Error code
Remedies
Fault in power cut-
off switch:
LEDs of assistance
levels 1 and 3 light
up
Switch off the system. Check the mechani-
cal function of the power cut-off lever
switch. Check whether the brake levers re-
turn completely to their starting position
when released.
If the problem persists: Disconnect both
power cut-off levers at the controller and
check the function of the system again. If
the system works, one or both of the two
brake levers is defective and must be re-
placed.
If the system still does not work, check the
function of the controller.
Communication er-
ror:
All LEDs of the as-
sistance levels light
up
Replace the display.
If the problem persists, install the original
display again and replace the battery.
ON/OFF switch:
All LEDs of the as-
sistance levels and
the battery charge
indicator light up
Check whether the ON/OFF switch is OK.
If the problem persists, the display will have
to be replaced.
Minus button:
All LEDs of the bat-
tery charge indica-
tor light up
Check whether the minus key is OK.
If the problem persists, the display will have
to be replaced.
Program error:
All LEDs of the as-
sistance levels and
the battery charge
indicator flash
In this case you have to determine which
electronic component could be defective by
a process of elimination.
