For a technician or warehouse manager, seeing on a Jungheinrich display can be a frustrating "stop-work" moment. On many Jungheinrich EFG series forklifts, this specific code typically signals a communication failure or a missing component on the CAN-bus system. Essentially, the truck’s central "brain" is calling out to a part, and that part isn't answering. What Does 0802 Actually Mean?
Based on technical documentation from Jungheinrich Fault Guides and community discussions on Forkliftaction , the following components should be inspected:
The error code "0802" is related to Jungheinrich, a German-based manufacturer of forklifts and material handling equipment. After conducting research, I found that this error code is associated with their electronic control systems.

On trucks equipped with SW60 or similar DC contactors: jungheinrich error code 0802
Error code 0802 on Jungheinrich material-handling equipment is a common fault that typically points to a communication or sensor problem in the electric drive / traction control system. Below is a concise, reader-friendly guide that explains what the code likely means, how to troubleshoot it, and when to call a technician.
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.
One of the traction controllers might fail to communicate during power-up.
The most expensive and time‑consuming cause is a . Several forum threads describe cases where replacing the part (e.g., part number 51169229 ) resolved the error. For a technician or warehouse manager, seeing on
If your truck displays code 0802, follow these diagnostic steps: Turn the truck completely off and remove the key.
Inspect the electrical compartments for any , particularly focusing on the controller circuit fuses. Examine the ignition contactor for damage. 4. CANbus Wiring Inspection
If you are seeing "0802" flashing on your Jungheinrich’s display panel, your truck may experience reduced performance, a complete drive lockout, or intermittent shutdowns. This article provides a deep dive into what error code 0802 means, its root causes, step-by-step diagnostic procedures, and practical solutions to get your forklift back in operation.
Remove the plastic covers around the tiller arm joint. What Does 0802 Actually Mean
Inspect the wiring harness routing down to the traction modules and the mast sensors. Check for pinched or exposed wires that might be grounding against the chassis. Step 4: Run CAN Bus Resistance Tests
In the Jungheinrich diagnostic hierarchy, Error generally refers to a fault in the Steer Angle Sensor (or Steer Encoder) circuit .
An interruption in low-voltage control power will trigger communication faults.
Reconnect the battery firmly and turn the key back on. If a minor data lag caused the timeout, the code will clear.
