REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed or replaced during HV supply stack sub-assembly removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed
Auxiliary battery terminal is disconnected/reconnected	Perform steering sensor zero point calibration	Lane Tracing Assist System
		Pre-collision System
		Lighting System (w/ AFS)(EXT)
	Memorize steering angle neutral point	Parking Assist Monitor System
	Memorize steering angle neutral point	Panoramic View Monitor System
Replacement of No. 1 HV supply stack sub-assembly Replacement of No. 2 HV supply stack sub-assembly	Battery status info update Prediagnostic battery charge Battery diagnosis	HV battery status information cannot be updated
Replacement of battery ECU assembly Replacement of HV battery junction block assembly	Current sensor offset learning	DTCs are stored
Replacement of hybrid battery terminal block	Perform high voltage fuse accumulated load history reset	DTCs are stored

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.
The hybrid system has high-voltage circuits. Accidents, such as electric shock, or electric leaks may result if the hybrid system is not operated in a correct manner. Make sure to follow the correct procedure.
When disposing of an HV battery or HV supply stack sub-assembly, make sure to return them through an authorized collection agent who is capable of handling them safely.
Before returning an HV battery, make sure to perform a recovery inspection.
Before returning an HV supply stack sub-assembly, make sure to perform a recovery inspection.
Make a note of the output DTCs as some of them may be necessary for "Recovery Inspection" of the HV battery and HV supply stack sub-assemblies.

NOTICE:

When replacing the No. 1 HV supply stack sub-assembly or No. 2 HV supply stack sub-assembly, it is necessary to check, adjust and equalize the SOC of the HV battery. Otherwise, the engine may run longer than normal, resulting in a decrease in fuel efficiency.
