Fendt Farmer 400, Favorit 700, Favorit 900, 700 Vario, 800 Vario 2007 Training Manual

You’ve got a Vario tractor that’s throwing a code, and the aftermarket scan tool gives you garbage like “generic CAN bus error.” That’s because those tools don’t have the factory fault code tables. This Fendt Farmer 400, Favorit 700, Favorit 900, 700 Vario, 800 Vario 2007 Training Manual is the exact binder that Fendt service trainers used in 2007. It’s 201 pages of nothing but fault code tables – COM I, COM II, and COM III – for the Vario range. No fluff, no reprints, no generic translations. If you’ve ever spent an afternoon chasing a phantom transmission fault, you know why this matters.

Fault Code Tables – What’s Actually In This 201-Page Manual

Every page is a fault code breakdown: ID code, brief description, consequences, and FENDIAS notes. For example, code 0.0.12 (A008) is a Vario terminal bus fault. The manual tells you the power supply is on circuit board A013, fuse F039/F046. That’s not a guess – that’s a factory spec. The manual covers the Farmer 400, Favorit 700, Favorit 900, and the 700 Vario and 800 Vario. It also includes the COM III variants for 300, 400, 700, 800, and 900 Vario. So if you’re working on a 2007 Fendt with COM III, you’ve got the table for it.

Does It Cover the 300 Vario COM III?

Yes. The table of contents lists a separate fault code table for the FENDT 300 Vario COM III. That’s a common oversight in aftermarket manuals – they skip the smaller Vario models. This is an OEM document, so it covers the entire family. The manual was produced by AGCO GmbH, Fendt’s own training division, in September 2007. The document number is PSD – 3289 G – en. If you need to verify authenticity, that’s the number.

3 Systems That Will Lock You Out Without These Codes

First: the CAN bus. Code 0.0.12 kills the Vario terminal. Without the correct fuse map (F039, F046), you’ll replace a terminal board for nothing. Second: the control console bus fault (0.0.13) takes out the entire display. Third: the transmission control unit bus fault (0.0.14) leaves you with no display and no functions. Each code has a link to the specific circuit board and fuse. That’s the difference between a ten-minute fix and a whole afternoon pulling harnesses.

Why OEM Documentation Beats a Third-Party Scan Tool

Third-party tools give you a code number and a generic description – “engine ECU fault.” This manual gives you the exact bus path, the power supply board, and the fuse numbers. It also tells you whether the tractor can still be driven (e.g., code 0.0.11 – EDC/EMR bus fault – lets you drive with accelerator only). That kind of operational guidance comes straight from Fendt’s service engineers. You can cross-reference with general Manual Transmission knowledge if you’re working on a gearbox issue, but for the Vario driveline, stick to factory data.

Get the Right Diagnostic Tools First

Before you open the manual, you need a multimeter that reads CAN bus signals and a set of Fendt-specific breakout boxes. The manual references FENDIAS software – that’s Fendt’s own diagnostic suite. If you don’t have it, you can still use the fault consequences to narrow down the problem. For example, code 0.0.11 says “programming errors in ECU” – that means a reflash, not a part replacement. The manual saves you from ordering a $3,000 ECU when a simple reprogramming is the fix. Safety warning: always disconnect battery negative before probing CAN lines. A backfeed can fry the terminal board.

Real-World Use: Fendt 800 Vario Bus Fault

I had a 2007 Fendt 800 Vario come in last month – no display, no response from controls. Pulled up code 0.0.12 from this manual. It pointed straight to fuse F046 on circuit board A013. Fifteen minutes later, the tractor was running. Without the manual, I’d have spent two hours chasing grounds. That’s the difference between a flat-rate tech who makes money and one who loses it. The manual also covers the Farmer 400 and Favorit 700/900 – same bus architecture, same troubleshooting logic.

Will this manual work for a 2005 Favorit 700?

It covers the Favorit 700, but the fault code tables are for the COM I/II/III systems introduced around 2006. For a 2005, check if your tractor has COM I or older electronics – it may not apply.

What if I have a COM III system – is it covered?

Yes. The manual has a dedicated fault code table for COM III on the FENDT 400/700/800/900 Vario. Also covered: 300 Vario COM III. You’re good.

Is this a service manual or a training manual?

It’s a training manual – focused on fault codes and diagnostics. It does not contain step-by-step engine rebuilds or wiring diagrams for the whole tractor. It’s a supplement for troubleshooting electronic systems.

Can I use this manual without FENDIAS software?

Yes. The fault code tables give you the code, the description, and the consequences independent of FENDIAS. You can read the codes from the dash or a generic scan tool and then cross-reference in this manual.
