Today’s repair shops don’t get to choose what vehicles show up at their doors.
On any given day, a single bay might see a domestic SUV, a European luxury sedan, an Asian import, or a performance vehicle loaded with advanced electronics. As vehicle technology continues to evolve, that diversity is only increasing — and with it, the pressure on shops to diagnose confidently across makes and models.
For many shops, the real challenge isn’t technician skill. It’s diagnostic coverage.
Coverage gaps quietly cost shops revenue
When diagnostic tools only support certain makes or systems, shops are forced into difficult decisions:
- Juggle multiple scan tools to cover different vehicles
- Hesitate when an unfamiliar platform rolls in
- Sublet diagnostics or programming work
- Send customers to the dealer “just to be safe”
Each of these decisions carries a cost — not just in time, but in lost revenue and lost control of the repair relationship.
When a customer is sent elsewhere for diagnostics, there’s no guarantee they return for the repair. What starts as a coverage gap can quickly turn into a lost job.
Vehicle diversity is the new normal
All-makes service is no longer an exception — it’s the baseline.
Independent shops are seeing:
- More European and luxury vehicles aging into aftermarket service
- ADAS systems becoming standard across brands
- Software-driven vehicles that require coding and programming
- Platform complexity that crosses traditional brand lines
As these trends continue, diagnostic tools that only partially cover today’s vehicle mix create friction at the front counter and uncertainty in the bay.
In a modern shop, diagnostic coverage directly impacts what work you can accept.
The problem with too many tools
Many shops attempt to solve coverage gaps by adding tools. Over time, that often leads to:
- Multiple platforms with overlapping capabilities
- Inconsistent workflows between technicians
- Higher training and subscription costs
- Still not enough coverage when a new vehicle shows up
More tools don’t always mean better diagnostics. In many cases, they add complexity without eliminating the core problem.
What shops really need is confidence — the confidence that one solution can handle the majority of vehicles they see, without hesitation or handoffs.
What all-makes diagnostics should actually deliver
An effective all-makes diagnostic solution isn’t just about brand lists. It should enable shops to:
- Diagnose a wide range of vehicles using a single platform
- Access system-level insights, not just fault codes
- Handle ADAS, coding, and programming tasks with confidence
- Reduce reliance on sublets and dealer referrals
- Commit bay time knowing the diagnostic path is clear
When coverage and capability come together, shops spend less time asking “Can we diagnose this?” and more time focusing on “How quickly can we fix it?”
Keeping work in-house starts with coverage confidence
Shops don’t lose work because they lack experience — they lose it when diagnostic limitations force conservative decisions.
All-makes diagnostics help remove that hesitation by giving shops the tools and visibility they need to take on more vehicles, more consistently, without sending customers elsewhere.
Solutions like ZF MultiScan are designed to address coverage gaps by supporting diagnostics, ADAS, coding, and programming across a wide range of makes and models — all through a single platform — helping shops keep more work in-house.
The bottom line
Coverage gaps don’t always show up on a balance sheet — but their impact is real.
As vehicle diversity continues to grow, the ability to confidently diagnose across makes and models will separate shops that keep work in-house from those forced to send it away. Investing in true all-makes diagnostics isn’t about having more tools — it’s about having the right one.
