TEXA USA announced the IDC6 OHW 2026.20 software update for off-highway equipment on October 14, 2026. It updates 23 brands and adds 11 new dashboards, 14 new wiring diagrams and 27 new technical sheets across agricultural equipment, forklifts, telehandlers, construction machines and special vehicles. Here is what 2026.20 adds and where it helps in the shop.
The highlights in OHW 2026.20
TEXA called out three items in the 2026.20 release notes.
John Deere and John Deere (Brazil): EPC Power Quad / AutoQuad Plus

TEXA updated the HANSA excavator model.
Case IH and New Holland
TEXA updated the Case IH and New Holland brands. The release notes do not break this item down further, so check the coverage section on the TEXA website for your specific machines.
All 23 brands updated in 2026.20
TEXA updated diagnostic systems for these makes, as listed in the release notes:
- Agricultural: Case IH, Fendt, John Deere, John Deere (Brazil) and New Holland

TEXA counts regional versions such as John Deere (Brazil) as their own entries, which is how the list reaches 23.
Dashboards, wiring diagrams and technical sheets
The 11 new dashboards cover live data, adjustments, settings and system scanning. The 14 new wiring diagrams and 27 new technical sheets put more repair information inside the same software, so your techs spend less time looking for it and more time on the repair. For full model detail, TEXA points customers to its diagnostic coverage pages at texausa.com/coverage.
