Jungheinrich Error Code 0802 _best_ -
Based on technical documentation for Jungheinrich forklifts (particularly models like the ETV, EKS, EFG, etc.), the error code 0802 typically indicates a CAN bus (Controller Area Network) communication timeout or a receive error.
Here is the breakdown of the code and the recommended troubleshooting steps. jungheinrich error code 0802
Preventing Error Code 0802 in the Future
- Regular cleaning: Dust and moisture are enemies of the pedal sensor. Use compressed air weekly on the pedal housing.
- Floor plate sealing: Ensure rubber gaskets under the floor plate are intact. In cold storage, apply silicone sealant around the pedal wire exit.
- Operator training: Avoid resting a foot on the accelerator while the truck is idle — this can drift the idle voltage over time.
- Annual calibration: Have a Jungheinrich technician re-calibrate pedals during preventive maintenance (every 1000 operating hours).
- Battery disconnect procedure: Always turn the key OFF before disconnecting the battery to prevent voltage spikes that corrupt pedal learning.
Tools You Will Need:
- Digital multimeter with resistance measurement (ohms).
- Jungheinrich diagnostic software (e.g., “Jungheinrich CanBox” or “Jungheinrich Service Tool”) – recommended but not strictly required.
- Wiring diagram for your specific model.
- Basic hand tools (screwdrivers, Torx bits, contact cleaner).
4. Step‑by‑step troubleshooting
Tools You Will Need:
- Multimeter (capable of DC volts and continuity)
- Jungheinrich “J’Diagnose” software & laptop (for advanced users)
- Wiring diagram (model-specific)
- Replacement accelerator pedal assembly (for testing)
Step 5: Advanced Diagnostics with J’Diagnose
Connect a laptop running Jungheinrich’s proprietary software via the round 6-pin or 9-pin diagnostic port (usually near the controller). Regular cleaning: Dust and moisture are enemies of
- Navigate to Traction System → Analog Inputs.
- Observe live values for Accelerator Pedal Raw %.
- At idle: 0% – 5% (depends on model).
- At full throttle: 95% – 100%.
- If raw % jumps erratically or never reaches 100%, check the pedal calibration table. Re-teach the pedal limits.
Note: Unauthorized software modifications may void warranties. Always use a certified Jungheinrich technician if you lack training. Tools You Will Need:

7. Important safety notes
- Disconnect battery before handling CAN bus connectors.
- Do not probe CAN wires with a test light (use multimeter or oscilloscope).
- Some controllers store configuration – swapping without software can trigger more errors.
