Most electrical circuits on this French minivan are protected by fuses. High-current consumers are connected via relays. Fuses and circuit protection components are housed in distribution boxes located in the passenger compartment and under the hood.
The diagram information applies to second-generation Renault Scénic models (chassis code JM; C platform) covering model years 2003 through 2009.
