Checking and Replacing Fuses

The fuses are designed to blow, protecting the wiring harness and electrical systems from damage. If any of the electrical components do not operate, a fuse may have melted. If this happens, check and replace the fuses as necessary. Look carefully at the fuse. If the thin wire inside is broken, the fuse has blown. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good.

In case if you do not have a spare fuse, in an emergency you can pull out fuses, which may be dispensable for normal driving (for example, audio system, cigarette lighter, OBD, seat heater, and the like), and use it if its amperage rating is the same. If you cannot use one of the same amperage, use one lower than, but as close as possible to, the amperage. If the amperage is lower than that specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clips.

Notice

  • Always switch off the ignition system and the affected electrical circuit before replacing a fuse.
  • Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse, even as a temporary fix. This can cause extensive damage or even fire.
  • If the replaced fuse blows again, have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
