Volvo Penta S60 2011 Wiring Diagram

If you are chasing an electrical gremlin on a 2011 Volvo S60 and you open the aftermarket diagram, you are asking for a short circuit. I have seen techs probe the wrong pin because some third-party publisher decided to simplify the drawing. That burns modules. This 300-page OEM document – TP 39203202 – is the same book Volvo dealers used when the car was new. It prints crisp on the workbench. No guesswork on wire colors. No invented connector views. You want to trace the SRS system without setting off an airbag? This is the paper you need.

Vehicles with SRS (Airbag)/SIPS bag/IC – Safety First

Page 2 of this manual spells it out: extra caution when working on SRS, SIPS, and IC components. The OCR excerpt above tells you to never pinch wires or fit accessories near the sensors. I will add this: if you puncture the SIPS bag wire harness because you thought a generic diagram was good enough, you are looking at a deployed airbag and a $3,000 repair. This manual gives you the exact routing. It also lists the explosive seat belt tensioners that were standard from 1993 onward. Know what you are grounding before you touch the steering column.

How to Use the Wiring Diagrams – Section 1:2 and 2:2

The manual starts with an explanations section that covers abbreviations and a two-part guide on reading the diagrams. Page 7 and 8 walk you through the symbols, splice locations, and how the sheets are organized. If you have ever stared at a wiring diagram that looks like spaghetti, this section will get you oriented. I recommend reading it before you touch the multimeter. The manual also includes overview pics of the electrical center and cold zone in the engine compartment – that is where most of the corrosion hides in San Antonio humidity.

Fuse and Relay Locations – Distribution Boxes in Engine, Passenger, and Cargo Compartments

Three fuse boxes. The engine compartment has fuses F1 through F38 plus the electrical center F39-F44. The Central Electronic Module (CEM) fuses F1-F24 live in the passenger compartment. Cargo compartment gets FA1-FA11. Battery fuses PF1 and PF2 are there. Relay maps cover R1-R13 in the engine bay, R1-R4 in the cabin, and RA1-RA2 at the rear. If your tail lights are dead on a 2011 S60, you check the cargo compartment first. The manual labels each fuse’s amperage and circuit – no need to guess which slot powers the headlight washer system.

Control Modules – CEM and CAN Data Communication

Three pages on the Central Electronic Module (CEM) alone. Then high-speed CAN, intermediate-speed CAN (LHD and RHD), Local CAN, LIN, and MOST bus. Each module location is diagrammed. If you are chasing a no-start related to the fuel system, you will need the engine management sections: Group 23 covers 4-Cyl. Turbo, 6-Cyl. Turbo, and 5-Cyl. Diesel EURO5 (three pages). The manual also details the Steering Wheel Module (SWM). I have seen technicians replace a CEM because they did not check the SWM ground. This book saves you that mistake.

Group 35 Lighting – High/Low Beam, Fog Lights, Tail Lights (S60 vs V60)

The lighting section separates S60 and V60 variants. High and low beam diagrams include dual-xenon versions. Beam length adjustment (manual) is covered. Running/parking lights, brake lights, reversing lights, fog lights, and follow-me-home lighting are all there. If you are installing auxiliary lights, see the related manual: Volvo S60 S60R 2007 Wiring Diagram – Section: Auxiliary Lights”>Volvo S60 S60R 2007 Wiring Diagram – Auxiliary Lights section. For beam length adjustment, the Volvo S60 2008 Wiring Diagram – Section: Beam Length Adjustment”>2008 S60 wiring diagram covers that system. The 2012 supplement has lighting updates: Volvo S60 2012 Wiring Diagram Supplement – Section: Lighting”>Volvo S60 2012 Wiring Diagram Supplement – Lighting.

Source Validity – OEM vs Aftermarket

This manual is a factory print from Volvo Car Corporation, TP 39203202. The first page states: changes up to May 2010 are included. Aftermarket publishers love to re-draw harnesses and drop ground points. I have seen schematics missing the battery PF2 fuse – that is the main feed to the cargo box. The aftermarket will tell you that is fine. It is not. The only way to be sure on a 2011 S60 is to use the OEM wiring diagram.

FAQ

Does this manual cover the airbag system?

Yes. Pages 2-3 address SRS, SIPS bag, and IC (inflatable curtain) with warnings and component identification.

Can I use this wiring diagram for a 2012 Volvo S60?

The manual covers changes up to May 2010. The 2011 model year is included, but any updates after the production date are not. Volvo service bulletins may apply for later revisions. For the 2012 model, refer to the specific supplement instead of relying on this 2011 edition. The supplement adds new lighting circuits and CAN bus updates that are absent from this 300-page document. I would not cross-reference a 2012 harness without the supplement on the bench.

You need the wire colors, the pinouts, and the ground points that match your car on the lift. Aftermarket printouts will get you cussing. Get the factory document that Volvo designed for the technician. Access the Factory Manual.
