Jungheinrich Error Code 0802 [repack] Jun 2026

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

The CAN network relies on a steady power supply to initialize individual module nodes. A failure of the small (often part number 52018885) or an open sub-fuse (such as the 7.5A / 58V circuit slots) will instantly isolate a controller from the boot cycle. 2. Defective Operator Interface Controls

Before working on the electrical system, ensure the truck is parked safely. Disconnect the battery (remove the plug) and wait at least 5 minutes for the capacitors in the controllers to discharge.

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 jungheinrich error code 0802

CAN-bus Data Communication Network / Controller Architecture

An open fuse in the control circuit (e.g., a 7.5a/58v fuse) can cause a loss of power to a component, triggering the error. Step-by-Step Troubleshooting for 0802 For trucks equipped with twin pedals, check the

If the hardware is intact, connect the Jungheinrich diagnostic software (JUDIT) via the service interface to recalibrate the tiller head travel parameters and clear the persistent fault log. Preventative Maintenance Practices

A healthy CAN-bus network with two functional parallel terminating resistors should register approximately 60 Ohms . If your meter reads 120 Ohms , one of the terminating links or module connections is wide open. A reading near 0 Ohms indicates a direct short circuit in the wiring harness.

While a depleted battery usually yields dedicated low-voltage warnings, an extreme voltage sag under initial load can drop potential below the minimum operating threshold for digital microprocessors (typically Before calling a certified field technician, fleet managers

If you are unfamiliar with the CANbus system or electrical components, it is strongly recommended to contact a certified Jungheinrich technician to avoid damaging the controllers.
