Here is what I wrote for someone.

To communicate with the engine ECU and reset the "ENGINE" light, you need to
have you need to have the "Options" set properly. Here is what is working
for me.

Under "Options" click on "Gateway". In the protocol selection you need to
have selected the following options:
ISO-9141-2
Speed=60, byte=10, multi=20
timeouts=5
auto reconnect
clear cache on connection
Under "Options" click on "filter". In the protocol selection you need to
have selected the following options:
Address Accept Filter=17


To communicate with the instrument cluster and to reset the Service Light,
you need to change the following option:
Address Accept Filter=All
Then close the program and restart it. You should not attempt to connect to
the engine ECU (once connected to the engine ECU you will not be able to
reset the service light). To reset the SERVICE light you select first the
"STATUS" tab and then click on "Enhanced" on the top menu.
