Filing in context
This is the only filing in the archive that cites the Drive battery control computer as the affected component. This filing is one of 38 Mitsubishi notifications from 2017 in this archive. For scale, 2,139 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 1 year and 2 months.
Defect
The cell monitor unit, which measures drive battery voltage and temperature, contains incorrectly programmed control software. When the vehicle rolls backward on an uphill start while battery voltage is temporarily fluctuating, the drive system may fail to generate propulsive force. As a result, the vehicle may be unable to move forward and may continue to roll backward down the slope.
Corrective action
On all vehicles, reprogram the cell monitor unit control software to the corrected specification.

状況
駆動用バッテリーにおいて、バッテリーの電圧や温度を測定するセルモニターユニットの制御プログラムが不適切なため、上り坂での発進時にバッテリー電圧が一時的に変動した状態で車両が後方へ下がると駆動力が発生しないことがある。そのため、発進ができず、坂道を下がるおそれがある。
改善措置
全車両、セルモニターユニットの制御プログラムを対策仕様に書き替える。
