COMMON PROBLEMS

Weak vehicle battery
Before using the software to communicate with the
vehicle, make sure the battery is fully charged. A low
battery can allow the ECU power relay may drop
power to the ECU which will stop any communication
between the PC and ECU.
EMS not powered-up
In order to use the tool, power to the engine man-
agement system must be ON. This is required
because the software tool "communicates" with the
ECU. If the engine management circuits are OFF, the
software cannot receive or transmit any information
to the ECU.
Activating or turning on the engine management
system differs between vehicle types (ATV or Motor-
cycle). But, in both types, if the vehicle ECU senses
no activity (no engine start or communications
between the PC and ECU) for two minutes, it will
drop the signal voltage to the EMS power relay
shutting down power to itself. If you attempt to send
or receive data from the ECU while it is "powered-
down", the "Failed to Unlock System 125" message
will display.
When this happens, the all power to the engine
management system is shut off until the engine start
button is pressed again.
