: The forklift will not move forward or backward, and the mast will not lift, tilt, or sideshift.
This information comes directly from Jungheinrich’s diagnostic descriptions, which instruct the technician to remove the connector and measure the resistance on the respective terminals of the plug connector to check the individual valve coils. On‑off valves typically have a coil resistance of 15–30 Ω.
After making repairs, clear the error using either:
| Repair Action | Estimated Cost (USD) – Parts & Labor | | --- | --- | | Temperature sensor replacement (DIY) | $50 – $120 (sensor only) | | Temperature sensor replacement (dealer) | $250 – $450 | | Wiring harness repair (shop) | $150 – $300 | | New wiring harness (parts only) | $180 – $600 (depending on model) | | Drive controller replacement (dealer) | $1,200 – $2,800 | jungheinrich error code 0802
Clean any dirt, debris, or shrink-wrap plastic wedged around the housing of the button. Step 4: Examine the Wiring Harness
If this code appears, follow these immediate measures to safely assess the situation:
For persistent issues, it is recommended to contact Jungheinrich Service or use the app, providing your serial number and the exact error code for faster diagnosis. : The forklift will not move forward or
During planned maintenance (PM) intervals, specifically check that control module plugs are clean, tight, and free of dust build-up. When to Call a Professional
According to fleet technician repair logs on Forkliftaction Forums , a primary failure point for code 0802 is the control console inside the armrest.
Understanding and Fixing Jungheinrich Error Code 0802 Jungheinrich electric forklifts and pallet jacks are known for reliability, but electronic faults can occasionally halt operations. One common fault code that operators and technicians encounter is . After making repairs, clear the error using either:
Logic error, e.g. both directions selected simultaneously. in the truck depending on the display unit options.
Low voltage or poor battery connections can cause communication drops between modules.
The generally signals a hardware or communication conflict within the truck’s electrical system, often linked to the Multipilot (MP) or Interface (I2, I3, I5) components . Because Jungheinrich uses a structured 5-digit coding system (FEXXS), the leading "0" indicates that several areas of the truck are affected simultaneously. Meaning of Error Code 0802
Locate the main electrical panel (usually found under the seat or main cover).
| Cause | Fix | |-------|-----| | Corroded connector | Replace pin/socket or whole connector housing | | Broken CAN wire | Repair or replace harness section | | Missing termination | Install 120‑ohm resistor (part no. 51157028 example) | | Faulty control unit | Replace (requires Jungheinrich software coding) | | Low voltage | Charge battery, clean main terminals |
