Discussion: Jungheinrich ETV Q20 error 0802 - Forklift Action
Review the wiring diagram to identify the fuses assigned to the controller and CAN-bus system.
: In some cases, only half the display may work if the error stems from a voltage regulator issue.
When triggers, it means data packets are dropped or a critical control node has completely dropped off the network . This communication freeze causes immediate symptoms:
The suffering an internal component short. 2. Blown Fuses or Faulty Ignition Contactors
These cases highlight that while the error code points to a communication problem, the root cause can range from a faulty contactor and damaged sensor to a software mismatch on a critical control board.
If the switches and wiring are intact, the issue may lie within the Interface 7 Canion
: If you have recently changed settings, the truck may trigger 0802 because the new parameters were not properly saved to the "Safe" (SSP button).
: A flashing "Warning" or "Attention" symbol typically accompanies the code.
On some Jungheinrich reach trucks, the error 0802 has been specifically linked to the steering controller. One detailed troubleshooting case described a baffling scenario: the error persisted even after the steering controller was replaced with a brand-new part and a known-good part from a working truck.
Check the electronic board underneath the . Look for signs of water ingress, corrosion, or burnt solder components.
Error code on Jungheinrich forklifts (including models such as ETV, EFG, EJE, and EKS) indicates a general electrical fault or communication error related to the drive motor temperature sensor circuit. While the primary fault is often logged as "Motor Temperature Sensor," the 0802 code specifically points to plausibility errors or short circuits within the sensor wiring harness connecting the traction controller to the drive motor.
