Volvo Penta S60 2009 Wiring Diagram – Factory OEM Specs

You’ve been burned by aftermarket wiring diagrams before. They show pins that don’t exist, leave out ground locations, or skip the SRS/airbag precautions. Then you’re stuck chasing a short with a test light and a bad attitude. This 2009 Volvo Penta S60 wiring diagram is the real deal—OEM Volvo Car Corporation publication TP 39130202. 225 pages of factory schematics, not a third-party redraw. It tells you exactly where every wire goes, what color it is, and what fuse feeds it. That includes the SRS (airbag) system, which is where most guys get in trouble. Ignore the yellow tape and you’ll be buying a new steering wheel module.

Why the OEM Wiring Diagram Beats Aftermarket Copies

Aftermarket wiring books save money by skipping the ground connection tables and control module pinouts. This manual has 22 pages of ground connections (31/1 through 31/120) and separate chapters for every control module: CEM, REM, DEM, AEM. The high-speed CAN bus and low-speed CAN bus are drawn with termination resistor values. Need to know which wire in the engine harness carries the low-speed CAN? It’s in the high-speed CAN data communication section. No guessing, no generic diagram that fits ten models. This is TP 39130202—the same book the Volvo dealer techs used until they switched to VIDA. I’ve got a 20-year-old paper copy of one of these in my toolbox. It saved me a tow-truck call more than once.

SRS and Airbag: Where the Manual Saves Your Stickers (and Your Face)

Every wiring diagram warns you about SRS, but this one dedicates two full pages to the specific precautions for the SIPS bag and Inflatable Curtain (IC). Page 2 says: “Make sure that no wires are pinched, frayed, or pierced. Never fit accessories by the sensors.” It even tells you where the SRS decals are located. If you’re swapping a steering column or replacing a seat belt tensioner, you need the ground procedure from VIDA—but the wiring diagram shows you which circuits are hot at all times. I’ve seen a tech set off a passenger airbag with a test light probe. That’s a $1,500 mistake. This manual won’t let you do that.

Engine Management System – 5-Cylinder Diesel and Gas Coverage

Group 23 covers the fuel system: engine management for 5-cylinder gas, turbo, bi-fuel, and diesel versions. Each one gets its own set of schematic sheets (e.g., 5-Cyl. Diesel 1:3 through 3:3). The cooling fan circuit and glow plug relay are separate diagrams. If you’re chasing a no-start on a 2009 S60 diesel, the diesel-specific starting system is in Group 33. The cruise control for diesel is in Group 27. This is not a generic “engine management” diagram. It’s specific to the 5-cylinder D5. You need the charge pressure sensor signal? It’s on the page that says “Engine management system, 5-Cyl. Diesel 2:3”. That’s the kind of specificity that cuts diagnosis time in half.

Electrical Distribution: Fuses, Relays, and Grounds

Eight pages of fuse maps: engine compartment (11A, 11B), passenger compartment (11C, 11O), cargo compartment (11E, 11L). Then the Central Electronic Module (CEM) fuses F1–F34 and Rear Electronic Module (REM) fuses F1–F38. Relays are listed by location codes like FMA1 and FST3. Ground connections are numbered 31/1 through 31/120. Ever had a flickering interior light that turned out to be a corroded ground at 31/67? This book shows you exactly where that ground bolt is. Aftermarket diagrams give you a generic ground symbol; this one gives you the location in the vehicle. Pair it with a Automotive Wiring reference for connector pinouts, and you’re set.

7 Electrical Groups You’ll Actually Use on the Bench

The manual covers 7 major groups beyond the essentials: lighting (Group 35), additional electrical equipment (Group 36), wiring and fuses (Group 37), instruments (Group 38), audio/nav (Group 39), transmission (Group 43), and brake system (Group 59). That means ABS diagnostics, BCM pinouts, and the shift lock circuit for the AW55-51SN transmission are all in here. If you’re retrofitting auxiliary lights, you want the Volvo S60 S60R 2007 Wiring Diagram – Section: Auxiliary Lights supplement, but this base diagram covers the factory wiring that feeds them.

Does It Cover the SRS System and Airbag Wiring?

Yes. That’s one of the first things I check on a used wiring diagram. The TOC explicitly says “Vehicles with SRS (Airbag)/SIPS bag/IC (Inflatable curtain)”. The manual includes warnings, test terminal locations, and the fusible link for the SRS system. If you’re working on a 2009 Volvo Penta S60, you need to disable the SRS per the instructions on page 2 before touching any wiring near the steering wheel or seats. The manual tells you how to recognize if the vehicle has SIPS bags (decals on windshield and seat compartment) and what to do if it has explosive seat belt tensioners.

How to Use This Manual – Quick Navigation

The Table of Contents (pages 1:2 and 2:2) lists every group. Start with “How to use the wiring diagrams” (page 6) if you’re not familiar with Volvo’s color codes and connector numbering. Then find your system by group number. For the engine, go to Group 23. For the alternator, Group 32. For the audio system with external amplifier, Group 39. The Volvo S60 2012 Wiring Diagram Supplement – Section: Lighting and VOLVO S60 2011 Wiring Diagram are separate supplements if you need later model year changes. This 2009 manual covers all changes up to May 2008; later updates are in service bulletins.

Can I use this for a Volvo Penta marine engine?

This manual is for the Volvo S60 passenger car, not a marine engine. The 2009 model year applies to the car chassis. If you need a Volvo Penta marine wiring diagram, look for the correct engine model.

What torque specs are listed in the wiring diagram?

Wiring diagrams don’t list fastener torque, but the manual includes terminal tightening torque for battery connections and ground studs. For engine mechanical torque, you need the separate service manual. The wiring diagram focuses on wire routing, connector pinouts, and fuse ratings—not bolt torque. That’s by design.

If you’re tired of squinting at blurry PDF copies of aftermarket diagrams that claim to be “OEM compatible” but leave out the SRS warnings, this is the real 225-page factory document. It comes as a searchable PDF that you can print at full size. Use it on the bench, tape it to the wall, or load it on your tablet. Access the Factory Manual and get the correct wiring colors and pin assignments for every connector on the 2009 Volvo Penta S60.
