Filing in context
The Engine Control Unit (Computer) is the most frequently cited component category in this archive, appearing in 3 of its 4,890 filings. This filing is one of 14 Subaru notifications from 2019 in this archive. For scale, 360 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 2 years and 5 months.
Defect
The engine control unit software contains an error in the engine shutdown control logic, causing excessive current to flow through the ignition coils after the engine stops. This raises the internal temperature of the ignition coils, resulting in a short circuit and blown fuse. In the worst case, the engine may stall while the vehicle is in motion.
Corrective action
On all vehicles, inspect the ignition coils and reprogram the engine control unit with the corrected software. If an ignition coil shows damage, replace it with a new unit.

状況
エンジンコントロールユニットの制御プログラムにおいて、エンジンが停止する際の制御が不適切なため、イグニッションコイルへ必要以上に通電することがある。そのため、イグニッションコイルの内部温度が上昇し回路がショート、ヒューズ切れを起こし、最悪の場合、走行中エンジンが停止するおそれがある。
改善措置
全車両、イグニッションコイルを点検しエンジンコントロールユニットの制御プログラムを対策プログラムに書き換える。イグニッションコイルに損傷がある場合は、イグニッションコイルを新品に交換する。
