Before calling a certified field technician, fleet managers and maintenance personnel can perform several basic diagnostic checks to isolate the issue. Step 1: Perform a Hard Reset
When operating a modern Jungheinrich forklift—such as the or the ETV reach truck series —encountering an unexpected fault code can bring your warehouse operations to an immediate halt. One of the most common yet generic codes that operators and fleet managers face is Error Code 0802 .
Ensure the battery is fully charged and maintaining stable voltage under load, as low voltage can cause erratic controller behavior. Titan Logix Corp

Jungheinrich is a well-known German manufacturer of material handling equipment, including forklifts, pallet trucks, and warehouse equipment. Their machines are widely used in logistics and warehousing operations globally. However, like any complex machinery, Jungheinrich equipment can sometimes encounter errors or faults that disrupt operation. This report focuses on one such error, the Jungheinrich Error Code 0802.
The most frequent cause of this code is physical damage to the contactor contacts. When the forklift operates under high loads, or if the battery voltage is critically low, drawing power creates intense electrical arcing across the contacts. Over time, or during a sudden high-current spike, this heat can literally weld the copper tips together. When the controller terminates power to the contactor coil, the spring cannot pull the welded contacts apart. 2. Faulty Contactor Return Spring
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.

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.
Based on your diagnosis, proceed with the appropriate fix.
: One of the primary controllers (traction, steering, or hydraulic) is not responding to the interface board.
Industrial environments expose material handling equipment to severe vibrations, thermal expansion, and mechanical flexing. This wear can result in:
