Jaltest Data-Link (VCI) Interface
The Jaltest Data-Link is the diagnostic communication interface that connects your laptop to the vehicle or equipment. It supports CAN bus, J1939, J1708, K-line, OBD-II, and manufacturer-specific protocols through a single compact device. Available as a standalone purchase for shops that need a replacement unit, a second interface for another diagnostic station, or an upgrade from an older Data-Link model.

Why Diesel Truck Diagnostic Tools
You have options when purchasing Jaltest diagnostic tools. Here is what sets Diesel Truck Diagnostic Tools apart:
Authorized Since 2016
Over 17 years as an authorized Jaltest/Cojali dealer. We are not a marketplace reseller or a side business. Diesel diagnostics is all we do, and Jaltest is our primary platform. This experience means we can answer questions that other sellers cannot, troubleshoot issues other dealers escalate, and provide the kind of support that only comes from years of hands-on product knowledge.
Real People, Real Support
When you call 800-217-0063, you reach a trained staff. Not a call center. Not a voicemail tree. A person who knows Jaltest, knows the equipment you service, and can help you solve problems in real time. This is the number one reason our customers choose us over other Jaltest dealers.
Complete Product Knowledge
We carry every Jaltest product. We know which cables work with which models, which software module covers which manufacturers, and which kit configuration makes sense for your specific operation. We have answered thousands of pre-sale and technical support questions over the years, and that accumulated knowledge benefits every customer.
Fair Pricing, No Games
Our pricing is competitive and transparent. We do not inflate prices to make "sale" discounts look bigger. We do not offer gray-market products at suspiciously low prices. We sell genuine, authorized Jaltest products at fair prices with full warranty and support backing.
Financing Available
Professional diagnostic tools are a significant investment -- typically $3,000 to $15,000+ depending on the configuration. If you prefer to spread that investment over time, financing options are available. Contact us at 800-217-0063 or support@dieseltruckdiagnostictools.com to discuss financing for your purchase.
