An accessory isn't
working, but the
Diagnostics window
isn't showing an
overload for that
circuit.
1. Make sure all power circuit plugs are securely connected.
2. Open the ezCAN Diagnostics window.
3. Under Output Circuit Test, click-and-drag the slider for
the affected circuit.
 The accessory connected to the circuit should
respond accordingly.
4. If the accessory does not respond, check that the
software configuration for the circuit is correct.
5. If the accessory still does not respond, connect it to
another ezCAN power circuit, and repeat steps 3 and 4
above.
The ezCAN software
interface shows a
green message
notification (below).
The combined maximum current limit for the four power
circuits has been set at more than 30 Amps.
View the average and peak current draw for each power
circuit since the ignition switch was last turned on in the
Output Circuits section of the ezCAN Diagnostics window.
This may help if you need to fine-tune the fuse trip limits.
Re-calculate the maximum current draw for all circuits as
shown in Making the correct fuse selection. If needed,
reduce the fuse trip limit on one or more circuits.
The ezCAN software
interface shows an
orange message
notification (below).
 The ezCAN may not be connected to battery power.
 The motorcycle's battery voltage may be too low.
 The motorcycle's CAN bus voltage may be too low.
 CAN data may be missing, or is not being detected.
Check the following items:
 Make sure the motorcycle’s ignition is switched ON.
 Check the Messages section of the ezCAN Diagnostics
window. If you see a message that data is not being
received, make sure the motorcycle’s kill switch is in the
RUN position.
 Make sure the ezCAN is receiving acceptable battery
voltage. If your motorcycle does not have a voltmeter,
check the Battery Voltage value in the System section
of the ezCAN Diagnostics window. This value should be
more than 11 volts with the ignition switch ON and
engine OFF, and approximately 14 volts if the engine is
running.
 Check the CAN-bus data value in the System section of
the ezCAN Diagnostics window. The value should be
Active. If the value is Inactive, make sure the ezCAN is
securely connected to the correct CAN-bus connector on
the motorcycle.
 Make sure the ezCAN’s battery connections are secure.
 Make sure the ezCAN main fuse is not blown.
 If the ezCAN main fuse is blown, check for short circuits
along the ezCAN wiring and accessory wiring. Replace
the main fuse only with one of the same type and 30
Amp rating.
IMPORTANT
If all power outputs are not operated
simultaneously, this may be an acceptable
condition.
However, note that the main fuse may blow
if the ezCAN draws more than 30 Amps.
