Jeremy M. Posted November 20, 2021 Share Posted November 20, 2021 If you enter your model year on https://drivers.lexus.com/lexusdrivers/resources/owners-manuals?type=om you can pull up the owner's manual for your car, if you don't already have a physical copy. If you use the online version, which is free, go to the "electrical components" link for the PDF with fuse diagrams. There's going to be two fuse boxes, the one that has the ECU fuses is in the driver's footwell, to the left of the steering column. The fuses themselves should be covered by a small pop-off plastic cover, which will also have a labeled diagram for the fuses. Below highlighted in red are the two that deal with ECU functions Quote Link to comment Share on other sites More sharing options...
