Where is the Vios fog light relay located?
2 Answers
Vios fog light relay is located inside the fuse box in the engine compartment. The relay, also known as an electrical relay, is an electronic control device that consists of a control system and a controlled system. It is commonly used in automatic control circuits, essentially functioning as an automatic switch that uses a smaller current to control a larger one. The Vios is an entry-level family car specifically designed and developed by Toyota for the Asian market. Based on the NBC platform with an extended wheelbase, the Vios developed on this compact car platform nearly reaches the level of a compact sedan. The dimensions of this car are 4420mm in length, 1700mm in width, 1490mm in height, with a wheelbase of 2550mm.
Last time I helped a friend fix the Vios fog light issue, I located the relay position. It's inside the fuse box in the engine compartment, usually near the battery or headlight assembly. You'll need to pop the hood and look for a small black box labeled 'FOG LAMP RELAY' with stickers or symbols. The location may vary slightly by model year - for instance, the 2015 version is on the right side while the 2018 model has it relocated. Always check the owner's manual first to avoid electrical hazards. If the relay fails, the fog lights won't work. When replacing it yourself, opt for genuine parts for better durability. I've seen many cases where oxidized relay contacts caused circuit shorting - extra caution is needed. Always disconnect the negative terminal before inspection for safety, and keep tools dry to prevent accidents. If you can't locate it, check online forum diagrams or visit the dealership directly.
