Dealer-Level Diesel Diagnostics · Canada
Dealer-Level Diesel Engine Diagnostic Software
Every unplanned breakdown costs you more than the repair: dealer callout fees, DPF faults you can't force-regen in the field, and sitting on hold while a truck idles in the yard — the real expense is the time lost. Jaltest diesel diagnostics gives professional shops and fleet operations the same diagnostic depth as an OEM dealer, for every brand in your yard.
Jaltest Diesel Engine Diagnostic Coverage
What Diesel Engines Does Jaltest Cover?
Most single-brand tools lock you into one ecosystem. Jaltest doesn't. Whether your fleet runs Cummins on the highway, Detroit Diesel under a highway tractor, or a mix of platforms across your yard, Jaltest covers the full range — engine ECU and aftertreatment ECU both included. That means you're not just reading codes; you have access to the full diagnostic system on both the engine and its emissions control hardware.
Cummins
ISX, ISB, ISC, ISL, ISM, X15, B6.7, and more — engine and aftertreatment ECU access.
Detroit Diesel
DD13, DD15, DD16, Series 60, and more — full ECU and SCR/DPF system coverage.
Volvo
D13, D11, D16, and much more — including aftertreatment and parameter access
PACCAR
Typically found in Kenworth & Peterbilt trucks. MX-13, MX-11, and much more — engine and emissions ECU support.
Mack
MP8, MP7, MP10, and more — full diagnostic capability including regen and actuator tests.
And Beyond
Coverage extends to construction, agricultural, marine, and off-highway diesel engines across dozens of OEMs. Check full coverage here.
Most fleets have multiple brands and models. A diesel diagnostic tool that only speaks to one brand leaves noticeable gaps in your coverage — and these gaps cost money. With Jaltest, a single license covers the trucks, equipment, and specialty vehicles in your operation.

What Dealer-Level Diesel Engine Diagnostics Actually Means
Let's be direct: reading a fault code is not diagnosing a diesel engine. Any generic OBD scanner can pull a code. What separates dealer-grade diesel diagnostic software from a consumer scan tool is what you can actually do after you read it.
Live Data Streams: Monitor boost pressure, EGR position, DEF quality, DPF soot load, injector timing, and dozens of real-time parameters simultaneously — exactly what a dealer technician sees at their workstation.
Forced DPF Regeneration: Initiate a stationary or active DPF regen directly from the tool. No waiting for the engine to decide. This alone saves hours of downtime per truck per incident for many fleets.
Actuator & Component Tests: Command individual actuators — EGR valves, injectors, cooling fans, fuel pumps — and verify mechanical response without disassembly. Isolate the fault before you pull anything.
ECU Calibration & Parameter Programming: Adjust engine parameters, reset service reminders, and perform calibrations that require OEM-level access. This is the tier where most aftermarket diesel diagnostic scanners stop.
Expert Mode: Jaltest's Expert Mode provides guided diagnostic trees developed from OEM repair data — not generic flowcharts. It helps your techs reach the right diagnosis faster, especially on complex emissions-related faults.
Multi-System Access: Engine is one system. Jaltest also communicates with transmission, brakes (ABS/EBS), chassis electronics, body control modules, and more — all through the same interface.
When it comes to capability, this is dealer-level diesel diagnostics. Your shop or fleet maintenance team works with the same depth of access as the OEM service center down the road. The difference is you control the timeline.

The Real Cost of Outsourcing Diesel Engine Diagnostics
Most fleet managers underestimate what they're actually spending on external diagnostics. They see the individual invoices…a dealer visit here…a callout fee there…but don't add it up across a year. When they do, the total cost can be alarming.
30 hrs
per month in downtime
That same operation logged over 30 hours per month in wait-related downtime: trucks sitting while they waited for a dealer tech to arrive, or waiting on a diagnostic appointment slot.
$100K+
per year in dealer call-out costs
One fleet operation tracked their dealer callout costs over 12 months before switching to Jaltest. The total, diagnostic fees, travel charges, after-hours premiums, exceeded $100,000.
Those numbers aren't unusual. Dealer callout diagnostics are expensive by design — the OEM knows you have nowhere else to turn. In-house diesel diagnostics change that math entirely. With Jaltest’s diesel diagnostic tool, your technician can perform a forced DPF regen, read live data, and run actuator tests without calling anyone, your trucks stay moving.
The shift from outsourced to in-house diagnostics isn't just about saving money on individual callouts. It's about reclaiming control over your maintenance workflow, your scheduling, and your costs.

Jaltest vs. One Brand Diesel Diagnostic Tools
Tools like Cummins Insite and JPro are purpose-built for their branded systems, and they do that well. But if your shop services more than one brand, or your fleet runs anything other than a single OEM, single-brand diesel diagnostic software creates gaps you fill with expensive dealer callouts.
| Feature | Jaltest (via WholeFleet) | Cummins Insite | JPro / Noregon |
|---|---|---|---|
| Multi-brand coverage | Yes — 12+ commercial OEMs | Cummins only | Partial (varies by license) |
| Forced DPF regen | Yes | Yes (Cummins only) | Limited |
| ECU parameter programming | Yes | Yes (Cummins only) | No |
| Actuator tests | Yes | Limited | No |
| Construction / off-highway | Yes | No | No |
| Marine & agricultural diesel | Yes | No | No |
| Ownership model | Yes (via WholeFleet) | Subscription | Subscription |
| Canadian expert support | Yes (WholeFleet) | No | No |
For a dedicated Cummins shop that services nothing else, Insite makes sense. For everyone else, mixed fleets, independent repair shops, operations running PACCAR and Detroit and Mack side by side…Jaltest is the only diesel diagnostic tool that doesn't require you to juggle multiple subscriptions or call a dealer every time you're outside your tool's coverage.

