CAUTION:
Orange wire harnesses and connectors indicate high-voltage circuits. To prevent electric shock, always follow the procedure described in the repair manual.
To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.
Note
The type of battery voltage sensor to be used varies depending on the vehicle model.
*a | Black Label |
The type of battery voltage sensor can be confirmed by the color of the label.
If the wrong type of battery voltage sensor is installed, the power switch cannot be turned on (READY).
After installing the battery voltage sensor, perform the following to check that the power switch can be turned on (READY).
Turn the power switch on (READY).
Turn the power switch off and wait for 30 seconds or more.
Turn the power switch on (READY) again.

PRECAUTION
REMOVE HV BATTERY ASSEMBLY
REMOVE UPPER HV BATTERY COVER PANEL
REMOVE NO. 2 HYBRID BATTERY SHIELD SUB-ASSEMBLY
REMOVE NO. 1 HYBRID BATTERY SHIELD SUB-ASSEMBLY
REMOVE HYBRID BATTERY TERMINAL BLOCK
REMOVE UPPER NO. 1 HYBRID BATTERY COVER SUB-ASSEMBLY
REMOVE NO. 1 HYBRID BATTERY EXHAUST DUCT
REMOVE BATTERY VOLTAGE SENSOR (for Upper Side)
CAUTION:
Be sure to wear insulated gloves and protective goggles.
High voltage is output to the battery ECU assembly from the battery voltage sensor (for Upper Side). As a result, detach the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.
Remove the 4 nuts and No. 1 HV battery protector (for upper side).
Disconnect connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit.
CAUTION:
Make sure to the disconnect the connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.
Note
Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector
Disconnect connector C on the No. 1 hybrid battery pack wire side.
CAUTION:
Make sure to the disconnect the connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.
Note
Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector
Remove the battery voltage sensor (for upper side).
Note
Do not drop the battery voltage sensor (for upper side), strike it with tools or subject it to impact.
If the battery voltage sensor (for upper side) is subjected to an impact, replace it with a new one.
