Hazard

The transmission electrical wiring has improper routing design, causing the connector sealing section to deteriorate over time due to heat from the exhaust manifold and rainwater exposure. This compromises seal integrity, allowing water ingress into the connector, which can cause short circuits resulting in battery discharge during parking. In severe cases, heat generated by the short circuit may melt surrounding components, potentially leading to fire.

トランスミッションの電気配線において、配索設計が不適切なためコネクタ配線のシール部が排気管の熱と雨水等により使用過程で劣化することがある。そのため、シール性能が保てずコネクタに雨水等が浸入することで短絡が発生し、駐車中にバッテリ上がりが発生することがある。最悪の場合、短絡により発熱することで、周囲の部品を溶損させて火災に至るおそれがある。

Remedy

Replace the connector at the affected location with an extended single wire on all vehicles and reroute accordingly.
