REMOVE SERVICE PLUG GRIP
CAUTION:
Wear insulating gloves.
Remove the service plug grip to interrupt the high voltage circuit at the time of inspection or repair.
Keep the removed service plug grip in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.
All the high voltage wiring connectors are colored in orange.
Wear insulating gloves and remove the service plug grip after sliding up the lever of the service plug grip as shown in the illustration.
CAUTION:
Keep the removed service plug grip in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.
After removing the service plug grip, do not touch the high voltage connectors or terminals for 10 minutes.
Tech Tips
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
REMOVE FRONT SPOILER COVER (w/ Front Spoiler)
REMOVE ENGINE UNDER COVER
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.

Remove the bolt.
Remove the bolt, clamp and clip, and disconnect the engine room main ware.
REMOVE INVERTER TERMINAL COVER
CAUTION:
Wear insulating gloves.
Remove the 9 bolts and inverter terminal cover.
Note
Make sure to pull the inverter terminal cover straight up, as a connector is connected to the bottom of the cover.
CHECK TERMINAL VOLTAGE
CAUTION:
Wear insulating gloves.
Note
Do not allow any foreign objects or water to enter the inverter with converter assembly.
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 removed 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 frame wire (high voltage cables of the hybrid battery) from the inverter with converter assembly.
Disconnect the harness clamp.
DISCONNECT HIGH VOLTAGE CABLE OF FRONT TRANSAXLE
CAUTION:
Wear insulating gloves.
Note
Insulate the removed 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 5 bolts, and disconnect the high voltage cables of the generator (MG1) from the inverter with converter assembly.
Turn back the wire harness cover and release the cable.
Remove the 5 bolts, and disconnect the high voltage cables of the motor (MG2) from the inverter with converter assembly.
Disconnect the harness clamp.
DISCONNECT NO. 2 ENGINE WIRE
CAUTION:
Wear insulating gloves.
Note
Insulate the removed 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 TERMINAL COVER
Temporarily install the inverter terminal 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
Release the retainer and disconnect the water hose from the inverter with converter assembly.
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.
