―  PCM
―  TCM (AT)
―  Auto leveling control module (without adaptive front lighting system (AFS))

Battery Discharge Suppression Function

Note
•  This function is for suppressing battery discharge during vehicle manufacture and shipment. However, if the ROOM fuse is removed from a vehicle which has low total travel distance, the function may operate in the market.
•  The battery discharge suppression is a function in which the instrument cluster sends a battery discharge suppression signal to the start stop unit and the start stop unit suppresses the battery discharge.
•  The battery discharge suppression function operates when the total traveled distance is the threshold or less and the ROOM fuse has been removed.
•  The start stop unit switches the ignition off if 25 min have elapsed with the ignition switch in the ACC or ON position (engine off) to control the electric load.
•  When the battery discharge suppression function is operated, the instrument cluster displays [F0-002], [F0-HHH] or [F0-LLL] in the odometer/tripmeter screen of the instrument cluster to indicate that the battery discharge suppression function is operating.
•  The battery discharge suppression function is stopped under the following conditions.
―  ROOM fuse has been installed
―  Engine is started
―  Total traveled distance exceeds the threshold value
