Troubleshooting Chart
Possible Cause(s)
1. Temperature information is
not accurate.
2. Controller is operating in an
extreme environment.
3. Excessive load on vehicle.
4. Improper mounting of
controller.
1. Battery Menu parameters are
misadjusted.
2. Non-controller system drain
on battery.
3. Battery resistance too high.
4. Battery disconnected while
driving.
5. See Monitor menu » Battery:
Capacitor Voltage.
6. Blown B+ fuse or main
contactor did not close.
1. Battery menu parameters are
misadjusted.
2. Battery resistance too high
for given regen current.
3. Battery disconnected while
regen braking.
1. See Monitor menu »
Controller: Temperature.
2. Controller is performance-
limited at this temperature.
3. Controller is operating in an
extreme environment.
4. Excessive load on vehicle.
5. Improper mounting of
