Jungheinrich Etv 216 Error Codes -

Low voltage during system start. Check the battery voltage and main contactor.

| Code | Description | Common Root Cause | Immediate Action | |------|-------------|--------------------|-------------------| | | Battery undervoltage (cutoff during lift/lower) | Severely discharged battery or weak cell | Check specific gravity (flooded lead-acid) or cell voltages. Perform equalization charge. | | 121 14 | Battery overvoltage | Charger malfunction (overcharging) or regen energy with no absorption | Immediately stop truck. Check charger output voltage. Inspect contactor precharge circuit. | | 121 32 | Battery temperature sensor failure (BTS) | Sensor missing, broken wire, or sensor out of range (-40°C or +150°C) | Locate BTS on battery pack. Measure resistance (should be around 10k at 25°C). Replace sensor. | | 141 01 | Charger communication fault (CANbus) | Loose CAN H/L wires or incompatible charger profile | Check terminating resistors (120 ohm) on charger CANbus. Re-flash charger profile via Jungheinrich Service Tool. | jungheinrich etv 216 error codes
