Audi A5 Training Manual – Factory SSP 395 Networking and Electronics

You want to fix an electrical gremlin on an Audi A5 without understanding how the control units talk to each other? That is how you fry a gateway module or spend half a day chasing a short that isn’t there. I’ve seen it. This Training Manual (Self-Study Programme 395) is not a repair manual – it says so right on page 3. What it does give you is the factory map of every CAN bus branch, every control unit location, and the diagnostic nodes that let you pinpoint a failure before you ever touch a multimeter. 20 pages of pure electrical architecture. Nothing else like it if you actually care about getting the job done without rework.

Before you crack open a wiring diagram or start swapping parts, you need to know where the control units live and which bus they ride. The dash panel insert – that’s the instrument cluster – talks on the suspension CAN bus. If you don’t know that, you’ll be pulling the wrong fuse block. Page 10 shows exactly where those control units sit. Page 4 lays out every fuse and relay. That kind of info keeps a diag session under an hour instead of a whole afternoon.

7 Systems Covered – CAN Bus, MOST Bus, and Beyond

This Audi A5 Training Manual breaks down the networking into digestible sections. Here is the real meat – the parts that save you from guessing:

• Fuses and relays (p. 4) – complete layout, no aftermarket guesswork
• Infotainment components (p. 6) – where the radio, amp, and Nav live
• Powertrain CAN / extended CAN (p. 8) – engine, transmission, ABS control units
• Dash panel insert / suspension CAN (p. 10) – cluster, suspension modules, sensors
• Convenience CAN (p. 12) – door modules, seat controls, sunroof
• MOST bus topology (p. 16) – fiber optic ring for audio and video
• Diagnostics (p. 19) – how to use the gateway J533 to pull DTCs and check bus health

Each section shows installation locations and CAN node connectors. For anyone who has ever tried to trace a no-start that turned out to be a corroded terminal on the convenience CAN, you know this is gold.

Does This Manual Cover the Fuel System or Engine Rebuild?

No. That is not what this is. This is a training manual – a self-study programme from Audi’s own curriculum. It teaches you the networking, not the mechanical repair. But if you are working on an A5 and the symptoms point to a network failure (intermittent lights, no crank, radio dead), this is where you start. The battery monitor control unit J367 and the onboard power supply J519 are both covered in the overview section starting on page 20. You get the pinout logic and the data bus diagnostic interface function. That is exactly what you need to decide whether to code a new battery module or cut out a bad CAN wire.

Source Validity – OEM Training, Not Aftermarket

I have seen too many aftermarket “manuals” that reprint the same generic wiring diagram for four different model years. This Audi A5 Training Manual is factory-produced by Audi Service Training. It refers to software versions valid at the time of preparation. It tells you the values are guidelines – and that is honest. For actual repair specs (torque, fluid capacities) you still need the official repair manual. But for CAN bus topology, control unit locations, and fuse assignments, this 20-page document is more accurate than any third-party product. The Audi A5 Training Manual – Factory Electronics Guide is a companion resource, and you can pair it with the Audi A5 Training Manual – Factory SSP 395 Networking and Electronics direct from this site. There is also a longer Audi A5 Training Manual (SSP 392) – 92 Pages | AutoRepairManuals if you need deep dive into mechanical systems.

3 Reasons You Need This Before Touching the Suspension CAN

First, the suspension CAN bus is not the same as the powertrain CAN. If you unplug the wrong module, you lose ride height data and trigger a Christmas tree of lights. Second, the installation locations on page 10 show where the suspension control unit J775 lives – inside the left footwell under a cover. Third, the CAN node connectors on page 18 let you verify termination and resistance without backprobing the wrong pins. I have watched a shop hand kill a gateway by jumping power to the wrong CAN-H pin. This manual prevents that.

FAQ – What Real Techs Ask About This Manual

Is this the same as the Audi A5 repair manual?

No. This is a self-study programme (SSP 395) that focuses on networking and electrical system architecture. It does not contain torque specs or step-by-step replacement procedures. Use it as a training tool to understand how the control units communicate before you crack open the repair manual.

Does it include wiring diagrams?

Not full wiring diagrams. It shows CAN bus topologies, installation locations of control units, and CAN node connectors. For actual schematic-style wiring, you need the factory repair manual. This gives you the physical layout and bus routing.

Will this help me diagnose a no-start on my 2010 A5?

If the no-start is caused by a CAN bus fault – like a shorted data line or a failed gateway – yes. The diagnostics section on page 19 explains how to interpret the data bus diagnostic interface and check bus integrity. But if the issue is mechanical (fuel pump, starter motor), you need the repair manual.

How many pages and what year is it for?

20 pages. Publication year is not printed, but this SSP 395 applies to early Audi A5 models (2007 onward) with the original electrical architecture. It covers the MOST and infotainment CAN configurations used before the MIB 2.0 update.

Bottom line – if you work on Audi A5 electrical systems and you don’t have this Training Manual in your digital library, you are working blind. I keep a copy on my shop tablet and refer to it every time a CAN-related fault comes in. For 20 pages, the density of real installation data is hard to beat. Pair it with the Automotive Industry Overview to see how OEM training differs from consumer manuals, or Automotive Industry Overview for general reference. Access the Factory Manual from AutoRepairManuals and stop guessing where that CAN wire runs.
