Renault Trafic 3 Wiring Diagram May 2026
Document ID: RT3-WD-2025 Vehicle Generation: Renault Trafic III (2014–present), including Nissan Primastar & Fiat Talento twins. Abstract The Renault Trafic III moved from conventional relay-controlled circuits to a multiplexed BCM (UCH) architecture . This paper decodes the wiring diagram’s structure, identifies core power distribution nodes, maps the four CAN buses, and provides practical diagnostic guidelines using wiring schematics. 1. System Overview The wiring diagram is organized by power modes and functional domains:
| Domain | Control Module | Fuse Box | Wire Color Code Standard | |--------|----------------|----------|--------------------------| | BCM (UCH) | UCH (under dash) | Passenger junction box | French NFC 15-510 | | Engine bay | Fusebox | Under-hood (Maxi fuses) | DIN 72551 | | Engine ECU | EDC17C60 (diesel) | Integrated relay board | ISO 4141 | Renault Trafic 3 Wiring Diagram
CAN High wires are coded T (e.g., T, TB, TV). CAN Low = R (e.g., R, RB, RV). 5. Connector & Wire Color Code Table (French Standard) Renault uses a hybrid of French and ISO colors: TV). CAN Low = R (e.g.
