This error indicates a critical electrical fault in the drive system, often accompanied by Info 22 and Error 70. In AC drive trucks, the error may be triggered by a faulty speed sensor in connection with AS4814Plus controllers. The error description notes: "19-Disable armature faulty; Power stage short circuit (for AC) The error may be triggered by the faulty speed sensor in connection with AS4814Plus controllers. A short circuit cannot be resolved by switching the truck off/on".
Failed steering encoder, mechanical binding in the steering gearbox, or a blown fuse in the steering controller.
Component failures (e.g., motor, controller).
Check battery connections for weak contact, check battery voltage, and ensure the charger is disconnected. Inspect the main contactor wiring. 018-1 / 018-4 (Armature Power Stage Fault): jungheinrich etv 216 error codes
| Code | Description | Common Root Cause | Immediate Action | |------|-------------|--------------------|-------------------| | | Hydraulic pump motor overcurrent | Mechanical jamming in pump, hydraulic oil too thick, or shorted pump motor | Check oil viscosity (recommended HLP 32 or 46). Measure pump motor current with clamp meter. Replace pump if seized. | | 313 08 | Pump motor speed error (feedback missing) | AC motor encoder failure or broken belt between motor and pump | Inspect encoder on pump motor. Clean optical disc. Check 5V supply to encoder. | | 442 05 | Lift valve spool position error | Spool stuck due to contamination or coil failure | Manually actuate valve (carefully). Measure coil resistance (20–40Ω). Flush hydraulic block. | | 455 12 | Reach carriage limit switch timeout | Carriage did not retract within 2 seconds of command | Inspect limit switch LS101/LS102. Adjust cam or replace microswitch. | | 462 03 | Side-shift sensor short circuit | Wiring chafed on chassis or sensor destroyed | Inspect wiring from side-shift cylinder to FGC. Replace linear potentiometer. |
Many 1xx and 5xx errors are side effects of low voltage. Check the battery under load by lifting a heavy pallet. If the voltage drops sharply, charge or service the battery before replacing any components. Step 3: Inspect the Wire Harnesses
The code appears as soon as you touch the steering wheel, making the truck difficult or impossible to steer properly. This error indicates a critical electrical fault in
Cause: Operator holding the joystick while turning on the key switch, or a defective joystick potentiometer.
Wait 3 to 5 minutes to allow the residual voltage in the controller capacitors to drain fully. Reconnect the battery firmly and restart the truck. Step 2: Check the Battery State of Charge (SoC) and Voltage
A battery might read 48V at rest, but drop to 35V the moment the lift pump engages, triggering a system error. Watch the battery display icon during operation to see if it plummets under load. When to Call a Certified Jungheinrich Technician A short circuit cannot be resolved by switching
Check the steering fuse in the main electrical compartment. Inspect the steering chains or gears for physical obstructions. A technician will often need to recalibrate the steering zero-point using Jungheinrich diagnostic software (JUDIT). Error Code 3102: Steering Motor Overcurrent
The Jungheinrich ETV 216 reach truck uses a "system message" (E-code) system. These messages are designed to identify faults within the traction, hydraulic, or steering systems. When a fault occurs, the lift truck might go into "creep mode" (slow speed) or shut down completely for safety. Errors generally fall into two categories:
Damaged pedal return spring, debris jammed under the accelerator, or a faulty potentiometer.
Short circuit in the valve coil or damaged wiring harness.
| 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.
