note
Insulate the disconnected terminals with insulating tape.
Cover the hole where the cable was connected with tape or equivalent (non-residue type) to prevent entry of foreign matter.
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.
Disconnect the harness clamp.
INSTALL INVERTER COVER
Temporarily install the inverter cover with the 9 bolts to prevent any foreign objects or water from entering the inverter with converter assembly.
DISCONNECT NO. 2 ENGINE ROOM WIRE
Remove the relay block cover.
Release the 2 clamps, and remove the No. 1 relay block cover.
Remove the bolt from the No. 2 engine room wire.
Release the 2 claws, and disconnect the No. 2 engine room wire.
Connect the No. 2 engine room wire to the protector.
DISCONNECT WATER HOSE
*1 | Retainer |
Release the retainer and disconnect the water hose from the inverter with converter assembly.
*1 | Retainer |
Release the retainer and disconnect the water hose from the inverter with converter assembly.
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.
REMOVE INVERTER WITH CONVERTER ASSEMBLY
CAUTION:
Wear insulating gloves.
Remove the 3 bolts and inverter with converter assembly.
Note
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.
To prevent damage, do not hold the inverter with converter assembly by the connectors.
To prevent damage due to static electricity, do not touch the terminals of the disconnected connectors.
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.
REMOVE MOTOR CABLE BRACKET
Remove the 2 bolts and motor cable bracket.
REMOVE HIGH VOLTAGE FUSE
CAUTION:
Wear insulating gloves.
Tech Tips
Perform this procedure only when replacement of the high voltage fuse is necessary.
Remove the 9 bolts and inverter cover.
Note
Make sure to pull the inverter cover straight up, as a connector is connected to the bottom of the cover.
Remove the 2 bolts and high voltage fuse from the inverter with converter assembly.
Note
Do not allow any foreign objects or water to enter the inverter with converter assembly.
Temporarily install the inverter cover with the 9 bolts to prevent any foreign objects or water from entering the inverter with converter assembly.
REMOVE NO. 2 ENGINE ROOM WIRE
Tech Tips
Perform this procedure only when replacement of the No. 2 engine room wire is necessary.
