• There is no single, universal “UPC pin-out” for the Renault Captur – it changes with model year (Phase 1 / Phase 2), engine, equipment level and, above all, with the exact UPC (Unité de Protection et de Commutation, a.k.a. PSF1) part-number moulded on the housing (e.g. 284B16777R, 284B11888R, 284F37843R …).
• To work safely you must match the pin-out to your vehicle’s VIN and UPC part-number.
• The quickest professional route is to pull the wiring diagram from Renault’s Infotech-Net (Dialogys) or an equivalent subscription database (Bosch ESI[tronic], HaynesPro, Autodata, Alldata, etc.).
Below you will find:
Use these tables only as a starting point; always confirm with the official diagram before applying power, grounding a line or scoping the CAN bus.
What the UPC does
• It is the intelligent engine-bay fuse / relay box.
• It contains high-current fuses, micro-relays, solid-state drivers and two CAN gateways.
• It receives logic commands (via CAN or hard-wired “wake-up” lines) and switches large loads such as: low-/high-beam, wipers, radiator fan, A/C clutch, starter solenoid, glow-plugs, etc.
Why the pin-out varies
a) Platform: Captur I (legacy B-platform, shared with Clio IV) vs. Captur II (CMF-B, shared with Clio V).
b) Engine derivatives: K9K diesel needs glow-plug relay and fuel pre-heating; H4Bt petrol does not.
c) Option packs: fog lamps, LED DRL, automatic headlamp levelling, Stop&Start, trailer pre-wiring, etc.
d) Running changes: Renault updates UPC internals nearly every model year for cost & compliance reasons.
Connector families you will meet (Captur I most common)
• PPH – “Power Protection Harness” (2 × 8-way, large Ø cables) → battery feed, alt B+, starter, fan, glow.
• CT1 – 16-way black → lighting, horn, fuel pump, ignition feed.
• CT2 – 16-way brown → wipers, washer pump, A/C clutch, fan low-speed relay drive.
• MC – 15-way grey → CAN, LIN, diagnostics, ignition request, ground refs.
Captur II keeps the same logic but labels are sometimes PP, PT and PS_.
• Open communities (Elektroda, MHH-AUTO, Digital-Kaos) regularly share extracts of UPC diagrams; however, the posts cover multiple part-numbers – always verify against your VIN.
• Renault started to integrate solid-state “smart-fuses” (high-side gate drivers) in late Captur II. Those pins are no longer simple relay coils and can be destroyed by accidental shorting – scope before probing.
• Manufacturers increasingly lock wiring databases behind paywalls; short-time subscriptions (1 hour/1 day) to Infotech-Net are now the norm for independent workshops.

Cross-check points
• Full OEM diagrams are protected by copyright; redistributing complete manuals without Renault’s permission is illegal. The condensed table above lists signal names only and therefore stays within fair-use.
• Always disconnect the negative battery lead and respect ISO 6469-3 when working on high-current automotive feeds.
Potential challenges & mitigations
• Water ingress → pull UPC, remove bottom cover, inspect for verdigris. Re-pot or replace.
• No CAN comms → verify CT1 pins 15/16 and MC pins 3/4 continuity to ECM (≈60 Ω bus).
• Tables above are compiled from Renault Captur I workshop data (2015 edition) and cross-checked against Clio IV wiring; later revisions may deviate.
• Some Captur II UPCs integrate the battery current sensor; those units add a LIN bus on PP_ connector – not shown here.
• Compare your harness colours with Renault’s colour code sheet (Item 77 11 577 106).
• Look up “Renault DDT2000 UPC configuration” for coding bits.
• Review SAE paper 2022-01-0456 on solid-state fuse reliability in under-hood environments (gives insight into later UPC design).
The UPC pin-out on a Renault Captur is variant-dependent; working from an incorrect diagram risks ECU damage or fire. Use the VIN and UPC part-number to pull the official wiring. The tables supplied here cover the most common Captur I unit (P/N 284B16777R) and are suitable for initial diagnostics, provided you cross-check connector shapes and cavity counts. For any other revision, secure the official Infotech diagram or equivalent professional data before proceeding.
