Jaltest Diagnostics — Heavy Duty and Off-Highway Diagnostic System
Jaltest is the multibrand diagnostic system from the Spanish manufacturer Cojali. It is not a single tool but a system: the Jaltest Link hardware, the software modules you choose on top of it (CV, AGV, OHW, MHE, Marine), and a cable set for each module. That is why "what does Jaltest cost" has no single answer — the package is built around the vehicles you work on. This page explains how that package is put together.
In short: five vehicle segments (truck-bus-trailer, agriculture, off-highway, material handling, marine), OE-level diagnostics, Expert Mode for ECU parameter changes and DPF replacement, guided troubleshooting, wiring diagrams, maintenance data and repair times. The hardware is the Jaltest Link V9.
The System Has Three Parts
| Part | What it is | How it is chosen |
|---|---|---|
| 1 · Hardware | Jaltest Link V9 — the vehicle communication interface | One interface works with all five modules. Bought once. |
| 2 · Software module | CV · AGV · OHW · MHE · Marine | Whichever vehicle group you work on. Several can be combined. |
| 3 · Cable set | The diagnostic connectors for that segment | Varies by module; a truck cable does not fit an agricultural machine. |
On top of that sit the additional modules that deepen the work: technical information, wiring diagrams, workshop management and remote support. They are covered separately below.
Software Modules: Which Vehicle Group, Which Module?
| Module | Coverage | For whom |
|---|---|---|
| Jaltest CV | Trucks, tractor units, buses, trailers and semi-trailers, light commercial vehicles and pick-ups | Heavy-duty workshops, fleet shops, trailer service |
| Jaltest AGV | Tractors, combines, agricultural machinery and implements | Agricultural machinery dealers, cooperatives, large farms |
| Jaltest OHW | Off-highway machinery — excavators, loaders, graders, dozers, cranes | Construction and mining service shops, rental companies |
| Jaltest MHE | Material handling — forklifts, pallet trucks, warehouse equipment | Logistics centres, materials handling service |
| Jaltest Marine | Vessels — inboard and outboard engines, boat systems | Marina workshops, boat maintenance businesses |
Same hardware, different software. This is the logic of Jaltest: if you only work on trucks today you start with CV; when off-highway work arrives tomorrow you do not buy another tool — you add the OHW module and its cable set to the same Link. It makes the tool a growing investment rather than a one-off purchase.
Jaltest CV: The Most Widely Used Module
CV is the most used part, because its coverage runs from the truck to the trailer. The functions the manufacturer lists:
Guide by fault code
What the code means and what to check, in what order, step by step.
Guide by symptom
A route even with no code: a diagnostic flow that starts from "no power" or "smoking".
System technical data
Operating values and limits — how you know whether a measured value is normal.
Wiring diagrams
Model-level circuit diagrams; the part that saves the most time on a wiring fault.
Vehicle technical data
Engine, transmission and system identification.
Maintenance data
Service intervals and values.
Repair times
The standard time for each job — the basis for quoting a customer.
Releases and procedures
Manufacturer bulletins on known faults and their fixes.
Expert Mode
The most talked-about part of CV is Expert Mode. In it, ECU parameters can be changed, sensors and actuators calibrated, and the procedures required after a DPF replacement completed. Being able to do that outside a franchised dealer is work an independent workshop wins back.
FCA security gateway
On Fiat Chrysler light commercial vehicles, write operations are locked behind a security gateway. Jaltest CV performs SGW authentication on those vehicles; gateway unlocking is also offered as a separate module.
Additional Modules
| Module | What it does |
|---|---|
| Jaltest Info | Technical information and troubleshooting documentation — unit descriptions, procedures, known faults |
| Jaltest Info Plus | Info plus smart guides and model wiring diagrams |
| Jaltest Info Web | The same technical information through a browser |
| Jaltest OEM RMI | Access to the manufacturer's Repair & Maintenance Information |
| Jaltest GRP | Workshop management: work orders, customer and vehicle records, history |
| Jaltest Central Services | Exclusive diagnostic functions with remote assistance |
| Jaltest ATS | Advanced Technical Support — reaching a specialist on a job you are stuck on |
| SAT module | Additional dealer-level operations |
| SGW unlocking | Write access on security-gateway locked vehicles |
| Spare parts search | Ties parts lookup and stock into the diagnostic workflow |
| Knorr-Bremse Diagnostics | The brake manufacturer's own diagnostic tool, integrated into Jaltest |
| Data-Link RP1210 / Pass-Thru | Turns the Jaltest Link into a standard interface other software can use |
Why the Knorr-Bremse integration matters. On heavy duty, the brake system (EBS, ABS, ESP) is usually Knorr-Bremse, and those units are where general diagnostic tools struggle most. Running the manufacturer's own software from inside Jaltest means dealer-level capability on the brake side.
Jaltest Link V9 Hardware
- Maximum connection speed — faster communication than the previous generation
- USB and SubD-26 connector protection — a poka-yoke design that physically prevents plugging a cable in wrong
- Robust electronics and enhanced communication capability
- Impact absorption — protective rubber housing
- Compact and light — portable for roadside assistance
All Jaltest products are designed for workshop and roadside conditions and prepared to face extreme working and weather conditions.
Moving from V8 to V9. The V9 connector design changed. If you own cables from the previous generation, an adapter is needed to use them with the V9. Tell us what cable set you have before ordering and we will work out which adapter applies.
How the Package Is Built
- Identify the vehicle group. Truck, off-highway, tractor, forklift, vessel? It can be more than one.
- Choose the software modules. One per vehicle group; bought together they run in one interface.
- Add the cable set. Each module has its own diagnostic connectors.
- Take the hardware. The Jaltest Link V9 is shared by every module.
- Consider the additional modules. Wiring diagrams, OEM information, workshop management and technical support as needed.
- Renew the licence. The software runs on an annual licence; new models and systems arrive with updates.
Why no price on the page? Because there is no single Jaltest price: the number of modules, the cable sets, the additional modules and the licence period decide it. Tell us which vehicle groups you cover and how many users there will be, and we will send you a line-by-line quote for that configuration. Selling the wrong package serves neither of us.

What Is in the Kit
Full kit
The Link interface, multipin adapter set, cables and a rugged computer.
Hardware
Jaltest Link, the adapter set and a hard carrying case.
Software
Five modules in one interface: CV, AGV, OHW, MHE and Marine.
- Jaltest Link V9 — vehicle communication interface
- The chosen software module(s) — with the licence key
- Multipin adapter set — for the segment's diagnostic sockets
- OBD diagnostic cable
- USB cable
- SubD-26 extension cable
- Hard carrying case
- Optional: rugged tablet or laptop
Cable sets differ by segment. A heavy-duty cable set is not the same as an agricultural or marine one. Tell us which segments you will work in and we will itemise the kit.
Who It Is For
- Multibrand heavy-duty workshops — one system instead of a separate tool per make
- Fleet operators maintaining their own vehicles in-house
- Trailer and semi-trailer service — EBS and ABS diagnostics
- Agricultural and off-highway service shops — with the AGV and OHW modules
- Logistics centres — forklift and warehouse equipment with MHE
- Marina and boat workshops — with the Marine module
- Roadside assistance teams — compact hardware and guided diagnostics
Let us build the right package together. Choosing the wrong module in Jaltest means both unnecessary cost and a "this does not connect" surprise. Send us the makes and types of vehicle you work on, how many people will use it and whether you already own another diagnostic tool; we will send the configuration and the price in writing.
