Jaltest Truck Diagnostics — Every Major Make Covered

If you work on Class 3 through Class 8 commercial trucks, Jaltest gives you a single diagnostic platform that covers every major North American and European manufacturer — plus the Asian and specialty brands that are increasingly common in mixed fleets. One tool, one interface, one set of cables, and full OEM-level access to every electronic system on the truck.

That is not marketing language. Jaltest truck coverage spans 32+ manufacturers, hundreds of model variants, and thousands of electronic control modules. From a 2008 Freightliner Cascadia with a Detroit DD15 to a 2026 Kenworth T680 with a PACCAR MX-13 and Bendix Wingman Fusion, the coverage is there.

North American Brand Coverage — In Depth

Most shops in the U.S. and Canada see the same seven brands rolling through their bays week after week. Here is what Jaltest covers for each one:

Freightliner

Jaltest provides full diagnostic access to the Freightliner Cascadia, M2 106/112, 122SD, 114SD, and legacy Columbia and Century models. Coverage includes Detroit DD13, DD15, and DD16 engine ECMs with injector coding, DPF regeneration, and SCR diagnostics. The DT12 automated transmission gets full clutch calibration and adaptation support. Bendix and WABCO ABS/stability systems, Freightliner body controllers, HVAC modules, and instrument clusters are all accessible with bi-directional control.

Kenworth

Kenworth coverage spans the full lineup from the T270 medium-duty through the W990 heavy-haul. Jaltest reads all PACCAR proprietary modules including the PACCAR MX-11 and MX-13 engine ECMs, plus Cummins X15 and ISX options. Full parameter programming access covers speed limiters, idle shutdown, PTO configuration, and engine protection settings. Eaton Endurant and Fuller transmissions, Bendix ABS and Wingman Fusion, and all chassis and body modules are included.

Peterbilt

Peterbilt coverage mirrors the Kenworth platform with model-specific calibrations for the 579, 389, 567, 520, and vocational models. PACCAR MX engine diagnostics, Cummins engine support, and all shared PACCAR platform electronics (body controller, instrument cluster, HVAC) are fully accessible. Jaltest supports both current-generation and legacy Peterbilt models back through the mid-2000s, covering the full range of engines and transmissions installed across the lineup.

Mack

Jaltest covers the Mack Anthem, Pinnacle, Granite, LR (refuse), MD (medium-duty), and TerraPro vocational platforms. Full access to the Mack MP7 and MP8 engines (based on the Volvo D11 and D13 platform), including aftertreatment system diagnostics, injector calibration, and turbo actuator testing. The mDRIVE automated manual transmission gets clutch calibration, shift adaptation, and fault diagnostics. Volvo Group shared electronics — including I-Shift variants, instrument clusters, and VMAC modules — are supported.

Volvo Trucks

Volvo VNL, VNR, VNX, and VHD models are covered with full access to the D11, D13, and D16 engine ECMs. Jaltest handles I-Shift transmission calibrations, Volvo EMS (engine management) parameter programming, aftertreatment system service (DPF regen, SCR diagnostics, DEF dosing), and all body and chassis electronics. European models (FH, FM, FMX, FE, FL) are also covered, making Jaltest a global Volvo diagnostic solution for shops that see both domestic and import units.

International / Navistar

International coverage includes the LT, RH, HV, HX, MV, and legacy ProStar, LoneStar, WorkStar, and DuraStar platforms. Jaltest accesses the Navistar A26 engine ECM plus legacy N9, N13, and MaxxForce engines. Cummins-powered International trucks are also covered through the Cummins engine module. The Diamond Logic body controller, which controls much of International proprietary wiring and accessory circuits, is fully accessible for diagnostics and configuration.

Western Star

Western Star 4700, 4900, 5700XE, and the new 49X and 47X platforms are covered with full access to Detroit DD engines, Allison and Eaton transmissions, and Bendix braking systems. Western Star shares significant electronics with the Freightliner platform under the Daimler Trucks umbrella, and Jaltest covers those shared modules seamlessly. Vocational configurations — including mixer, dump, heavy-haul, and logging specs — are supported with PTO and auxiliary system diagnostics.

