Renault Master belongs to the light commercial vehicle (LCV) range. Over its production run, the Renault Master was offered in various body styles, including standard and extended-wheelbase variants. Heavy-duty or increased-payload variants are also branded as the Renault Messenger and Mascott. This model was rebadged as the Opel Movano and Nissan Interstar, featuring identical fuse and relay box layouts. The second-generation Renault Master was produced from 1997 to 2010, receiving a facelift (restyling) during its production lifecycle.
This guide details the locations, diagrams, and assignments of the relay and fuse boxes for the second-generation model (chassis code FD; X70 platform). The fuse for the cigarette lighter is highlighted in bold.
