In this article, you will find information about the fuses of the Lexus CT 200H (models 2011, 2012, and 2013), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Lexus CT 200H
The fuses are designed to blow, protecting the wiring harness from damage. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Replace the blown fuse with a new fuse of an appropriate amperage rating. The amperage rating can be found on the fuse box lid.
Caution!
- Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse.
- Always use a genuine Lexus fuse or equivalent. Never replace a fuse with a wire, even as a temporary fix. This can cause extensive damage or even fire.
- Do not modify the fuses or fuse boxes.
Location of Fuse Boxes
Engine Compartment:
Push the tab in and lift the lid off.
Passenger Compartment:
Remove the lid.
Never check or replace the fuses as there are high voltage parts and wiring near the fuse box. Doing so may cause electric shock, resulting in death or serious injury.
