Action
• Severe B+ Undervoltage Set: Capacitor bank voltage dropped
below Severe Undervoltage limit with FET bridge enabled.
• Effect: Reduced Drive Torque
• Possible Cause:
• Battery menu parameters are misadjusted
• Non-controller system drain on battery
• Battery resisitance too high
• Battery disconnected while driving
• Blown B+ fuse or main contactor not closed
• Pump BDI Fault Set: BDI Percentage charge at 0% when the pump
was activated.
• Effect: ShutdownPump
• Possible Cause:
• Battery is fully discharged
• BDI parameters are mis-tuned
• The Ground Module momentarily measured excessively high battery
voltage (VBAT) (>32.0V) and entered SafeMode to protect system
devices. This may be due to improper battery charging or incorrect
voltage batteries being used.
• The Ground Module momentarily measured excessively high battery
voltage (VBAT) (>32.0V) and entered SafeMode. This may be due to
improper battery charging or incorrect voltage batteries being used.
