Jaltest Industrial Vehicle 2007 Training Manual

I’ve been turning wrenches for 28 years, and I can tell you the fastest way to blow a weekend (or a customer’s ECU) is guessing which pin is power and which is ground on a heavy truck diagnostic connector. This Jaltest Industrial Vehicle 2007 Training Manual is exactly what you need if you work on any of the big European makes. It’s 51 pages of nothing but connector locations, pin assignments, and OEM-specific notes for the diagnostic ports. No fluff, no reprints – just the original 2007 Cojali document.

Connector Locations for DAF and ERF

DAF trucks from the LF up through XF105 are covered starting on page 2. If you’ve ever had to crawl under a CF85 to find the 9-pin Deutsch connector, you’ll appreciate the diagrams. ERF is on page 6 – same deal, factory connector layouts. I’ve seen too many techs fry a $600 ECU because they guessed the pinout. This manual gives you the exact pin numbers and wire colors. No guessing.

What Does This Manual Cover for MAN TG Series?

MAN TG Series trucks – that’s TG-A, TGA, and others – are in section IV.2 starting on page 17. The manual shows you where the diagnostic socket lives on these cabs and how to interface with the Jaltest software. For the older F/M/U 90 models (page 16), the connector is under the passenger seat. I’ve pulled that cover off dozens of times; having the factory diagram saves you from stripping the plastic clips.

7 Major Brands Covered

This isn’t a one-brand manual. You get OEM connector data for DAF, ERF, Iveco, MAN, Mercedes-Benz, Renault, Scania, and Volvo. Plus a section on trailers (section IX). That’s every brand you’re likely to see in a North American fleet that runs European iron. The Iveco section alone covers Eurocargo (page 7), Eurostar (page 9), Eurotech (page 11), Eurotrakker (page 13), and Stralis (page 15). Each one has its own connector variant – the manual tells you which adapter cable to use.

Identify the Correct Connector Before You Probe

One mistake I see junior techs make: they assume every 14-pin round connector is wired the same. Wrong. The Mercedes-Benz Actros MPII (page 22) uses a different pinout than the ATEGO OBD (page 23). You backprobe the wrong pin and you’ll blow the K-line driver. The manual lists the pin functions for each model year. Use a multimeter to verify continuity before you connect – the manual gives you the wire colors to test.

IVECO Eurocargo: Connector Pinout Details

On page 7, the Eurocargo connector is documented with a table showing pin 1 = battery positive (30), pin 2 = ground (31), pin 3 = K-line, pin 4 = L-line, etc. If you’re using a Jaltest kit, you need to match those pins to the correct adapter. The manual also indicates which models use CAN bus (ISO 11898) versus older ISO 9141. That matters when you’re troubleshooting a no-communication fault.

Source Validity – Original 2007 OEM Document

This is the real deal – published by Cojali S.L. in January 2007. It’s not a third-party rehash. I’ve seen aftermarket connector guides that mix up pin 1 and pin 2 on Volvo trucks; this manual has the factory-approved assignments. The copyright page (page 3) states the document is proprietary and subject to modification without notice – that’s standard OEM language. You get the original PDF, not a scanned photocopy.

Who Needs This Manual

If you work on heavy trucks in a shop or on the road, and you use Jaltest software or any diagnostic tool that needs the connector pinout, this manual pays for itself the first time you avoid a short circuit. Home garage enthusiasts who take on fleet repairs will also benefit – the manual uses simple schematic symbols, no advanced electronics theory required. You just need a multimeter and the mechanical sense to access the connector.

FAQ

Does this manual cover diagnostic procedures or only connector pinouts?

It’s strictly a connector guide – pin assignments, locations, and adapter information. No step‑by‑step diagnostic routines. That’s a separate Jaltest software feature.

My Actros is a 2004 model – will the connector information match?

The manual covers Mercedes-Benz models before 1996 (page 19), Actros (page 20), ATEGO/AXOR (page 21), Actros MPII (page 22), and ATEGO OBD/AXOR OBD (page 23). For a 2004 Actros, you’d use the Actros section (page 20) which documents the 14‑pin circular connector. If your truck has a newer OBD connector, check the ATEGO OBD page – many Actros after 2003 use the same interface as ATEGO. Verify with the year-specific notes in the manual.

If you work on any of these trucks, getting the wrong connector pinout can cost you hours. This is the factory reference. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or printed in the toolbox. I’ve got mine bookmarked.
