TEXA released the IDC6 Truck 2026.22 software update on November 10, 2026. It updates 37 brands in the main truck diagnostic system and 8 brands in the North America heavy duty system, and adds 145 new dashboards, 7 new wiring diagrams and 44 new technical sheets. The work covers industrial vehicles, light commercial vehicles and buses. Here is what 2026.22 means for heavy duty shops and fleets.
North America heavy duty: 8 brands updated
The Heavy Duty Diagnostic System (North America) update in 2026.22 covers Dennis Eagle, Ford, Hino, Kenworth, Mack, Peterbilt, Prevost and Wrightbus. For fleets, municipal shops and DOT garages, the familiar names here are Kenworth, Peterbilt, Mack, Ford and Hino, and Prevost matters to anyone maintaining coaches.
This release follows two weeks after Truck 2026.21, which updated Freightliner, International, Kenworth, Peterbilt, Pierce, Sterling, Thomas Built and Western Star in the same North America system. TEXA puts out truck updates about twice a month, so coverage keeps building as long as your subscription stays current.
The highlights in Truck 2026.22
TEXA called out three items in the 2026.22 release notes:
- Hino: developed the new Lane Departure Warning System (LDWS) and Radar Sensor System
- Scania: updated the S6 Engine Management System (EMS) diesel injection system
- Iveco: developed the new Telma (IRCS) retarder system
The Hino item stands out because it adds driver assistance systems, lane departure warning and radar, to the software. As more trucks arrive with these systems, shops need a tool that can talk to them after windshield, bumper or sensor work. The Scania and Iveco items are a reminder that IDC6 Truck is a global platform, and fleets that run imported or specialty vehicles benefit from that reach.
Main truck system: 37 brands updated
The main Truck Diagnostic System update covers these makes, as listed in the release notes:
- North American trucks and coaches: Ford, Hino, International, Kenworth, Mack, Peterbilt and Prevost
- Light commercial vehicles: Citroen, Fiat Professional, Nissan, Opel, Peugeot and Volkswagen
- European and Asian trucks and buses: DAF, DAF (LATAM), Dennis Eagle, Isuzu (Domestic), Iveco, Iveco (LATAM), Iveco Bus, Karsan, MAN, Mercedes-Benz, Mercedes-Benz (LATAM / Asia Pacific), Renault Trucks, Renault Trucks (LATAM), Scania, Scania (LATAM), Setra, Temsa, UD Trucks (Nissan Diesel), Volvo Bus, Volvo Trucks, Volvo Trucks (LATAM) and Wrightbus
- Engines and systems: FPT Engine and Wabco
TEXA counts regional versions such as Volvo Trucks (LATAM) as their own entries, which is how the list reaches 37.
145 new dashboards, plus wiring diagrams and technical sheets
The headline number in 2026.22 is 145 new dashboards covering live data, adjustments, settings and system scanning, compared with 16 in the last release. TEXA also added 7 new wiring diagrams and 44 new technical sheets, so more of the repair information your techs need sits inside the same software they use to diagnose.
