Frequently Asked Questions
Q: What is the TO 00591-41165-81 logic card?
A: The TO 00591-41165-81 is a logic card (controller board) for Toyota EV100LX electric pallet jacks with dual motor drive systems. This circuit board manages motor control, solenoid activation, pump operation, and battery monitoring.
Q: What does the logic card control on an EV100LX?
A: The logic card handles lift motor control, lower motor control, pump solenoid engagement, direction control valves, and battery voltage management. It also manages safety interlocks and operational feedback signals from lift and lower circuits.
Q: Which Toyota EV100LX models and serial ranges use this logic card?
A: The TO 00591-41165-81 fits Toyota EV100LX dual-motor pallet jacks manufactured during specific years. Cross-reference your equipment serial number with Toyota parts documentation to confirm compatibility before ordering.
Q: What are common failure symptoms of a defective logic card?
A: Symptoms include intermittent lift or lower function, complete loss of power even with charged battery, solenoid clicking but no hydraulic flow, motor running continuously without stopping, or error codes displayed on the control panel. Test battery voltage first to rule out low power before assuming card failure.
Q: Can a failed logic card be repaired or must it be replaced?
A: Logic cards are typically not field-repairable. Trace power and signal connections first to rule out connector corrosion or loose wiring. If connections are clean and vehicle behavior persists, the card requires replacement. Keep the defective card for potential core credit or rebuild evaluation.
