Filing in context
The Engine Control Computer is the most frequently cited component category in this archive, appearing in 18 of its 4,890 filings. This filing is one of 31 Honda notifications from 2014 in this archive. For scale, 358 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 7 months.
Defect
The engine control unit (ECU) program is incorrect, causing wheel speed data to be stored incorrectly. The ECU may falsely determine that the vehicle is traveling on a slippery surface. This causes engine speed to rise slightly during driving and applies excessive load to the drive pulley shaft. If the vehicle continues to be operated in this condition, in the worst case the shaft may fracture, rendering the vehicle inoperable.
Corrective action
On all vehicles, reprogram the engine control unit with the corrected software.

状況
エンジン制御コンピュータ（ＥＣＵ）のプログラムが不適切なため、車輪速データを正しく記憶せず、滑り易い路面を走行していると誤判定することがある。そのため、走行中にエンジン回転が僅かに上昇するとともに、ドライブプーリシャフトに高い負荷が加わり、そのままの状態で使用を続けると、最悪の場合、シャフトが折損し走行不能となるおそれがある。
改善措置
全車両、エンジン制御コンピュータを対策プログラムに書き換える。
