Be sure to read Precaution thoroughly before servicing Click here.
INSPECT AUXILIARY BATTERY VOLTAGE
Measure the voltage between the terminals of the auxiliary battery.
Standard voltage |
---|
Approximately 11 V or more |
Tech Tips
The horn should sound clearly.
If the voltage is 10 V or less, either charge the auxiliary battery (charging usually takes about 1 hour), or replace it with an auxiliary battery that is already charged.
Check the charge level of the HV battery.
Check whether the HV battery warning message is shown in the multi-information display.
Confirm if the engine starts. If the engine starts, leave it idling with park (P) selected until the engine stops (self charge has completed).
If the engine cannot start, follow the procedure and charge the HV battery.
Tech Tips
Before performing external charging, always use the GTS to perform troubleshooting.
Charging time using the THS charger is 10 minutes per charge cycle. The charging time when using a THS charger is a short charging time (when the battery temperature is 25°C (77°F), 10 minutes may be sufficient; if the battery temperature is 0°C (32°F), then three 10 minute charge cycles may be required) for putting the engine in a condition where it can be started (the system can enter the READY-on state). (The THS charger will automatically stop 10 minutes after charging starts.)
PREPARATION FOR HV BATTERY CHARGING (for LHD)
CAUTION:
When performing work on high voltage systems, be sure to wear insulated gloves and use insulated tools.
Do not start the hybrid system with the service plug grip removed because it may cause a malfunction.
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, wait 10 minutes before touching any of the high voltage connectors or terminals.
Tech Tips
Removing the service plug grip interrupts the high voltage circuit.
High voltage wiring connectors are orange.
Remove the luggage compartment floor mat.
Remove the luggage compartment trim cover LH.
Disconnect the cable from the auxiliary battery negative (-) terminal.

Remove the inverter cover Click here.
Remove the connector cover assembly Click here.
Check the terminal voltage.
CAUTION:
Wear insulated gloves.
Note
Do not allow any foreign objects or water to enter the inverter with converter.
Using a voltmeter, measure the voltage between the terminals of the 2 phase connectors.
Standard voltage |
---|
0 V |
Tech Tips
Use a measuring range of DC 750 V or more on the voltmeter.
Remove the bolt and disconnect the No. 4 floor wire.
Note
Do not damage the terminals, connector housings or inverter with converter assembly when disconnecting them.
Do not touch the connector waterproofing rubber or terminals.
Insulate the removed terminals with insulating tape.
Do not allow any foreign objects or water to enter the inverter with converter assembly.
Measure the resistance according to the value(s) in the table below.
Tech Tips
If the shield line of the No. 4 floor wire is not securely connected to body ground, the THS charger will not operate. The "FAULT" and "CABLE CONNECTION" warning lights will illuminate on the THS charger.

HV BATTERY CHARGING (for LHD)
Turn the power switch on (IG).
Connect the GTS to the DLC3.
Enter the following menus: Powertrain / Hybrid Control / Active Test / Battery Charge.
Tech Tips
During the "Battery Charge" Active Test, check "System Main Relay Status - SMRB" and "System Main Relay Status - SMRG" in the Data List.
If the Data List values are not as specified in the table below, turn the GTS and the power switch off and then perform the Charge Battery procedure again.

Make sure that the EMERGENCY STOP switch is in the reset condition (the switch is turned clockwise and released).
Make sure that the BREAKER is in the ON position.
Turn the THS charger MAIN switch on.
Tech Tips
The MAIN indicator will illuminate in green.
Press the START switch.
Tech Tips
When the START switch is turned on, the INITIAL CHECK indicator illuminates and an initial check starts. When the initial check completes successfully, the INITIAL CHECK indicator turns off, the CHARGING indicator illuminates and charging will start at the same time.
While the INITIAL CHECK indicator is illuminated, the insulation, 400 V output, emergency stop switch, connector connections and ground connection are inspected.
Repeat the charge cycle 3 times. When the last cycle has finished, turn the THS charger MAIN switch off.
Tech Tips
Charging time using the THS charger is 10 minutes per charge cycle. The charging time when using a THS charger is a short charging time (when the battery temperature is 25°C (77°F), 10 minutes may be sufficient; if the battery temperature is 0°C (32°F), then three 10 minute charge cycles may be required) for putting the engine in a condition where it can be started (the system can enter the READY-on state). (The THS charger will automatically stop 10 minutes after charging starts.)
There is very little chance of overcharging the HV battery during the second or third charging cycle. The SOC will not likely increase beyond the upper limit because it was low enough to prevent the engine from starting. Even if the SOC was to increase enough to exceed the limit, the hybrid vehicle control ECU will stop the Active Test to prevent overcharging.
Cranking the engine once causes the SOC to drop approximately 1%.
Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.
Turn the power switch off.
Remove the THS charger and install the No. 4 floor wire.
Note
Make sure to disconnect the EV bonding cable last.
Disconnect the power inlet plug of the charger from the receptacle.
