|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 22, 2018 |
| Manufacturer(s) | Honda |
| Component | Computer (Powertrain) |
| Production period | March 2017 — July 11, 2018 |
| Vehicles affected | 1,254 units |
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。
