Pop the hood and locate the main fuse box. Identify all fuses associated with the main controllers (drive, steering, hydraulic). Check them for continuity with a multimeter, and do not just rely on a visual check. A hairline crack can be invisible but still cause a failure. Pay particular attention to fuses supplying controllers known to be on the CAN network, as a missing power supply is a primary reason for the "no response" indicated by the 0802 fault. : Indicates multiple areas or the general electrical

If the display lacks data or shows text only partially, check the physical board: Remove the display housing screws and open the enclosure. Look for burned traces, swollen capacitors, or heat damage.

In some older Jungheinrich models, the 0802 code has an alternative interpretation directly related to . The error code can sometimes be broken down as DO4 (Digital Output 4) and 02 (Wire Breakage) , and some sources suggest that on certain trucks, error 08 in combination with 02 specifically indicates a broken wire on a digital output. In such cases, the troubleshooting approach changes to checking the continuity of specific wires from the controller to the component they control, such as a hydraulic valve coil. A hairline crack can be invisible but still cause a failure
