2 Years ago the car ran but would die at a stop light intermittently. I checked
the code and it called out high voltage MAFS. So I replaced it and it didn't fix
a thing. I let the car sit for two years and periodically I would start it up
and let it run for a while. Today a friend of mine came over and we went to
start it and nothing I mean nothing. The battery is perfect i.e. new. Here is
what I noted as odd the radio doesn’t turn on, the door locks don’t work. In the
DIC there is battery, security, SES that alternate and illuminate.

So far.... I have conducted a CASE learn and in the procedure the security light on
the DIC is supposed to turn off after ten minutes or so of having the key in the
on/start position. It says ten minutes or so.... I did it over and over and
started over and still can’t get the security light to secure on the
DIC.

I'm completely lost and need help! I can’t afford to take it to the
dealer. It's a 2002 monte ss.
