Dealer-Level Yale Forklift Diagnostic Tool
Full Coverage, No Dealer Required
A Yale forklift sitting idle costs real money. Whether it's waiting on a dealer callout, stuck in a fault code loop your current tool can't decode, or tied up for days because no one on your team can trigger a DPF regen — every hour of downtime has a price tag. Jaltest, available through WholeFleet Diagnostics, gives your technicians dealer-level access to Yale systems from day one. Read faults, access service menus, run regenerations, and get your equipment moving again — without waiting on anyone.

What Jaltest Can Do With Your Yale Forklifts
Jaltest isn't a generic scan tool with a Yale logo on the splash screen. It's the same diagnostic platform used by professional equipment dealers — built for technicians who need real access, not surface-level fault reading.
Yale Fault Code Reading & Clearing
Jaltest reads and clears DTCs across all Yale electronic control systems — transmission, hydraulics, engine management, and more. You get the fault code, the affected system, the likely cause, and guided resolution steps. No more looking up codes in a binder or calling the dealer to ask what "E2-23" actually means.
Works across all Yale propulsion types: diesel, electric, and LPG/propane. If your fleet runs multiple fuel types, one tool handles all of them.
Yale Service Password Access Without the Dealer
The Yale service password (also called the Yale menu password or service unlock) is one of the most common reasons fleets make expensive dealer callouts. Certain parameter changes, calibrations, and advanced service functions sit behind password-protected menus — and without access, your techs are stuck.
Jaltest provides the access codes and the menu navigation to get into those locked service functions directly. That's not a workaround. That's how the tool is designed.
DPF Forced Regeneration (Diesel Yale Models)
Diesel Yale forklifts with DPF systems require forced regeneration when passive regen doesn't complete — and the procedure isn't identical across models. The process on a GDP 50MX, for example, differs from the steps on the GDP 60VX. Jaltest walks your technicians through the correct model-specific regen sequence, monitors temperature and pressure values in real time, and confirms completion. No guesswork. No repeated failed attempts that clog the filter further.
If your fleet runs Yale diesel models with particulate filters, this capability alone can justify the tool.
Live Data Monitoring & Recording
Watch ECM inputs and outputs in real time — engine RPM, hydraulic pressure, battery voltage, temperature sensors, solenoid states, and more. Jaltest lets you record live data sessions and play them back, which is invaluable for tracking down intermittent faults that don't throw a consistent code.
Diagram it. Record it. Diagnose it. That's how experienced technicians work.
Injector Coding & Parameter Calibration
On Yale diesel models, injector replacement requires coding the new injector's trim values into the ECM. Without this step, you'll get rough running and potential fault codes even after a clean install. Jaltest handles injector coding directly — no separate OEM programmer required.
Parameter calibration functions also cover hydraulic flow settings, load sensor calibration, and drive controller adjustments depending on the model.
Wiring Diagrams & Full System Technical Data
Jaltest includes embedded wiring diagrams, component locations, and full technical documentation for Yale models — organized by system, accessible right from the diagnostic interface. Your technicians don't need to cross-reference three different manuals while holding a multimeter. The information is where they need it, when they need it.
Yale Fault Code List
Common Yale Forklift Fault Codes
Jaltest provides guided resolution for hundreds of Yale-specific DTCs. Here's a cross-section of commonly encountered faults across major systems.
| Fault Code | System | Description |
|---|---|---|
| E2-23 | Transmission ECU | Communication fault — TCU to main controller |
| E1-11 | Engine Management | Coolant temperature sensor out of range |
| E3-05 | Hydraulics | Lift pressure sensor signal fault |
| E7-01 | DPF / Aftertreatment | Particulate filter regeneration required |
| E7-04 | DPF / Aftertreatment | Regen inhibited — check inlet temp sensor |
| E4-12 | Drive System (Electric) | Curtis controller overcurrent fault |
| E4-31 | Drive System (Electric) | Motor temperature exceeded threshold |
| E5-02 | Load Management | Load sensor calibration fault |
| E6-15 | LPG / Fuel System | Fuel pressure sensor fault — propane models |
| E9-07 | CAN Bus | Lost communication — auxiliary controller |
| Jaltest provides guided resolution — including probable causes, related system checks, and step-by-step repair procedures — for hundreds of Yale-specific DTCs across all model lines. | ||

Why WholeFleet
Why Fleet Managers Choose Jaltest Over Yale OEM Software
Yale's OEM PC Service Tool is designed for dealers. Jaltest is designed for the people who operate and maintain the equipment every day.
One Tool for Your Entire Fleet: Yale's OEM tool covers Yale. Jaltest covers 30+ MHE brands — Yale, Hyster, Crown, Toyota, Linde, and more — plus commercial vehicles, construction, and agriculture. For mixed fleets, that consolidation has real financial and operational value.
Eliminate Dealer Callout Costs: Some WholeFleet customers were spending over $100,000 per year on dealer callouts before bringing diagnostics in-house. The travel charges, labour rates, and wait times add up fast — especially when the repair only needed a service password or parameter reset to begin.
You Own It: Jaltest is a purchased tool. You pay for the hardware and the software licence, and you own it. Annual updates are available but not mandatory — your tool doesn't stop working if you skip a renewal cycle. That's not a rental. You own it.
Canadian Support. Real Training. Real People.: WholeFleet is a Canadian company with a team that answers the phone. Local rep coverage, onboarding training through our partnership with VieTech, and ongoing support mean your team is never left reading a manual and hoping for the best.
“We have tried every other aftermarket electronic diagnostic tool and they all missed the mark with lack of capability or poor user experience...
WholeFleet introduced us to Jaltest with a two-week trial and provided introductory software training to all our techs. Hands-down the most capable and user-friendly software we have ever experienced! All our techs bought in!
As a bonus were able to eliminate other license subscriptions, reducing our annual spend on diagnostic software.”
