BYD Fuses Guide
All vehicle circuits are provided with fuses to prevent short circuit or overloading. These fuses are mounted in the under-bonnet power distribution box (PDB) and dashboard PDBs, respectively. Fuse labels are included in these PDBs, showing the correspondence of fuses with electrical components.
- Under-hood PDB
- Dashboard PDB
- The fuses under the hood are located at the left rear part in the engine compartment. To open it, remove the trim first, and press the latch.
- The dashboard fuse under the driver’s side is located on the left side of the dashboard. Take apart the lower body of the dashboard to check the fuse.
- Replacement of blown fuses with ones of higher amperage can significantly increase the likelihood of damage to the electrical system.
- If there is no spare fuse of the same amperage, use a fuse with lower amperage instead.
REMINDER
- Do not use fuses with amperage higher than the rated ampere value or any other solution to replace the fuses, as this can cause serious damage or even a fire.
- If a fuse blows, it is recommended to check or replace the fuse at a BYD authorized dealer or service provider.

How to Replace the Fuses of the BYD SEAL
Replacing a fuse in your BYD SEAL is a straightforward process that ensures the proper functioning of your vehicle’s electrical components. Here’s a step-by-step guide to help you through the process:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Steps to Replace the Fuse:
-
Instrument Panel Fuse Box: Located under the driver’s side dashboard.
-
Engine Compartment Fuse Box: Situated on the rear left side of the motor compartment.
-
Consult the Fuse Diagram: The diagram on the fuse box cover to identify the specific fuse related to the malfunctioning component.
-
Inspect the Fuse: Use a fuse puller or a pair of needle-nose pliers to remove the suspected fuse. Hold it up to the light to check if the metal strip inside is broken.
-
Match the Fuse: Ensure the replacement fuse has the same amperage rating as the one you’re replacing. Using a fuse with a different rating can cause electrical issues or damage.
-
Insert the New Fuse: Push the new fuse firmly into the correct slot.
