ATTENTION
Do not open and close the ECU connectors
more than 20 times, otherwise it is required to
change the ECU and the wiring harness. If it is
possible it is recommended to perform the
software loading process as described in Sit-
uation 2 to save connection cycles. For a flaw-
less software loading procedure ensure that
the selected power supply is able to provide
constant voltage.
