: Travel (traction) and lifting functions (hydraulics) are completely locked out to prevent uncommanded movements.
Corrupted data or loose connections along the Controller Area Network (CAN-bus) lines will interrupt the safety signal.
The generally signals a hardware or communication conflict within the truck’s electrical system, often linked to the Multipilot (MP) or Interface (I2, I3, I5) components . Because Jungheinrich uses a structured 5-digit coding system (FEXXS), the leading "0" indicates that several areas of the truck are affected simultaneously. Meaning of Error Code 0802 jungheinrich error code 0802
Low battery voltage or faulty power connections can drop communication across the board. Wiring/CAN-bus Faults:
Jungheinrich Forklift Error Codes - Machine Maxx USA : Travel (traction) and lifting functions (hydraulics) are
The system locks down operation to prevent erratic movement, throwing across the digital console. 🛠️ Common Causes of Error Code 0802
A properly functioning, terminated CAN network should read approximately (two 120-ohm resistors wired in parallel). A reading of 120 ohms indicates an open circuit or a missing termination resistor, while 0 ohms indicates a short circuit between the data wires. When to Seek Professional Support Because Jungheinrich uses a structured 5-digit coding system
Confirm that the active project file matches your specific truck series (e.g., FG_4xx5xx ).
If your Jungheinrich truck shows error 0802, try these steps in order, ensuring safety procedures (lifting the truck, disconnecting the battery) are followed. 1. Initial Checks (Non-invasive) Power off the forklift, wait approximately seconds, and power it back on.