Complete Diagnostic Capabilities for Trucks

Jaltest is not a code reader. It is a full-depth diagnostic platform that gives you the same functional access as the OEM dealer tool. Here is what you can do on every supported truck:

Engine Diagnostics

• PTO — power take-off engagement, speed configuration, and fault diagnostics for vocational applications
• Telematics — OEM telematics module diagnostics, connectivity testing
• Auxiliary heating — Webasto and Eberspacher fuel-fired heater diagnostics, glow plug testing, and timer programming

Gas, Diesel, and Electric Coverage

The trucking industry is diversifying its powertrains, and Jaltest is keeping pace. While diesel remains the backbone of Class 6-8 operations, Jaltest also covers:

• Gasoline/CNG engines — medium-duty trucks with gas and compressed natural gas powertrains, including Cummins ISL-G and proprietary OEM gas engines
• Battery-electric platforms — BYD electric trucks, Freightliner eCascadia, Volvo VNR Electric, Mercedes eActros, and Mitsubishi Fuso eCanter. Coverage includes battery management systems, electric drive motor diagnostics, inverter/charger modules, and thermal management systems
• Hybrid systems — Eaton hybrid systems and OEM mild-hybrid configurations with regenerative braking diagnostics

Electric truck adoption is accelerating in port drayage, regional delivery, and urban distribution. Having a diagnostic tool that already covers these platforms means your shop is ready when the first electric unit shows up on your lot — no scrambling for a new tool or a dealer appointment.

Why One Tool Beats a Toolbox Full of Brand-Specific Software

Here is the reality for most multi-brand truck shops: you have Cummins INSITE for engine work, maybe DDDL for Detroit, a separate Bendix ACom license for ABS, possibly an Allison DOC for transmissions, and a brand-specific laptop for whatever OEM tool the truck manufacturer provides. That is four to six separate software subscriptions, each with its own annual renewal fee, its own hardware requirements, and its own learning curve for your technicians.

Jaltest replaces the entire stack. Your technician connects to the truck once, Jaltest auto-detects every module on the J1939 and J1708 data buses, and presents a unified diagnostic view across all systems. No switching laptops. No wondering which tool handles the body controller. No paying five subscription renewals when one covers everything.

The cost comparison is not even close for a busy multi-brand shop. A single Jaltest truck license costs less per year than most shops spend on Cummins INSITE and DDDL combined — and Jaltest also covers the transmissions, braking systems, body modules, and every other electronic system on the vehicle.

Communication Protocols and Connectivity

Jaltest connects to trucks through the standard SAE J1939/J1708 diagnostic connector (9-pin Deutsch or 6-pin Deutsch, depending on age) and communicates on all protocols present on the vehicle network. Modern trucks use J1939 CAN bus as the primary diagnostic protocol, but older trucks (pre-2007) may still use J1708/J1587 serial communication. Many trucks run both protocols simultaneously, and Jaltest reads them all.

The Jaltest Link hardware interface supports J1939 CAN (250k and 500k baud), J1708/J1587, ISO 15765 (CAN-based diagnostics), and ISO 14229 UDS (Unified Diagnostic Services). This means Jaltest is not limited to heavy-duty truck protocols — it also communicates with medium-duty platforms that use light-vehicle-style CAN protocols, and with newer electric trucks that use UDS for battery and motor controller diagnostics.

For shops working on both North American and European trucks, Jaltest also supports the European truck diagnostic connector pinouts and protocols, so you do not need separate interface hardware for a Scania or MAN that comes through your bay.

Updates Three Times Per Year

Jaltest releases three major software updates annually, each adding new model year coverage, new diagnostic functions, additional wiring diagrams, and expanded technical data. When a new truck model hits the road — like the Kenworth W990 or the Western Star 49X — Jaltest engineering adds coverage within the first or second release cycle. You are not waiting years for new model support the way you might with some aftermarket tools.

Each update also improves existing coverage. New actuator commands, additional ECU parameter access, corrected wiring diagrams, and expanded guided diagnostic procedures are added continuously based on feedback from the 60,000+ Jaltest users worldwide and Cojali direct engineering relationships with component manufacturers like Allison, Bendix, Cummins, and ZF.

Who Needs Jaltest Truck Diagnostics

• Independent diesel repair shops — if you work on more than one truck brand, Jaltest eliminates the multi-tool headache and lets your techs focus on fixing trucks instead of managing software
• Fleet maintenance operations — whether you run 10 trucks or 500, having one diagnostic platform across your entire fleet reduces training time, simplifies inventory, and speeds up diagnosis
• Dealership service departments — Jaltest supplements your OEM tool by providing coverage for trade-ins, customer vehicles from other brands, and component systems (Allison, Bendix, Eaton) that the OEM tool may not cover deeply
• Mobile diesel mechanics — one laptop, one tool, one set of cables covers every truck you will encounter on a service call. No carrying five laptops in your van
• Vocational truck specialists — refuse, concrete, utility, heavy-haul, and other vocational applications often have unique PTO, hydraulic, and body configurations that Jaltest covers
