DAF XF105 2005 Diagnostics Manual – Factory Fault-Code and Troubleshooting Guide

You pull a code off an XF105 – dash lights up like a Christmas tree, transmission won’t shift, EBS warning flashing. You reach for a manual and get a generic list of P-codes that don’t match the actual DAF systems. That’s lost time on a truck that should be back on the road. I’ve been there. That’s why I only trust factory documentation. DAF XF105 2005 Diagnostics Manual gives you the actual fault tables, stored in the OEM format. Not a reprint. Not a third-party summary. Original DAF data, 284 pages, covering every electronic system on this truck.

This is the same document DAF dealers used in 2005 to diagnose system faults. It’s not a repair manual – it’s a dedicated diagnostics information system and component guide. You get the structured troubleshooting tables ( storingstabel ) and the fault code explanations ( foutcodes ) for AS Tronic, EBS-2, CAN topology, EAS, immobiliser, ALS-S, CDS-3, bodybuilder module (BBM), ZF Intarder EST 42, steering, brakes, DMCI, VIC-2, driven axles, suspension, ECAS-4, MTCO, DTCO, MX-motor, steering wheel switches, transmission, power supply, lighting, ATC, air conditioning, airbag-2, and phone interface. That’s twenty-plus system groups. Each section starts with an introduction – Inleiding – then goes straight into the diagnostic steps.

AS Tronic and EBS-2 Fault Tables – What You Get

The two biggest headache systems on this truck are the automated transmission (AS Tronic) and the electronic braking system (EBS-2). This manual devotes separate chapters to each. Page references aren’t printed on every table, but you’ll find the Storingstabel AS Tronic and Foutcodes AS Tronic sections with numbered fault codes and the corresponding corrective actions. For EBS-2, the manual includes a dedicated pressure regulation table for failure modes – EBS-drukregeling bij EBS-storing. If you’ve ever chased an intermittent brake pressure fault, you know how valuable that table is.

Transmission issues on the XF105 often come down to the AS Tronic control unit or the pneumatic shift assist. The fault code explanations in this manual tell you exactly what condition triggered the code, not just the generic OBD meaning. That’s the difference between guessing and fixing.

Why Does the CAN Topology Section Matter?

Modern truck electronics run on CAN bus networks. This manual dedicates two full tables to the CAN network: one according to ISO 11898 (the standard for high-speed CAN) and one according to ISO 11992/1 (truck-specific trailer communication). When you get a CAN error that shuts down the drivetrain, you need to know which wire pair to check and what the expected resistance values are. The manual gives you the topology, not just a wiring diagram. If you’re not familiar with On-board Diagnostics (OBD) protocols, this section brings you up to speed with the truck-specific version.

I’ve had junior techs waste a whole day because they didn’t understand that a broken termination resistor in the CAN backbone looks like a sensor fault. This manual’s CAN topology tables would have saved them four hours of diag time.

284 Pages of Factory Troubleshooting Data

Two hundred eighty-four pages – that’s the thickness of a real dealer binder. Not a thin booklet. Not a pirated scan. The PDF is the original 2005 DAF publication with the copyright stamp: 200538 DW332467. You’re buying the same content that cost DAF thousands of man-hours to write and validate. Every page is laid out with the same Inleiding, Storingstabel, and Foutcodes structure. No ads, no fluff, no commentary from people who’ve never turned a wrench.

For example, the MX-motor section covers the cooling system, lubrication system, intake/exhaust, and fuel system – each with its own stored fault table. The fuel system is split into engine functions and vehicle functions, so you can separate an injector driver fault from a low-pressure supply issue. Want the air conditioning diagnosis? There’s a control table for system pressures and another for line temperatures. That kind of detail only comes from the factory.

Use the Storingstabel Before You Swap Parts

Here’s the rule: if the truck has a stored fault code, you don’t replace anything until you’ve gone through the corresponding Storingstabel. This manual lists the possible causes in order of likelihood and the checks you run before condemning a component. It saves you from the classic mistake – replacing a DMCI display because the driver says the dash shows garbled text, when the real issue is a CAN line short on the trailer connector. I’ve seen it happen. The VIC-2 section has a dedicated fault table for that exact scenario.

