The Chery Tiggo 8 (T18), produced from 2017 to 2020, is a mid-size SUV known for its spacious interior, modern design, and advanced features. Its electrical system, which includes the fuse box and relay components, is crucial for ensuring the vehicle’s operation and reliability.

The fuse box in the Chery Tiggo 8 (T18) from 2017 to 2020 contains various fuses designed to protect specific electrical circuits throughout the vehicle. These circuits power essential components such as the engine control module, lighting systems, infotainment features, climate control, and more. Fuses play a critical role as they interrupt the electrical flow in case of an overload or short circuit, thereby preventing damage to sensitive components.

Relays in the Chery Tiggo 8 (T18) act as electrically operated switches that control high-current circuits. They facilitate the precise activation and deactivation of functions like the starter motor, fuel pump, air conditioning compressor, and power windows or seats. Efficient management of power distribution by relays contributes significantly to the vehicle’s overall performance and reliability.

Regular inspection and maintenance of the fuse box and relays are essential to ensure the Chery Tiggo 8 (T18) from 2017 to 2020 operates smoothly. This includes checking fuses for signs of wear or damage, ensuring secure relay connections, and promptly addressing any electrical issues that arise. Proper care of these components helps maintain the vehicle’s electrical integrity, enhancing safety and driving satisfaction for owners of the Chery Tiggo 8 (T18) from 2017 to 2020.

WARNING

  • Never replace a fuse with one that has a higher amperage rating.
  • A fuse with a too-high amperage could damage the electrical part and cause a fire.
  • On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
  • If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
  • Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
