Measure the resistance across the CAN-High and CAN-Low communication lines using your multimeter.
In the world of material handling, downtime is the enemy of productivity. When a Jungheinrich forklift—whether a reach truck, electric counterbalance, or pallet stacker—flashes an error code on its display panel, it is a cry for help from the truck’s sophisticated control system.
Also measure resistance between the two sensor pins in the harness. It should be when the motor is disconnected. Any reading indicates a harness short.
In Jungheinrich forklifts (specifically newer EFG models and reach trucks like the ETV series), Error Code 0802 generally signals a communication or signal plausibility issue between the truck’s main control systems
If the truck has had a motor replacement with a different spec (e.g., 36V motor in a 48V truck), the resistance curve of the thermistor may not match the ECU’s map, triggering code 0802 instantly.
Understanding why the error occurred is half the battle. Here are the most common causes ranked by probability:
