A word about network communication protocols. The ECU needs
to have access to the router via a lan IP address. The ECU will only
search for and obtain a Dynamic Host Configuration Protocol (DHCP)
IP address during its powering up sequence.
For example, the LCD screen on the front of the ECU displays an lan
IP address such as “192.168.1.101” if the connection to the router is
successful (the IP address will vary based on router supplier, so check
with the user manual for specifics). If, however, the LCD displays
“192.168.131.228”, the ECU-router connection has not been successful,
in which case you’ll need to check all of the cabling connections and
reboot the ECU by removing the power cable for a few seconds and
reconnecting.
