Filing in context
The Computer (Powertrain) is the most frequently cited component category in this archive, appearing in 15 of its 4,890 filings. This filing is one of 21 Honda notifications from 2018 in this archive. For scale, 2,669 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 4 months.
Defect
On vehicles equipped with a 6-speed DCT automatic transmission, the engine control unit (ECU) that governs gear shifting is improperly positioned. Repeated low-speed driving over extended periods causes heat from the engine to raise the internal resistance of components inside the ECU. This reduces the supply voltage to the inner shaft sensor and outer shaft sensor, triggering the warning light and preventing gear shifts. In the worst case, the clutch disengages, drive force is lost, and the vehicle becomes inoperable.
Corrective action
On all vehicles, add a sub-harness and reroute the power supply voltage circuit to the shaft sensors. Replace the inner shaft sensor and outer shaft sensor as part of the circuit modification.

状況
６速ＤＣＴ型自動変速機を搭載した車両において、変速を制御するエンジン制御コンピュータ（ＥＣＵ）の配置が不適切なため、長時間の低速走行を繰り返すと、エンジンの熱影響によりＥＣＵ内部素子の抵抗値が高くなることがある。そのため、インナシャフトセンサ及びアウタシャフトセンサへ供給する電源電圧が低下し、警告灯が点灯するとともに、変速ができなくなり、最悪の場合、クラッチが切れ、駆動力が伝わらなくなり、走行不能となるおそれがある。
改善措置
全車両、サブハーネスを追加し、シャフトセンサへ供給する電源電圧回路を変更する。また、電源電圧回路の変更に伴い、インナシャフトセンサ及びアウタシャフトセンサを交換する。
