9/9
Flash code 9/9 indicates problems with the controller.
POWER MODULE FAI LURE: CONTACTOR DRIVE CODE 1
A contactor remained energized when turned off.
POWER MODULE FAILURE: HWFS CODE 2
The hardware failsafe tests did not complete because traction point A is not safe, or the hardware failsafe is
permanently tripped.
POWER MODULE FAILURE: HWFS CODE 3
The hardwa re fai lsafe tests did no t co m plete beca use a c ontacto r wa s energ ized w hen all sho uld be turn ed
off
POWER MODULE FAILURE: HWFS CODE 4
The hardware failsafe tests did not complete because the hardware failsafe tr ipped immediately when the
traction MOSFETs were turned on.
POWER MODULE FAILURE: HWFS CODE 10
The hardware failsafe tests failed becaus e the hardware fai lsafe di d not trip within the allowed test time.
POWER MODULE FAILURE: HWFS CODE 11
The hardware fai l safe tes ts fail ed bec au s e the hardw are failsafe tripped too slow ly.
POWER MODULE FAILURE: HWFS CODE 12
The hardw are fai ls afe tes t s failed because the hardw are fai l s afe trip ped too quickly.
POWER MODULE FAILURE: HWFS CODE 13
The hardware failsafe tests failed because the hardware failsafe rem ained tripped when the traction MOS-
FETs were turned off.
POWER MODULE FAILURE: HWFS CODE 14
The hardware fai lsafe tests failed b ecause the line con tactor could still be energized when the h ardwa re fail-
safe was trip ped
POWER MODULE FAILURE: HWFS CODE 15
The hardware failsafe tests failed because the contactor drive failsafe did not trip within the allowed test
time.
POWER MODULE FAILURE: HWFS CODE 16
The hardwar e failsafe tests faile d be cause the contacto r d r ive fails afe tripped too slowly.
POWER MODULE FAILURE: HWFS CODE 17
The hardware failsafe tests failed because the contactor drive failsafe tripped too quickly.
POWER MODULE FAILURE: HWFS TEST STALLED
The hardware failsafe tests did not complete, but no reason can be determined.
POWER MODULE FAI LURE: BAD TEMPERATURE SENSOR
The temperature sensor measurement is invalid, this is probably due to a disconnected wire within the
power module. The possibility of other disconnected wires (which could cause dangerous system function)
means that the co ntro ller is shu t dow n.
POWER MODULE FAILURE: S/C LINE CONTACTOR DRIVER The line contactor energized when the foot-
switch was closed, before it was turned on, this is probably due to a failed driver within the power module,
although it could be due to bad power module wirings
