The Renault Master belongs to the light commercial vehicle (LCV) range. Over the years, it has been offered in various body styles, including standard and extended-wheelbase variants. Heavy-duty Master variants with higher payloads are also marketed under the Messenger and Mascott names. This model is twin-badged with the Opel Movano and Nissan Interstar, sharing an identical fuse and relay layout. The third generation was produced from 2010 through the present. Below is detailed information on the location, layout diagrams, and photographs of the fuse and relay boxes for the third-generation Renault Master (chassis codes FV, JV; X62 platform). The fuse for the “cigarette lighter” is highlighted in bold.
Because the Renault Master was manufactured over an extended period with various body configurations and electrical options, a single universal fuse and relay diagram cannot apply to all models. Please exercise caution, as the manufacturer reserves the right to make technical design changes without prior notice. Your vehicle’s actual fuse box layout may differ from the information presented here. For specific queries, contact an authorized dealer.
