Troubleshooting
7.13
Power Pack Empty
If the power pack is completely empty, the BMS disables the
throttle. You cannot ride the motorcycle until you recharge the
power pack. If the Power Pack does not have a partial charge
after two hours of charging time, contact your dealer. Your
power pack may need to be repaired or replaced.
Power Pack Full (High Power Pack-Voltage)
If the BMS detects that the power pack is already full, it disables
any further charging to prevent damage to the power pack.
This is not an error-condition; it is the result of a successful
charging cycle. There is no self-test flash code which reports
this condition.
During an ordinary charging cycle, when the cells are balanced,
the charger (not the BMS) senses that the power pack is full and
terminates the charging cycle with a “green light.” The BMS
does have a redundant back-up mechanism to prevent
overcharging of the power pack. If the charger fails to terminate
a charging-cycle when the power pack is full, the BMS will
terminate charging automatically to prevent damage.
Power Pack Too Hot
The power pack contains internal temperature sensors. If the
BMS measures excessive internal temperatures, it flashes an
error code and disables the throttle. You cannot ride the
motorcycle until the power pack cools down. Place the
motorcycle in a cool, well-ventilated location and wait a few
minutes before riding again. If the “High Battery Temperature
Status Disable” (42) error code still flashes after the power pack
has had time to cool down, contact your dealer. Your power pack
may need to be repaired or replaced.
Power Pack Unbalanced
The power pack contains many individual cells. The BMS
continuously monitors the cells and tries to keep them all “in
balance” (at the same level-of-charge). If any of the cells are
grossly out-of-balance, the BMS flashes a Power Pack
Unbalanced error code and disables the throttle. You cannot ride
the motorcycle until the problem is resolved.
The solution to the problem is to plug in the charger and allow
the power pack to charge for 72 hours. This allows the BMS to
re-balance the cells in the power pack. If the Power Pack
Unbalanced error code still flashes after the power pack has
spent more than 72 hours charging, contact your dealer. Your
power pack may need to be repaired or replaced.
