9/9
Flash code 9/9 indicates problems with the controller.
POWER MODULE FAILURE: CONTACTOR DRIVE CODE 1
A contactor remained energized when turned off.
POWER MODULE FAILURE: HWFS CODE 2
The hardware fail-safe tests did not complete because traction point A is not safe, or the hardware fail-safe
is permanently tripped.
POWER MODULE FAILURE: HWFS CODE 3
The hardware fail-safe tests did not complete because a contactor was energized when all should be turned
off
POWER MODULE FAILURE: HWFS CODE 4
The hardware fail-safe tests did not complete because the hardware fail-safe tripped immediately when the
traction MOSFETs were turned on.
POWER MODULE FAILURE: HWFS CODE 10
The hardware fail-safe tests failed because the hardware fail-safe did not trip within the allowed test time.
POWER MODULE FAILURE: HWFS CODE 11
The hardware fail-safe tests failed because the hardware fail-safe tripped too slowly.
POWER MODULE FAILURE: HWFS CODE 12
The hardware fail-safe tests failed because the hardware fail-safe tripped too quickly.
POWER MODULE FAILURE: HWFS CODE 13
The hardware fail-safe tests failed because the hardware fail-safe remained tripped when the traction MOS-
FETs were turned off.
POWER MODULE FAILURE: HWFS CODE 14
The hardware fail-safe tests failed because the line contactor could still be energized when the hardware
fail-safe was tripped
POWER MODULE FAILURE: HWFS CODE 15
The hardware fail-safe tests failed because the contactor drive fail-safe did not trip within the allowed test
time.
POWER MODULE FAILURE: HWFS CODE 16
The hardware fail-safe tests failed because the contactor drive fail-safe tripped too slowly.
POWER MODULE FAILURE: HWFS CODE 17
The hardware fail-safe tests failed because the contactor drive fail-safe tripped too quickly.
POWER MODULE FAILURE: HWFS TEST STALLED
The hardware fail-safe tests did not complete, but no reason can be determined.
POWER MODULE FAILURE: 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 controller is shut down.
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