Diesel Engine Diagnostic FAQs
Can Jaltest actually perform a DPF forced regeneration, or just read DPF-related fault codes?
Yes, Jaltest can initiate both stationary and parked DPF regenerations on supported engines. This is a genuine dealer-level function, not a code-reader workaround. When a truck's DPF warning triggers and the driver can't complete an active regen on the road, your technician can connect Jaltest, command the forced regen, and get the truck back in service without a dealer appointment. It works on Cummins, Detroit Diesel, Volvo, PACCAR, and Mack engines, among others. This is one of the most-used features for fleet diesel diagnostic work, and it alone justifies the investment for many high-mileage operations.
Does Jaltest support older diesel engines, or only newer emissions-controlled platforms?
Jaltest covers a broad range of model years, including pre-emissions and legacy diesel engine platforms. While the software is especially capable on modern SCR- and DPF-equipped engines where full ECU and aftertreatment access is critical, it also communicates with older ECM architectures. If you run a mixed fleet that includes older workhorses alongside newer trucks, you won't be leaving older units without diagnostic coverage. Specific model year ranges vary by brand — WholeFleet's support team can confirm coverage for your exact equipment list before you commit.
How is this different from a standard OBD scanner or a generic diesel diagnostic scanner?
The difference is a generic OBD scanner reads generic fault codes — the same codes any $200 tool can pull. Jaltest communicates with the manufacturer's proprietary ECU protocols and accesses OEM-level data and functions that standard scanners can't reach. That includes live parameter data streams, bidirectional actuator tests, forced DPF regen, ECU calibration, and guided diagnostic procedures. Think of the gap this way: a generic diesel diagnostic scanner tells you there's a problem. Jaltest tells you what the problem is, lets you test components to confirm the diagnosis, and in many cases lets you fix it from the same tool — without opening a work order at the dealer.
We service multiple brands. Is Jaltest genuinely suitable for a multi-brand diesel shop?
It's specifically designed for that environment. Multi-brand independent shops are arguably Jaltest's ideal customer — because single-brand dealer tools don't serve them at all. With one Jaltest kit, your technicians can work across Cummins, Detroit Diesel, Mack, Volvo, and PACCAR engines, plus construction equipment, agricultural machinery, and marine diesel applications, all under a single license. There's no need to invest in separate Cummins diagnostic software here and a Detroit Diesel diagnostic tool there. The coverage is consistent, the interface is the same across brands, and your techs only need to learn one platform.
Is Jaltest available in Canada, and is there Canadian support?
Yes, and this is specifically where WholeFleet's position matters. WholeFleet is Canada's leading Jaltest partner, with a support team based in Canada. That means you're working with people who understand Canadian fleet operations, the brands common to Canadian roads and job sites, and the regulatory environment here. You're not dealing with a US distributor who ships a box across the border and considers their job done. WholeFleet provides onboarding, Canadian-based technical support, and access to training through VieTech — in-person and online options are both available.
What exactly is included when I get Jaltest through WholeFleet?
WholeFleet's Jaltest package includes the diagnostic hardware interface, the Jaltest software license, onboarding support from their Canadian team, and access to training through VieTech. Critically, this is an ownership model — you own the hardware and license rather than paying an ongoing monthly rental fee. WholeFleet also offers a free 2-week trial before you commit, and financing options are available for operations that prefer to structure the investment. The full details — including exactly what's in each configuration — are in the pricing guide available for download.
How long does it take for a technician to become productive with Jaltest?
Experienced diesel technicians generally get productive with Jaltest quickly. The interface is logically structured, and the guided Expert Mode helps narrow down complex faults without requiring the tech to memorize OEM-specific diagnostic trees. For shops that want to accelerate the learning curve, WholeFleet's partnership with VieTech provides structured training — including both online modules and in-person sessions — so your techs aren't left figuring it out through trial and error. Most shops report that within the first few weeks of real-world use, technicians are comfortable running the full diagnostic workflow independently.
Can Jaltest eliminate our need for dealer diagnostic callouts entirely?
For most diagnostic work on covered engines, yes. Jaltest provides the same depth of access a dealer technician uses — live data, forced regen, actuator testing, ECU programming, and Expert Mode guided diagnostics. The situations where a dealer is still required are narrowing rapidly: some highly specialized reprogramming events or OEM warranty work that legally requires the OEM to perform may still need dealer involvement. But the routine diagnostic calls — the "we need a tech to come read the truck" callouts that generate most of the invoices — those are entirely replaceable with in-house diesel diagnostics at the Jaltest level. That's where the cost savings are, and that's the target for most fleet operations that switch.
