Code 0802 | Jungheinrich Error

Note on Model Variations: This code is standard across many Jungheinrich series (ETX, EFG, EJE, ETV), but the physical location of the components will vary. Consult your specific truck's spare parts manual (available via the Jungheinrich "Profound" portal) for the exact layout of your model.

In Jungheinrich forklifts, Error Code 0802 generally signals a logical conflict or operational error involving the travel direction switches

. This error occurs when the system detects that both travel directions (forward and reverse) have been selected simultaneously, creating an "implausible" signal for the controller. Understanding Error Code 0802

The error is part of the truck's self-diagnostic system designed to prevent unsafe movement. When the controller receives simultaneous inputs for forward and reverse, it triggers a safety stop to avoid mechanical or electrical damage. Primary Cause: Simultaneous activation of both travel directions. System Impact:

The truck will typically stop traveling, and a warning symbol (often a flashing "Else-Check") may appear on the display. Affected Components:

Travel direction switches, the interface (often Interface 7 Canion), or the Multipilot/Solopilot control handle. Recommended Troubleshooting Steps jungheinrich error code 0802

If you encounter this code, follow these steps to diagnose and resolve the issue: Reset the System:

Switch the truck off and then back on. This can clear temporary logical glitches if the switches were toggled too quickly. Inspect the Control Interface: Check the physical travel switches or the Multipilot/Solopilot

handle for damage or sticking. If a switch is stuck in one position, selecting the opposite direction will trigger Code 0802. Check Wiring and Connections:

Inspect the wiring leading from the control handle to the interface board. Look for short circuits, loose connections, or frayed wires that might be sending a false "closed" signal. Hardware Replacement:

If the switches and wiring are intact, the issue may lie within the Interface 7 Canion Note on Model Variations: This code is standard

or the control handle assembly itself, which may require replacement. Twin Pedal Configuration:

For trucks equipped with twin pedals, check the electrical system specifically for pedal-related faults that might simulate dual-direction input.

Error code 0802 on Jungheinrich forklifts (including models such as ETV, EFG, EJE, and EKS) indicates a general electrical fault or communication error related to the drive motor temperature sensor circuit. While the primary fault is often logged as "Motor Temperature Sensor," the 0802 code specifically points to plausibility errors or short circuits within the sensor wiring harness connecting the traction controller to the drive motor.
