The driver input interface (such as a SoloPilot, MultiPilot, or tiller arm)
: Switch the truck off and on again. This can sometimes reset temporary "implausible" signal errors. jungheinrich error code 0802
(e.g., EFG 215, EKS 110) of your Jungheinrich truck to provide more specific technical steps? On the Finch II, what does display error code E0802 mean?
In Jungheinrich's multi-digit event messaging architecture, the prefix generally relates to system interfaces, display electronics, or control voltage configurations. The sub-code 02 targets communication anomalies, specifically an asset missing from the CAN network loop. This public link is valid for 7 days
A simple but crucial cause of 0802 is a loss of power to a specific controller. A technician troubleshooting a Jungheinrich ETV Q20 reported performing standard checks—measuring coil resistances and inspecting wiring—before finally finding an open 9f2 slot fuse (rated at 7.5A/58V). Although the fuse itself was not always the final fix, it pointed to a fundamental power delivery problem. If a controller loses its voltage supply, it cannot power up, cannot communicate over the CAN network, and will be invisible to the rest of the system, triggering the 0802 error.

The tiller head contains multiple microswitches that detect the exact physical position of the arm (vertical, driving zone, or horizontal braking zone). If a switch is physically bent, contaminated with dust, or worn out, it sends an impossible combination of signals to the controller. 2. CAN-Bus Communication Failures
Use a multimeter to run a continuity test across all control circuit fuses, paying close attention to any . Replace any open fuses with identical voltage and amperage ratings.
If calibration fails or the display shows no response, proceed to software diagnostics.