Brakes are another critical area. The manual includes separate storingstabels for the disc brake construction, S-cam drum brakes, and Z-cam drum brakes. If you’re getting an ABS fault, you need to know which wheel-end architecture you’re dealing with. The manual tells you the diagnostic path for each type. Don’t trust aftermarket brake diagnosis – I’ve seen those manuals skip the mechanical inspection steps that are mandatory for safety.

MX-Motor: Covers Fuel, Cooling, and Exhaust Systems

The MX engine is the heart of the XF105, and this manual treats it with the attention it deserves. The fuel system section alone has separate fault tables for engine functions and vehicle functions. That means you can isolate a high-pressure pump fault from a supply pump issue. The cooling system section includes the full storingstabel for thermostats, water pump, and fan drive. The intake/exhaust section covers EGR and turbocharger faults. If you’re chasing an engine derate, this is where you start.

One thing I appreciate about the factory approach: they always include the Inleiding (introduction) for each system, which explains the architecture in plain language. For a DIY owner who’s comfortable with heavy trucks, that introduction alone is worth the price. You don’t need to be a certified tech to follow it, but you do need to be methodical.

Audience Fit – Who Needs This Manual?

This manual is for anyone working on a DAF XF105 from model year 2005 onward. It assumes you have basic diagnostic tools (multimeter, CAN reader, laptop with DAVIE or similar software) and the ability to follow a logical troubleshooting tree. If you’re a home mechanic with a farm or small fleet, you can use this to avoid dealer labor rates. If you’re a shop owner, put this on the tech’s workstation next to the DAF XF105 Electrical system Wiring Diagram. The wiring diagram manual plus this diagnostics manual covers 95% of the electrical and electronic faults you’ll see.

Beginners should start with the AS Tronic or EBS-2 sections because those have the clearest Storingstabel layout. Read the introduction first – don’t skip to the codes. The manual is written in Dutch, but the tables use universal symbols and diagnostic flow logic. If you can read a schematic, you can work through it. For English resources, pair it with the DAF LF CF XF105 2011 Bodybuilder Guidelines (English section) and the DAF LF, CF and XF105 2010 Bodybuilder Guidelines – Section: Reaction Form for body builder interface info.

Source Validity – Why OEM Beats Aftermarket

I’ve thrown away more aftermarket manuals than I’ve kept. They use generic fault codes, guess torque specs, and often copy errors from earlier pirated versions. This manual is an original DAF factory document – the same one that shipped to dealers in 2005. The copyright page says it explicitly: DAF Trucks N.V., Eindhoven, Netherlands. It’s not a reprint, it’s not a copied PDF from a forum. The 284 pages are scanned from the original binder. That means the torque values, resistance ranges, and pressure specs are the ones DAF used at the factory. For a Manual Transmission fault, the spec for the shift fork position is the one DAF built the gearbox around. Trust that.

Frequently Asked Questions

Is this manual in English or Dutch?

The manual is entirely in Dutch. But the fault tables and storingstabellen use pictograms, symbols, and structured diagnostic logic that is easy to follow if you have basic knowledge of truck systems. If you need an English translation, you will have to work with a translator or rely on the universal OBD code structures.

Does this cover the 2006 XF105?

Yes, the 2005 edition applies to the XF105 series from 2005 onward, including early 2006 models. DAF did not change the electronic architecture significantly until the Euro 6 update.

Can I use this manual to repair the MX engine mechanically?

No, this is a diagnostics manual, not a repair manual. It covers fault codes and troubleshooting steps for engine-related electrical and electronic systems. For mechanical overhaul specs (piston ring gaps, bearing clearances), you need the workshop manual. This manual tells you how to identify why the engine is derated – not how to rebuild it.

What tools do I need to use this manual effectively?

You need a multimeter, a CAN bus diagnostic tool, and a DAF-specific software interface (DAVIE) for reading advanced fault codes. The manual lists the required checks for each fault, and many require measuring voltage or resistance on the CAN lines.

You’ve got a truck that’s down. The aftermarket forums are full of guesses. You need the actual diagnostic pathways that DAF engineers designed. Access the Factory Manual and start working through the storingstabel. The first time you fix an intermittent EBS pressure fault in twenty minutes instead of two hours, you’ll know why I recommend this document.
