Jaltest, developed by Cojali in Spain, is the most comprehensive multi-brand commercial vehicle diagnostic platform in the world. It covers 241 manufacturers and over 6,750 models across heavy-duty trucks, off-highway equipment, material handling, marine, and more — all from a single interface.

Add in guided troubleshooting, wiring diagrams, technical bulletins, and continuous software updates, and you have a tool that pays for itself fast.

Jaltest covers virtually every category of commercial vehicle and heavy equipment:

• Heavy-Duty Trucks: Freightliner, Kenworth, Peterbilt, Volvo, Mack, International, Western Star, Hino, Isuzu, PACCAR, and dozens more
• Engines: Cummins, Detroit Diesel, CAT, PACCAR MX, Navistar, Mercedes-Benz
• Trailers: Wabash, Great Dane, Utility, Hyundai Translead, Carrier, Thermo King
• Off-Highway: John Deere, Caterpillar, Komatsu, Volvo CE, Case, Bobcat, Kubota
• Material Handling: Toyota, Crown, Hyster-Yale, Raymond, CLARK, Linde, Jungheinrich, and 40+ MHE brands
• Marine & Power Generation: Mercury, Yamaha, Volvo Penta, John Deere, Kohler

Visit our product pages for full coverage lists, or call us and we will confirm coverage for your specific fleet.

Jaltest software runs on a Windows-based PC or laptop. We recommend a laptop with Windows 10 or 11, at least 8 GB of RAM, and a solid-state drive for best performance. We offer complete kits that include a pre-configured Panasonic Toughbook rugged laptop — ideal for shop and field use. If you already own a compatible laptop, we can provide the Jaltest diagnostic interface and software separately. Call us and we will help you determine the best setup for your needs.

Cojali releases major Jaltest software updates quarterly, with incremental updates and coverage additions throughout the year. Each update adds new vehicle models, expanded system coverage, updated wiring diagrams, and new guided diagnostic routines. Your annual software subscription keeps you current with the latest updates. We notify customers when major updates are available and our support team is here to help with installation if needed.

Yes. Jaltest provides full aftertreatment system support including forced DPF regenerations, SCR system diagnostics, DEF quality testing, NOx sensor resets, and soot level monitoring across most supported platforms. You can initiate parked regens, monitor regen progress in real time, and diagnose aftertreatment fault codes — all from the Jaltest interface. This is one of the most-used features for fleets and independent shops dealing with emissions system issues daily.

We provide live trained-staff support — not a call center, not a chatbot. When you call 800-217-0063, you talk to experienced diesel technicians who use Jaltest every day. We help with software installation, hardware setup, diagnostic questions, troubleshooting specific vehicle issues, and anything else that comes up. We have been an authorized Jaltest dealer since 2016, and supporting our customers is what we do best.

Our support team is available Monday through Friday, 8:00 AM to 5:00 PM CST. Call us at 800-217-0063 or email support@dieseltruckdiagnostictools.com. We respond to emails within one business day. For urgent after-hours issues, send us an email and we will prioritize your request first thing the next business day.

Yes. All Jaltest diagnostic hardware comes with a manufacturer warranty from Cojali. The standard warranty covers defects in materials and workmanship. Warranty terms vary by product — interface adapters, cables, and Toughbook kits each have their own coverage period. We stand behind everything we sell. If you experience a hardware issue, contact us and we will handle the warranty process directly so you are not dealing with overseas support on your own.

That is exactly what our trained-staff support is for. If you are working on a truck and need help interpreting fault codes, running a forced regen, performing a calibration, or navigating the Jaltest software to find the right test, call us. Our technicians have decades of combined experience across all major commercial vehicle platforms. We are not just selling you a tool — we are helping you use it to fix trucks and keep your fleet moving.

We offer one-on-one remote training sessions to help you get the most out of your Jaltest system. Whether you are brand new to the platform or want to learn advanced features like guided diagnostics and wiring diagram navigation, our team can walk you through it. Training is included with your purchase — just call us to schedule a session at a time that works for you. We also provide quick-start guides and tips to help you hit the ground running.

We offer a 30-day return policy on hardware and accessories in original, unused condition with all original packaging. To initiate a return, contact us at 800-217-0063 or email support@dieseltruckdiagnostictools.com to receive a Return Merchandise Authorization (RMA) number. Returns without an RMA number cannot be accepted. Please see our Refund Policy page for complete details.

Software licenses and annual subscriptions are non-refundable once activated. Because software licenses are registered to your specific hardware and cannot be transferred or reused, we cannot accept returns on activated software. If you have questions about software licensing or want to make sure you are purchasing the right license for your needs, call us before you buy and we will help you make the right decision.

Once we receive your returned item and verify it meets our return conditions, we process your refund within 7 to 10 business days. Refunds are issued to the original payment method. You will receive an email confirmation when your refund has been processed. Please note that your bank or credit card company may take an additional 3 to 5 business days to post the refund to your account.

Yes. We offer financing options for qualified buyers on Jaltest diagnostic kits and packages. Financing allows you to spread the cost of your investment over manageable monthly payments, making it easier to equip your shop or fleet without a large upfront expense. Call us at 800-217-0063 to discuss financing options and find out if you qualify. Our team will walk you through the process and help you choose the plan that fits your budget.

Financing eligibility depends on a few factors including your business history and creditworthiness. To get started, call our team at 800-217-0063. We will ask for some basic information about your business and connect you with our financing partner. The application process is straightforward and you will typically receive a decision quickly. We work with businesses of all sizes — from independent owner-operators to large fleet operations — and we will do our best to find an option that works for you.
