A new Ground Module costs EUR 1 400–2 600 with a 6–10 week lead time. Regeneration at Acore costs EUR 300–750 with a 3–7 business day turnaround.
JLG Controller Types — What Fails Most Often
| Module | Function | Common Failures | Repair Cost |
|---|---|---|---|
| Ground Module (GM) | Drive, engine, pump control | H-bridge MOSFET, filter capacitors, J1–J4 connectors | EUR 300–700 |
| Platform Module (PM) | Platform/basket control, joystick | Microcontroller, 5V supply, analogue inputs | EUR 220–550 |
| TCM (Tilt Control Module) | Tilt sensor, motion interlock | MEMS accelerometer, firmware, connectors | EUR 200–450 |
| ADE (Air Drive Electronics) | Electric motor, battery BMS | IGBT driver, DC-link capacitors, thermistors | EUR 370–875 |
Most Common JLG Fault Codes
| Code | Meaning | Cause | Repair |
|---|---|---|---|
| 0031 | Ground Module CAN comm error | Damaged CAN controller IC, wiring short | CAN IC replacement, harness repair |
| 0188 | Platform Module 24V supply error | Failed DC/DC regulator, harness break | Replace DC/DC regulator |
| 0190 | Hydraulic pump driver fault | Blown MOSFET in GM, ground short | MOSFET replacement + thermal inspection |
| 0502 | Tilt sensor (TCM) failure | Damaged MEMS, calibration error, moisture | Replace TCM module or accelerometer |
| 0110 | Battery charging fault (ADE) | Failed BMS, cell damage, measurement error | BMS regeneration, cell test |
Repair Process
- Initial diagnosis — fault code readout via JLG Analyzer Pro or CAN analyser, visual PCB inspection under microscope
- Damage identification — resistance, capacitance and supply voltage measurements; thermal imaging under load
- Component replacement — OEM or certified equivalents (MOSFET, Panasonic capacitors, Microchip CAN IC)
- Programming and calibration — firmware via J-TAG/CAN, TCM tilt calibration, ADE parametrisation
- Load test — minimum 2-hour simulation on test bench at full load
- Dispatch or on-site installation — next-day courier or on-site fitting within 30 km of Knurów
Why Repair Instead of Buying New?
A new JLG Ground Module 1600292 costs EUR 1 400–2 600 from European distributors, with 6–10 weeks lead time. Regeneration at Acore costs 3–5 times less at a 3–7 business day turnaround. Every repair is covered by a 12-month warranty. For construction companies and rental fleets, machine downtime costs far exceed the repair investment.
Service Area
Acore accepts controllers by courier from all of Poland and Europe. On-site service within 30 km of Knurów (Gliwice, Rybnik, Zabrze, Bytom, Tychy). Operating hours: Mon–Fri 8:00–16:00.
FAQ
- Can you repair a JLG controller without the machine serial number?
- Yes — only the module part number (e.g. 1600292) or machine model is needed for electrical repair.
- Is calibration required after repair?
- The TCM requires on-machine calibration after replacement. GM and PM are programmed and tested on our bench and require no additional calibration.
- Do you offer exchange units?
- Yes — we hold tested JLG modules as rotational spares, reducing downtime to 1 business day.
