CANbus FAILURE: GROUND MODULE
The power module is receiving from the platform module but not the ground module. This should not be possible!
CANbus FAILURE: PLATFORM MODULE
The power module is receiving from the ground module but not the platform module. This is probably due to wir-
ing problems between the platform and ground modules.
CANbus FAILURE: POWER MODULE The power module is not receiving acknowledgments from the platform or
ground modules to transmitted data. This is probably due to wiring problems between the ground and power
modules.
7/7
Flash code 7/7 indicates problems with a motor.
CAPACITOR BANK FAULT - CHECK POWER CIRCUITS
The capacitor bank is not charging. This is probably due to a power wiring error causing illegal current drain; it
could also be due to a very low battery supply.
OPEN-CIRCUIT PUMP MOTOR
Pump point A is collapsing when the pump MOSFETs are pulsed. This is probably due to an open circuit pump
motor or a power wiring error.
OPEN-CIRCUIT DIRECTIONAL CONTACTOR OR TRACTION MOTOR
Traction point A is collapsing when the traction MOSFETs are pulsed. This is probably due to an open circuit traction
motor or a power wiring error. NOTE: This fault is unlikely to be seen due to interaction with speed control.
PUMP POINT A LOW - CHECK POWER CIRCUITS
Pump point A is near 0V when the pump MOSFETs are off. This is probably due to a power
STALLED TRACTION MOTOR
The power module traction MOSFET protection circuit is active. This is due to massive current drain and could be a
stalled traction motor or a power wiring error.
STALLED PUMP MOTOR
The power module pump MOSFET protection circuit is active. This is due to massive current drain and could be a
stalled pump motor or a power wiring error.
TRACTION MOTOR OVERLOADED
The traction motor has been operating in current limit at a low percentage on for a period of time greater than 10
seconds.
PUMP MOTOR OVERLOADED
The pump motor has been operating in current limit at a low percentage on for a period of time greater than 10 sec-
onds.
TRACTION CURRENT AT ZERO - CHECK SHUNT WIRING
Traction current measurement is at zero. This is probably due to an open-circuit between the current measurement
shunt and the power module.
TRACTION POINT A HIGH - CHECK POWER CIRCUITS
Traction point A is near battery supply when neither direction contactor is energized and the traction MOSFETs are
off. This could be due to a welded direction contactor or a power wiring error.
TRACTION POINT A LOW - CHECK POWER CIRCUITS
Traction point A is near 0V when neither direction contactor is energized and the traction MOSFETs are off. This
could be due to a power wiring error.
