Hazard

The connector portion branching the electrical circuit from the main harness is covered with tape. During rain or wet driving conditions, water entering from the main harness end may travel through the protective tube and seep into the connector. Accumulated water can then conduct along the wire core to the rear brake light switch. This causes switch contacts to corrode, resulting in poor electrical continuity and potential failure of the rear brake lights to illuminate during braking.

メインハーネスから電気回路を分岐させるコネクタ部がテープで覆われているため、雨天走行等でメインハーネス先端より浸入した雨水等が保護チューブ内を伝わりコネクタ部が浸水すると、溜まった水が電線内の芯線を伝わって後輪用制動灯スイッチまで達することがある。そのため、スイッチ接点が錆びて導通不良となり、後輪制動時に制動灯が点灯しなくなるおそれがある。

Remedy

All vehicles: Repair the tape covering the electrical wiring connectors and replace the rear brake light switch with a new unit.
