Diagnostic Code Cause

Correction

1501

Parking brake is released or the parking brake coil 
circuit is open

Check to assure the parking brake is not manually 
released.

1507

Parking Brake Over Current

Parking brake coil is internally shorted or there is a 
problem with the wiring to the brake. 

2C00-2C02

Battery voltage is low     

Charge the batteries with OEM supplied charger. 

2F01

Throttle is depressed during power on or a fault with 
the throttle system

Turn the machine off, assure that the throttle 
button(s) or throttle pedal are not depressed.  Turn

This code can be caused by the traction motor 
having moisture present or being contaminated. 

7600

Brush Motor Circuit Open

The controller is not seeing continuity on the brush 
motor circuit.  This can be caused by the wiring to 
the scrub brush motor(s), corroded connections or a 
faulty motor.

7601-7603

Brush Motor Circuit Over Current

The brush motor output is exceeding its limit.  With 
the scrubber turned off, check for entrapped debris 
around the brush driver(s) and assure the brushes 
turn freely.

7700

Vacuum Motor Circuit Open 

The controller is not seeing continuity on the 
vacuum motor circuit.  This can be caused by the 
wiring to the scrub brush motor(s), corroded 
connections or a faulty motor.

7701-7703

Vacuum Motor Circuit Over Current

The vacuum motor output is exceeding its limit. This 
can be caused by a faulty vacuum motor(s) or 
damaged vacuum motor wiring. 

1E03

Charger / Seat Switch – Charger is plugged in or 
operator is not on the seat of ride on equipment. 

On board charger is plugged into the wall outlet.  Off

out of adjustment. (Operator is not present on seat 
GTR and EX machines Prior to Serial Number 100xxx)

7500

LCD Communication Error

The LCD lost communication to the controller.  Check 
the 6 wire harness between the LCD module and it's 
connections.

7801-7802

Traction Motor Over Current      

The traction motor output is exceeding its limit.  
Check to assure the parking brake is releasing when 
the throttle is engaged.  Assure all wheels that 
contact the floor turn freely.

7804
