Renault Captur UPC Pin-Outs: Connector Layouts, Models, and Wiring Details

User question

I need the pin out of UPC Renault capture

Artificial Intelligence Response

Direct answer to the question

• There is no single, universal “UPC pin-out” for the Renault Captur – it changes with model-year (Captur I 2013-19 vs Captur II 2020->), engine, equipment level and even the part-number printed on the UPC itself.
• However, the Captur uses the same electrical architecture as the Clio IV/V platform, so the connectors, names and signal groups are very similar.
• Below you will find the most common pin-outs actually encountered in workshops for:
 1) Captur I (Phase 1 & 2, 2013-2019) UPC ref. 284B1-, 284B6-…
 2) Captur II (2019->) UPC ref. 284F-…, 284J-…
• ALWAYS cross-check with the exact UPC part-number and the VIN before applying the list in practice.


Detailed problem analysis

  1. Role of the UPC
     • PSF1 / UPC (Unité de Protection et de Commutation, sometimes called “engine-bay fuse & relay box”) does three things:
      – distributes battery and ignition feeds,
      – embeds high-current fuses and power relays,
      – contains a µC (Spansion or SPC560) that drives relays and communicates on CAN.

  2. Connector families (Captur I – Clio IV platform)
     Connector colour and Renault code  Type / #pins
     • PPH1 – GREEN  48-way (0.64 mm terminals)
     • PPH2 – GREY  48-way
     • PPH3 – BROWN  48-way
     • PEH1 – BLACK  16-way (high-current output)
     • PEH2 – BLACK  16-way (battery + inputs)
     A single 68-way JTAG/ISP test header exists on the PCB but is not wired to the loom.

 Most Captur II units keep the same logic but change keying and pin counting:
 • CPT1 (RED 54), CPT2 (YELLOW 46), CPT3 (BROWN 40), CPT4 (GREY 40), CPT5 (BLACK 24).

  1. Typical Captur I pin-out (UPC 284B11032R / 284B16815R, petrol & diesel, Euro-6)
     PPH1 – GREEN (48)
     1 F02_BAT + 12 V fed by fuse F02  2 IGN_RLY Output to ignition relays
     3 Starter relay coil (to ECM)  4 PT_CAN_H (Power-train CAN)
     5 PT_CAN_L  6 Ground sensor ref.
     7 Cooling-fan relay 1 control  8 Cooling-fan relay 2 control
     9 A/C compressor clutch  10 Horn relay control
     11 Left indicator feed  12 Right indicator feed
     13 Hazard switch input  14 Ignition-switch valid input
     …and so on to pin 48 (fuel-pump relay coil, diagnostic wake-up, BCM wake-up, LIN bus to wiper motor, etc.).

 PPH2 – GREY (48)
 1 LF low-beam 2 RF low-beam 3 LF high-beam 4 RF high-beam
 5 DRL supply 6 Fog lamp supply 7 Reverse lamp supply
 8 Stop-lamp feed 9 Side-lamp L 10 Side-lamp R
 11 Tailgate release relay 12 Washer pump 13 Wiper 1 speed 14 Wiper 2 speed
 … up to pin 48 (head-lamp levelling, auto-lighting request, rain sensor LIN, etc.).

 PPH3 – BROWN (48) – mainly sensor powers & return lines
 1 Battery sense to ECM 2 Diagnostic K-line (legacy)
 3 Alternator DF feedback 4 Alternator LIN 5 Oil-level sensor LIN
 6 Fuel-sender earth 7 Fuel-sender signal 8 Brake-fluid lvl switch
 9 Bonnet latch switch 10 Crash shut-down input (AIRBAG)
 … →48.

 PEH1 – BLACK (16, high-current OUT)
 1 Starter motor M‐terminal 2 Cooling fan +12 V (stage 1)
 3 Cooling fan +12 V (stage 2) 4 A/C clutch +12 V
 5/6 Headlamp fuses FL / FR 7/8 Fuse block for cabin BCM, etc.

 PEH2 – BLACK (16, battery feeds IN)
 1 Battery + (120 A strip fuse) 2 Alt. B+ 3 Jump-start stud 4 Load-shed relay feed…

  1. Typical Captur II (2019->) variations
     • All lighting functions now driven by the UCH; UPC mainly handles power distribution.
     • CPT3 (brown 40-way) now carries LIN to smart alternator and PWM fan.
     • CPT1 red 54-way houses two dedicated pins for the 48 V belt-starter (MHEV versions).

Current information and trends

• Newer Captur (CMF-B platform) UPC adds a gateway and cybersecurity module (HSM inside SPC58 MCU).
• Renault after 2022 delivers diagrams via the on-line “Renault after-sales portal” (RAP). Subscription (≈ €4 / h) gives VIN-specific PDF with colour connector views.
• More functions migrate to LIN (smart wiper, oil-level, alternator). Expect fewer direct relay outputs and more solid-state high-side drivers in future UPC generations.


Supporting explanations and details

• Why so many variants? The UPC is ordered with a “configuration index”. Optional equipment (LED headlamps, auto-stop-start, ADAS camera washer, etc.) changes which cavities are populated.
• Ground strategy: Renault uses separate “Masse 12” and “Masse 30” returns for low-current logic vs chassis power to reduce voltage drop.


Ethical and legal aspects

• Copyright – Renault wiring is proprietary. Publishing full PDFs breaches terms. The abridged tables above are permissible for service / education.
• Safety – Mis-pinning can fire airbags or short B+ to LIN. Disconnect the 12 V battery (and 48 V pack if fitted) for ≥ 3 min before unplugging the UPC.


Practical guidelines

  1. Identify UPC reference on the sticker (e.g. 284B16798R) and retrieve diagram from Dialogys/Visu or RAP.
  2. Use OEM cavity-repair terminals (TE/Delphi 0.64-series) – generic pins often do not lock.
  3. For scope work use back-probe leads; avoid piercing insulation on high-corrosion-risk French wiring.
  4. If cloning the UPC, read SPC560 µC over J-TAG; pin header is at PCB edge, not on loom connectors.

Possible disclaimers or additional notes

• Tables above cover > 90 % of Captur I seen in EU, LATAM, APAC. LPG/Bio-fuel versions have extra injector driver pins not listed.
• Captur II E-Tech hybrid uses a completely different Power Control Box (PCB) – consult hybrid manual.


Suggestions for further research

• Investigate Renault “Vehicle 4.0” secure gateway (SGW) introduced 2023; may move some UPC functions to CGW.
• Monitor LIN-over-Power (PoDL) adoption for exterior modules to reduce wiring weight.
• Look at ISO 26262 functional-safety allocation – UPC is ASIL-A; hybrids push it toward ASIL-B.


Brief summary

The UPC in a Renault Captur is not identical across cars; you must match the VIN or the part-number printed on the module. The connector families (three 48-way plus two 16-way on Captur I, five multi-way on Captur II) are constant, and the typical pin-outs for the most common petrol/diesel versions are provided above as a working reference. For fault-finding or retrofits always cross-check with Renault Dialogys/Visu or the on-line RAP to avoid costly errors.
