Jungheinrich Error Code 0802 Jun 2026
Understanding and Fixing Jungheinrich Error Code 0802 The appearance of Error Code 0802 on your Jungheinrich forklift
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.
When 0802 is triggered, the forklift will often enter a "safety mode," restricting or completely disabling hydraulic functions (lifting/lowering) to prevent further damage. Primary Causes of Error Code 0802
The main contactor acts as a heavy-duty, electronically controlled switch between the high-capacity battery pack and the forklift’s internal motor controllers. jungheinrich error code 0802
Inspect the board for visible damage; replacement is often necessary. Loose connections or frayed wires in the control arm. Check all wire connections to the hydraulic controls. Joystick / Lever Faulty sensor in the Multi-Pilot or Solo-Pilot handle.
If a broken wire is found:
The 0802 error appears on Jungheinrich dashboards, often accompanied by a blank screen or a locked‑out truck. Unlike simpler fault codes, 0802 is not a direct indication of a single failed component; rather, it is a that typically points to one of two primary issues: Understanding and Fixing Jungheinrich Error Code 0802 The
Inspect the casing for signs of overheating, melted plastic, or a burning odor.
| Aspect | Detail | |--------|--------| | | 0802 | | Meaning | Accelerator pedal signal implausible (voltage out of range) | | Primary Cause | Faulty pedal sensor or wiring | | Typical Fix | Replace pedal assembly or repair harness | | Can the truck move? | No — travel disabled | | DIY possible? | Yes, with multimeter and basic electrical knowledge | | Dealer required? | For controller replacement or advanced calibration |
Sometimes, an error is caused by a temporary electronic glitch. Turn off the forklift. Disconnect the battery for approximately 5-10 minutes. Reconnect the battery and start the machine. If the code 0802 reappears, it is a persistent fault. 2. Check the Battery Condition A low or dying battery can cause sensor issues. Ensure the battery is fully charged. Check for corrosion on terminals. 3. Inspect the Lift Sensors This is the most likely cause. Locate the lift height sensor, typically found on the mast. Primary Causes of Error Code 0802 The main
: Measure the resistance between pins 3 and 8 on the diagnostic port. A healthy circuit should typically read approximately 60 ohms ( Inspect Wiring & Connections :
If you have access to a known‑good truck of the same model:
The traction motor is equipped with a or an NTC (Negative Temperature Coefficient) sensor to monitor winding temperature. The controller (e.g., Jungheinrich FSF or ZAPI AC-2/AC-3) sends a low-voltage reference signal through this sensor.
