We make complex products
easier to build, service and own.
Tweddle Group creates the technical content, diagnostics, parts catalogs and portals that OEMs, their service networks and their customers rely on every day.




















































The product suite built for service operations
Connected products built on your engineering data, so the fix in the bay, the part in the catalog and the answer in the cabin always agree.
Troubleshooter
Guided repair, from symptom to fix. Diagnostics built on decades of OEM engineering data that get smarter with every job across the network.
- VIN/PIN-specific guidance, not generic trees
- First-time fix rates up, comebacks down
- Support calls down 30% in year one, 9% more each year after

Tracer™
Patented electrical diagnostics for the factory floor. Interactive schematics validate harness installations and pinpoint wiring faults at the point of manufacture, deployed globally with the largest OEMs.
- Purpose-built for high volume assembly lines
- One-click circuit tracing and 2D harness views from 3D CAD
- Faults caught before they ship, rework and warranty down

Tracer-X
Interactive wiring navigation that pinpoints the most probable failure point in VIN-specific wiring networks, down to the individual connector pin.
- Trace any circuit across systems in seconds
- Multiple views, pin-to-pin accuracy
- Native Troubleshooter integration, diagnosis to wiring in one click

Electronic Parts Catalog
A parts system that synchronizes itself. Full ERP/PLM integration keeps the catalog current with engineering. No manual intervention, no stale part numbers.
- Auto-updates in the face of engineering change
- Fewer wrong-part orders, faster lookups
- Spare parts revenue, unblocked
Concept-T
Structured technical documentation without the enterprise overhead. Author, manage and publish service content in weeks, not months, built for manufacturers who have outgrown PDFs.
- Structured authoring without DITA or XML expertise
- One source published to web, mobile, PDF and print
- VIN-aware delivery, multilingual
AVA · Advanced Vehicle Assistant
An in-cabin, AI-enabled assistant that answers owner questions from your own verified content, with CAN bus integration and real-time OEM alerts. Support that never opens a ticket.
- Answers grounded in owner information, not the open internet
- Multi-channel across cabin, mobile and portal
- Stronger brand loyalty, friction-free post-sale
OI & Service Portals
Branded portals for both sides of ownership. Technicians search every content type in plain language, buy or download what they need, and owners get their exact vehicle's manuals, maintenance and recalls on any device.
- Role-based views for techs, parts staff and dealer principals
- Multimodal AI search across manuals, TSBs, wiring and video
- Manuals available to subscribe, purchase or download
- Owners see their exact vehicle, recalls and service history
Software is half the story
Four service lines carry the other half, from authoring to the glovebox.
An award-winning alternative to stand-alone creative agencies. CGI/CAD, video and design teams inside your product information partner.
Explore Creative ServicesBetter information pays for itself on the first visit
Fixed right on the first visit
VIN/PIN-specific technician support changes the unit economics of every repair order.
Owners who stay owners
Buyers judge the product by the ownership experience. Consistent, on-demand information keeps them loyal.

Fix what’s costing you most
Cars, combines or conveyor systems, you already know which of these is yours.
My service operation is backed up
Technician shortage meets rising product complexity. Guided diagnostics and wiring navigation lift first-time fix rates with the techs you already have, consistent across every rooftop.
Fix service throughput → 02Electrical faults are slowing my line
Wiring complexity is exploding in production. Patented assembly line diagnostics validate harnesses and catch faults at the point of manufacture, before they ship.
Fix it on the line → 03My content is inconsistent everywhere
Manuals, portal, call center and cabin each tell a different story. Consolidate on author-once/publish-everywhere with AI integrity checks.
Unify my content → 04I'm launching without an info strategy
We've taken products from zero to market-ready compliance before a single unit was manufactured. Launch with the information layer already built.
Launch ready →Proof, not promises
Call volumes down 30% in year one, still falling
A leading compact equipment manufacturer deployed guided diagnostics across its dealer network. Support calls fell 30% in year one and kept falling 9% a year, with 88% dealer penetration across North America.
