How do I fix a “Driver shorted” error on my Hyster Forklifts?
If your Hyster Forklifts displays “Driver shorted”, check if there is a short circuit or a low pull-down impedance between NMC (CNA#16) and –BATT. If there isn't, the driver circuit is damaged in the logic board, which must be replaced.
What does “Pot accel mism” mean on my Hyster Forklifts?
If your Hyster Forklifts displays “Pot accel mism”, check the potentiometers. If the potentiometer works properly and the wiring is correct, the ACE-2 logic board needs replacing.
What does “Logic failure #3” mean on Hyster D435?
If your Hyster Forklifts displays “Logic failure #3”, it means there is a hardware problem pertaining to the logic card as a protection against high current values (overload). When it manifests itself the ACE logic board needs replacing.
What to do if my Hyster D435 Forklifts shows “Pev not ok”?
If your Hyster Forklifts displays “Pev not ok”, check the connector A17.
How do I troubleshoot “Sens mot temp ko” on my Hyster D435 Forklifts?
If your Hyster Forklifts displays “Sens mot temp ko”, check the ohm value of the sensor and the wire harness assembly of the sensor. If the sensor is OK, then the problem is in the ACE logic board, proceed with replacement.
What does “Tiller open” mean on Hyster Forklifts?
If your Hyster Forklifts displays “Tiller open”, the warning disappears with the next drive request.
What does “Dir sel out rang” mean on my Hyster D435 Forklifts?
If your Hyster Forklifts displays “Dir sel out rang”, check the connections of the switch and measure the signal with a tester.
What does it mean when my Hyster Forklifts displays “Vacc not ok”?
If your Hyster Forklifts shows “Vacc not ok”, it means that the ACCELERATOR reading in the TESTER menu is 1.0V over the min. PROGRAM VACC acquisition when the throttle is released. Acquire the maximum and minimum value of the potentiometer via the PROGRAM VACC function. If the alarm persists, check the mechanical calibration and the operation of the potentiometer. If the alarm is not deactivated, the fault is in the ACE logic board, therefore proceed with replacement.
What should I do if my Hyster Forklifts shows “Contactor open”?
If your Hyster Forklifts displays “Contactor open”, it means that the main contactor coil has been activated by the control device, but the contactor fails to close. It could be a problem with the contacts in the MC not working (not inserted), try replacing the MC. If the MC contactors work properly, the problem lies within the control device, so replace it.
What to do if I see an “Eeprom ko” alarm on my Hyster D435?
If the “Eeprom ko” alarm appears on your Hyster Forklifts, it indicates a hardware or software defect in the integrated non-volatile memory. Try performing a CLEAR EEPROM operation (refer to the console manual). Power cycle the device using the key to check if the alarm disappears. If the alarm persists, the control device needs replacement. If the alarm disappears, the parameters will be replaced by the default ones.
