DAF 22313 Diagnostics Manual

You get a truck in the bay throwing a U010000 code. Tech pulls out his phone, Googles “U010000 DAF,” gets three different answers from forum posts. Then he starts swapping parts. That’s billable hours down the drain and a pissed-off customer. I’ve seen it a hundred times. The DAF 22313 Diagnostics Manual stops that nonsense cold. It’s the factory file – 83 pages of what the OEM actually uses when they build these trucks. Not some aftermarket translation. Not a reprint of a reprint. Real data.

What This 83-Page DAF 22313 Diagnostics Manual Actually Contains

Open the PDF and you’re looking at a table. Not a story. A table. Every active fault code the ACM, ECM, and other controllers can throw. Each row gives you: Node, DTC ISO, FailureEvent, FTB_Name, FunctBehaviorDesc, PossibleRootCause, Procedure Erase Confirmed, Proposed WorkshopAction, ProprietaryName. That’s it. No fluff. You want to know why the retarder brake is acting up? Page 3 shows ACM U001088 – lost communication on Medium Speed CAN. The proposed action: “Check: Lost communication on Medium Speed CAN Communication Bus. If fault not detected: Fault trace according to Tech Tool fault tree.” Direct. Actionable. No theory.

DTC Decoding: From Code to Root Cause

Take P054401 – Exhaust Gas Temperature Sensor Bank 1 Sensor 1. The manual doesn’t guess. It gives you the voltage thresholds: above 2.260742V and below 4.852295V, or above 0.147705V and below 0.677490V. That’s the specific window for a wiring, sensor, or ECU fault. No generic “check sensor” crap. You get the actual numbers. Then the workshop action tells you exactly what to check. If you need to understand how an On-board Diagnostics (OBD) system logs these events, the manual puts the pieces together.

Bus Off? The Manual Tells You Where to Start

ACM U000188 – “It has not been possible to send frames on High Speed CAN Communication Bus” – “Bus off”. The PossibleRootCause is simple: lost communication. The workshop action says “Check: Lost communication on High Speed CAN Communication Bus If fault not detected: Fault trace according to Tech Tool fault tree.” That’s it. No three-page essay on CAN bus theory. You check the wiring, you check the terminations, you trace it. This is the kind of direct instruction that keeps a tech from chasing ghosts.

Why Factory Diagnostics Matter Over a Generic Scan Tool

Generic scan tools give you a code and a vague description. “P205A01 – Reductant Tank Temperature Sensor.” That’s it. The factory manual gives you the specific voltage conditions that caused the fault – voltage on A:18 above 4.794922V and below 4.852295V. It gives you the exact wiring pinouts, the failure behavior (Regeneration not possible), and the three possible root causes in priority order. You can’t get that from an aftermarket database. This manual is the OEM’s own diagnostic logic. If you’re working on a truck with a Manual Transmission, you still need this to isolate engine and aftertreatment communication faults that affect drivability.

Audience – Who Needs This on the Bench?

DIY guys with a DAF 22313 in their barn? You. Professional flat-rate tech who bills by the code? Definitely you. Shop owner tired of warranty comebacks from guessed repairs? Buy it for every tech. This manual is for anyone who genuinely diagnoses faults instead of throwing parts. If you’re the kind of person who skips reading the manual and just clears codes, save your money. This one requires you to actually follow a procedure.

Does this manual include wiring diagrams?

Not for every system. It’s a diagnostics manual, meaning it focuses on DTC tables and fault-finding procedures. Wiring diagrams are referenced in the workshop actions (e.g., “Check: Lost communication on High Speed CAN Communication Bus” implies you consult the wiring diagram), but the full diagrams are in the service manual. This manual gives you the codes and root causes so you know exactly where to look.

How do I use the DTC table effectively?

Start by identifying the node that logged the code (ACM, ECM, etc.). Then locate the DTC ISO in the table. Read the FailureEvent and FunctBehaviorDesc to understand what the systems reports under failure. Check the PossibleRootCause – it lists the three most likely causes (wiring, sensor, ECU) in order. Then follow the Proposed WorkshopAction exactly. If the action says “Fault trace according to Tech Tool fault tree,” you need the Tech Tool. Most actions include specific voltage thresholds – use those to confirm the failure condition before replacement.
