Using Fuse Removal
WARNING: This page is about a different car, the 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
To clear the DTC, remove ECU-B fuse, from fuse block (located in engine compartment, near battery), for 20 seconds or longer. After reinstalling fuse, ensure only normal DTC "00" appears.
