Acura TLX | 2014-2020 | Fuse Box Diagrams and Locations

In this article, we focus on the first-generation Acura TLX, a luxury sedan produced from 2014 to 2020. Combining advanced technology, a refined design, and engaging driving dynamics, the first-generation TLX was developed as a replacement for both the Acura TL and TSX models, merging their best features into a single, well-rounded offering. This model introduced a new level of sophistication and performance, quickly becoming a popular choice in the luxury sedan market.

Here, you will find detailed fuse box diagrams for Acura TLX models manufactured in 2014, 2015, 2016, 2017, 2018, 2019, and 2020. These diagrams are essential for understanding the car’s electrical systems, enabling easy identification and replacement of fuses. The article also provides comprehensive information about the locations of the fuse panels, which are typically situated in the interior cabin—usually under the dashboard—and the engine compartment. These panels are easily accessible, making maintenance and troubleshooting more convenient.

Additionally, the guide includes a thorough explanation of the fuse layout, detailing the specific functions of each fuse and relay. These assignments cover a wide range of components and systems, such as headlights, turn signals, power seats, windows, the infotainment system, air conditioning, and safety features like ABS (Anti-lock Braking System) and airbags. Relays controlling systems like the cooling fan, fuel pump, and heated mirrors are also covered.

Whether you are addressing an electrical issue, performing routine maintenance, or simply becoming familiar with your Acura TLX, this resource offers the detailed information you need to keep the vehicle’s electrical systems functioning reliably. As the first iteration of the TLX, this model set a strong foundation for Acura’s future sedans, offering a blend of comfort, technology, and performance. Understanding its fuse and relay system is a crucial step in maintaining its exceptional performance and reliability.

The fuses for the cigar lighter and power outlets in the Acura TLX are Fuse No.14 (Console Compartment Accessory Power Socket) and Fuse No.40 (Center Pocket Accessory Power Socket) located in the Interior Fuse Box Type A.
