REMOVAL
1. Precautions
After turning the ignition switch to OFF, you may have to wait for a while before disconnecting the battery terminals. Check appropriate precautions for battery terminal disconnection before proceeding. (Refer to 
)
)
2. Removal of the battery current sensor ASSY
(1) Disconnect the connector.
(2) Undo the nut and disconnect the engine wire from the battery current sensor ASSY.
CAUTION:
The power windows are equipped with an index function that is linked to the opening and closing of the doors and allows the glass to be opened and closed a little. The molding may be damaged when the doors are opened or closed after disconnecting the battery ground terminal when the glass is completely closed. Therefore, always disconnect the battery ground terminal with the driver's or passenger's seat door open (with the glass lowered to a position that allows free door opening and closing).

UNIT INSPECTION
1. Inspection of the battery current sensor ASSY
(1) Resistance check (Battery current sensor ASSY)
(a) Measure the resistance between the terminals.
