Fuses and relays Lexus GS300 / Toyota Aristo 147, 1991 - 1997

The first generation Lexus GS 300 is an analogue of the Toyota Aristo 147 model for the Japanese market, which, in turn, was built in 1991 on the Crown Majesta platform. The design of the car was developed by the famous Italdesign studio Giorgetto Giugiaro . As a result, the Aristo received a spectacular and quite stylish appearance, corresponding to the status of a luxury mid-size sedan. In this material, we will analyze in detail the fuse circuits of the 1st generation Toyota Aristo (147/141 body), as well as the Lexus GS 300 (S140): 1991, 1992, 1993, 1994, 1995, 1996 and 1997 release.


Here you will find the locations and photos of the fuse blocks. Separately, we note the fuse responsible for the cigarette lighter.
