Troubleshooting: Battery Charger Error and Fault Codes
(Model 04590)
•
Depress the traction pedal in the forward direction slowly. Pedal Fwd should
change from O to O
FF
2 voltage should decrease as the pedal is depressed forward. If not, the
traction pedal or its circuit wiring is faulty and should be tested.
•
Depress the traction pedal in the reverse direction slowly. Pedal Rev should
change from O to O
FF
Sig 2 voltage should increase as the pedal is depressed rearward. If not, the
traction pedal or its circuit wiring is faulty and should be tested.
•
When the traction pedal is released, the pedal should return to neutral as
indicated by both Pedal Fwd and Pedal Rev being O
pedal may require re-calibration.
•
TRXN 1 Logic V, TRXN 2 Logic V, and TRXN 3 Logic V (if equipped with
optional 3WD) should each display 48V system voltage. If not, an issue with
the logic circuit wiring or the logic relay may exist.
•
When the vehicle is stationary, TRXN 1 Speed, TRXN 2 Speed, and TRXN 3
Speed (if equipped with optional 3WD) should display 0.0 mph/kph. When the
vehicle is traveling in a straight line, the traction speeds displayed should be
approximately the same. If not, the traction motors may require re-calibration.
•
TRXN 3 Bus V (if equipped with optional 3WD) should display 48V system
voltage. If not, an issue with the power supply circuit wiring to the optional
3WD motor may exist.
Using the Outputs Screen
Note: An inappropriate output reading may indicate an issue with the
controller. Contact your Authorized Toro Distributor for assistance with controller
reprogramming or replacement.
• Once the required conditions are satisfied (operator in the seat and manual
parking brake disengaged), Pbrake Release should be O
automatic parking brake is disengaged (brake actuator energized). If the
operator raises out of the seat or the manual parking brake is engaged, Pbrake
Release should be O
FF
(brake actuator de-energized). If the output reading is appropriate and the
vehicle does not perform correctly, the brake actuator or its circuit wiring may be
faulty and should be tested.
