Jungheinrich Error Code 1901 Jun 2026
: Inspect the drive pedal area for any objects (like small stones or thick mats) that might prevent the pedal from returning to its neutral "zero" position. Inspect Wiring
If the error persists even when the pedal is not touched, the following should be inspected: Faulty Potentiometer Jungheinrich Error Code 1901
Follow these steps in order. In most cases, the solution is simple and will require only a few seconds. : Inspect the drive pedal area for any
: Take your foot off the accelerator pedal completely. : Take your foot off the accelerator pedal completely
: If the error persists even when the pedal is physically at rest, there may be a faulty drive pedal sensor or a wiring issue that requires a technician. Machine Maxx USA Related Error Codes
The Controller Area Network (CAN-bus) acts as the nervous system of the forklift, allowing the display, tiller head, steering controller, and traction controller to share data. If a loose wire, pinched harness, or corroded pin interrupts this data stream for even a few milliseconds, the master controller registers a timeout and throws code 1901. 2. Voltage Drops and Battery Degradation
A properly functioning CAN bus requires 120-ohm termination resistors at both ends of the network. If one resistor is missing, damaged, or has the wrong value, signal reflections cause "bit errors" that escalate into a full timeout (Error 1901).
