Jungheinrich — Error Code 0802 Exclusive

Jungheinrich error codes are typically four-digit "event messages" that provide diagnostic information for specific forklift systems. Meaning of Error Code 0802

• With an oscilloscope or CAN tester, measure differential CAN_H/CAN_L during power up; look for absent frames, noise, or wrong voltages.
• Check termination resistance across CAN_H–CAN_L (target ≈ 120 Ω for a single terminated bus or 60 Ω if two 120 Ω terminators).

4. Main Controller Failure (Rare)

• A damaged analog input channel on the Master Drive Controller (e.g., Siemens or ZAPI unit) can falsely interpret correct pedal signals as “implausible.”

Expected values:

• Jungheinrich ETV 110 / 112 / 114 / 116 (Reach trucks)
• Jungheinrich EFG 213 – 220 (Electric counterbalance trucks)
• Jungheinrich EKS 110 – 115 (High-lift order pickers)
• Jungheinrich EJC 112 – 118 (Electric pallet stackers)
