Error Code Denitions:
• Short Circuit/Output Fault:
Controller detected a short circuit or other fault on the output circuit.
Check wiring.
• Battery Under Voltage:
B+ Voltage lower than Low Voltage Battery Setting. Check pack
voltage or program settings.
• Battery Over Voltage:
B+ Voltage Higher than Over Voltage Battery Setting. Check pack
voltage or program settings
• Over temperature:
Busbar temperature exceeds 90
o
C. Let controller cool and/or add fan.
• Throttle power Fault:
This is a 5V fault, if the speed sensor gets damaged this alarm will be
one of the alarms triggered. Can also be caused by a fault in voltage
based throttles
• Pre-charge Failure:
 B+voltageandKSIvoltagedierbymorethan5v.Stucksolenoid.
• Under Temp:
Busbar Temperature reads less than -20
o
C
• High Throttle Over range & High Throttle Under range:
High Side of throttle signal is outside of acceptable window for that
throttle type. Check and/or replace throttle. Change throttle type to
correct throttle installed on car.
• Low Throttle Over range & Low Throttle Under range:
Low Side of throttle signal is outside of acceptable window for that
throttle type. Check and/or replace throttle. Change throttle type to
correct throttle installed on car.
• Bad Variable Set Loaded:
Alltrax loaded variable data is missing or corrupted. Contact Alltrax
• Throttle/Brake Range:
The RXV has a “throttle” built into the brake pedal to communicate
with the motor brake. This alarm indicates an error in that signal.
