Filing in context
The Computer is the most frequently cited component category in this archive, appearing in 42 of its 4,890 filings. This filing is one of 21 Nissan notifications from 2023 in this archive. For scale, 2,350 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 6 months.
Defect
The Power Network Separate (PNS) relay, which controls circuit connection between the 12V main battery and the 12V sub-battery, was developed with insufficient evaluation of the control program's behavior during power supply voltage fluctuations. When the vehicle is powered on while the 12V battery voltage is low, the PNS relay may switch off and interrupt power supply to the 12V sub-battery. If the vehicle is driven in this condition, the sub-battery voltage drops, causing warning lights on the combination meter to illuminate. In the worst case, once the vehicle is stopped, it may be unable to return to the READY ON state.
Corrective action
On all vehicles, reprogram the Power Network Separate relay control software.

状況
１２Ｖバッテリから１２Ｖサブバッテリ間の回路接続制御を行っているパワーネットワークセパレート（ＰＮＳ）リレーにおいて、開発時に電源電圧変動時の制御プログラムにおける評価が不十分であったため、１２Ｖバッテリの電圧が低い状態でパワーオンすると、ＰＮＳリレーがオフとなり、１２Ｖサブバッテリへの電源が供給されなくなることがある。そのため、その状態で走行を継続すると１２Ｖサブバッテリの電圧が低下する事によりコンビネーションメータ警告灯が点灯し、最終的には一度車両を停止させると再度ＲＥＡＤＹ ＯＮ出来なくなるおそれがある。
改善措置
全車両、パワーネットワークセパレートリレーの制御プログラムを修正する。
