Jungheinrich Error Code 0802 New! Jun 2026

Jungheinrich forklifts utilize a Controller Area Network (CAN-bus) system. This specialized network serves as the forklift's central nervous system, allowing multiple onboard microcontrollers and modules to share data in real time. When you turn the ignition key, the interface display controller initiates a high-speed "handshake" sequence with all critical auxiliary modules, including:

Comprehensive Troubleshooting Guide for Jungheinrich Error Code 0802

The truck will typically stop traveling, and a warning symbol (often a flashing "Else-Check") may appear on the display. Affected Components: jungheinrich error code 0802

Here’s a practical troubleshooting guide for the , typically found on Jungheinrich forklifts (especially ETV, EJE, EKX, and EFG series with CAN-bus systems).

The most straightforward cause is a on the circuit associated with digital output 08. This can be a simple break, a corroded pin, or a connector that has vibrated loose. On reach trucks and electric counterbalances (like the

On reach trucks and electric counterbalances (like the ETV or EFG series), liquid ingress or physical stress can short out the electronic joystick board or Multipilot assembly inside the armrest.

Indirectly. On some models, the controller disables the drive motor but leaves the parking brake active. However, if the controller loses 5V reference, the parking brake solenoid may default to “locked” (truck cannot be pushed). if the controller loses 5V reference

A surprising number of 0802 errors stem from . Two physically identical boards can have different firmware versions – one programmed for drive/braking, the other for hydraulics. Swapping them between trucks or even between positions on the same truck can trigger an 0802 error.
