Jaltest by Cojali
The Complete Guide
for UAE & GCC
Everything you need to know about Jaltest — the professional multi-brand diagnostic platform for commercial vehicles, trucks, buses, off-highway equipment, marine, and material handling in Dubai, Sharjah, Abu Dhabi, and across the Gulf.
If you have been searching for a professional diagnostic solution for your heavy truck, bus, construction, or marine workshop in Dubai, Sharjah, Abu Dhabi, or anywhere in the GCC, chances are you have come across the name Jaltest. This guide will explain exactly what Jaltest is, how it works, which vehicles it covers (including popular GCC brands like Freightliner, Volvo, Mercedes-Benz, Caterpillar, and Hino), and most importantly — how much it costs and where to buy it in the UAE.
AutoMax Tools (automaxtools.me) is your trusted, GCC-based supplier for Jaltest and all professional diagnostic tools. We ship to Dubai, Sharjah, Abu Dhabi, Ajman, Ras Al Khaimah, Kuwait, Saudi Arabia, Qatar, Bahrain, and Oman.
1. What is Jaltest and Why It’s the #1 CV Diagnostic Tool in the GCC?
Jaltest is a professional multi-brand diagnostic platform manufactured by Cojali, a Spanish engineering company with over 40 years of experience in vehicle electronics and diagnostics. Cojali distributes Jaltest in more than 135 countries, making it one of the most widely deployed commercial vehicle diagnostic tools on the planet.
Unlike tools that focus on a single segment (like on-highway trucks only), Jaltest covers five distinct vehicle segments: Commercial Vehicles (CV), Off-Highway (OHW), Agricultural Vehicles (AGV), Marine, and Material Handling Equipment (MHE). Each segment has its own software module and cable kit, but they all run through the same Jaltest Link V9 hardware interface and the same Jaltest Diagnostics software platform.
In the UAE market, Jaltest competes with tools like NEXIQ USB-Link 2 (paired with Noregon JPRO), Autel MaxiSYS CV, and various OEM-specific diagnostic tools. What sets Jaltest apart is the combination of multi-brand breadth with OEM-level diagnostic depth — genuine bi-directional controls, parameter adjustments, guided diagnostics, and system-specific data across all major systems.
Covers every major North American, European, and Asian commercial vehicle brand — Freightliner, Volvo, Mack, Hino, Isuzu, Mercedes-Benz, MAN, Scania, and many more.
Bi-directional controls, actuator tests, forced DPF regeneration, SCR reset, injector calibration, parameter changes, and ECU reprogramming.
Step-by-step diagnostic procedures with embedded wiring diagrams, component locations, and technical releases — all inside the software.
One tool handles Class 6-8 trucks, buses, excavators, tractors, forklifts, and marine engines through the same Jaltest Link V9 interface.
Embedded service repair information with direct links from DTC to troubleshooting guides, system checks, and maintenance schedules.
2. How Jaltest Works – Step by Step
Here is a clear walkthrough of the Jaltest diagnostic process — from connecting to the vehicle through to completing the repair verification.
Plug the Jaltest Link V9 interface into the vehicle’s diagnostic port — OBD2, 9-pin Deutsch, or manufacturer-specific connector depending on the vehicle. The V9 supports J1939, J1708, CAN, and proprietary protocols.
Open the Jaltest Diagnostics software on your Windows laptop. Select the vehicle segment: Commercial Vehicles (CV), Off-Highway (OHW), Agricultural (AGV), Marine, or Material Handling (MHE).
Jaltest can automatically detect the vehicle make, model, year, and VIN via the diagnostic bus. Alternatively, manually select from the extensive database of 214+ makes and thousands of model variants.
Read fault codes from engine, transmission, ABS, aftertreatment (DPF/SCR/DEF), body controller, instrument cluster, HVAC, and SRS systems. Jaltest provides OEM-specific codes, not just generic J1939/J1708 codes.
Click on any fault code to access Jaltest INFO Online — embedded troubleshooting guides, wiring diagrams with component locations, step-by-step repair procedures, and technical releases from Cojali.
Command outputs, run actuator tests, force DPF regeneration, perform SCR resets, adjust parameters, calibrate injectors, and run system-specific tests — all from within the software.
Clear diagnostic trouble codes after repair, verify using live data streams and system tests, and generate a report for the customer or fleet manager.
3. Jaltest 5 Vehicle Segments Explained
Jaltest is unique because one hardware platform (Jaltest Link V9) covers five completely different vehicle segments. Each segment requires its own software license, but they all share the same interface and software platform.
Class 6-8 trucks, buses, coaches, and delivery vehicles. Covers engine, transmission, ABS, aftertreatment, body controllers, instrument clusters, and HVAC. Primary segment for UAE truck and bus workshops.

5. Key Features & Capabilities
Jaltest goes far beyond reading and clearing fault codes. Here are the key capabilities that make it a professional-grade diagnostic tool for UAE workshops:
Command outputs, run actuator tests, force DPF regeneration, perform SCR resets, and run cylinder cutout tests — all from the diagnostic tool.
Change configurable ECU settings where the manufacturer allows — speed limiters, idle speed, fan control, and more.
Step-by-step troubleshooting procedures with wiring diagrams, component locations, and technical releases embedded in the software.
Real-time data streams from all vehicle systems with graphing capabilities for advanced troubleshooting and verification.
Injector calibration, ECU reprogramming (via Central Services), after-replacement configurations, and parameter coding.
Not just engine codes — full coverage of transmission, ABS, aftertreatment, body controller, instrument cluster, HVAC, and SRS systems.
Software available in multiple languages including English, Arabic, Spanish, French, German, and more — essential for UAE multicultural workshops.
Generate detailed diagnostic reports for customers, fleet managers, and warranty claims with full documentation of tests performed.
Many budget tools can pull standard J1939/J1708 fault codes from any truck with an OBD port. Jaltest goes far deeper:
- Real OEM data — not generic codes, but manufacturer-specific fault descriptions and repair procedures
- Bi-directional control — actually command the vehicle to perform tests, not just read status
- Guided diagnostics — the software tells you what to check next, not just what failed
- System coverage — diagnose the transmission, ABS, aftertreatment, and body systems, not just the engine
- Calibration capability — perform injector coding, parameter changes, and ECU updates
For a professional workshop in Dubai or Sharjah, this depth translates directly to faster diagnosis, more accurate repairs, and higher customer satisfaction.
6. Jaltest INFO Online – Repair Information
Jaltest INFO Online is Cojali’s embedded service repair information module, available as part of the Jaltest subscription. It is one of the most complete technical databases available for commercial vehicle repair in North America and is equally valuable for UAE workshops.
INFO Online includes three essential modules that make it indispensable for professional HD service repair shops:
Wiring diagrams, component locations, connector pinouts, and system technical data for every supported vehicle make and model.
Step-by-step diagnostic procedures linked directly from fault codes — no more guessing what to check next.
Manufacturer-recommended maintenance intervals, service procedures, and technical bulletins.
Cojali’s own technical releases and service bulletins addressing common issues and updated procedures.
7. Required Hardware & Setup for UAE Workshops
To use Jaltest, you need the following hardware in addition to the software license:
The latest generation hardware interface supporting J1939, J1708, CAN, and proprietary protocols. Connects to all five vehicle segments with appropriate cable kits.
Windows 10 or 11 (64-bit). Minimum 8GB RAM, SSD recommended. Panasonic Toughbook FZ-55 is the industry standard for shop and roadside use due to rugged construction and sunlight-readable display.
Segment-specific cable kits for CV, OHW, AGV, Marine, and MHE. Each kit includes OBD2, 9-pin Deutsch, and manufacturer-specific connectors.
Required for software updates, INFO Online access, and Central Services (remote ECU programming). A 4G/LTE mobile hotspot is sufficient for field use.
A 12V battery support unit is essential when performing extended diagnostic sessions or ECU programming — voltage drops can corrupt ECU data. Critical in UAE heat conditions.
Cojali provides online training videos and documentation. AutoMax Tools offers initial setup, orientation, and ongoing technical support for UAE customers in Arabic and English.
