•  A current sensor has been adopted which determines the battery condition to charge the battery to the required minimum level (no excess/deficiency).

•  When installing the current sensor, connect the negative battery cable first, then install the current sensor connector. If the current sensor connector is installed first, the PCM may mistakenly recognize a signal from the current sensor, causing interference with engine control.If a DTC related to the current sensor is stored, the engine is stopped by i-stop control and a part of the generator output is inhibited as the fail-safe.

•  If a DTC is stored due to the user disconnecting/connecting the negative battery cable, clear the DTC and verify that the engine-stop by i-stop control and a part of the generator output control are restored. If a malfunction has occurred, repair the malfunction and clear the DTC, then verify that the fail-safe is finished.

•  If the user disconnects/connects the negative battery cable, the i-stop may be disabled temporarily. If the user claims that the i-stop does not operate, verify if the user disconnected/connected the negative battery cable, perform the battery condition initial setting, then tell the user that the i-stop does not operate for a while after disconnecting/connecting the negative battery cable, or ask the user to bring the vehicle to the dealer.

•  Previously, after the engine was started, power generation/discharge by the generator was performed until the battery was fully charged.
