As stated before, the CIM and ISM were both replaced...along with a new FOB programmed. The vehicle started several times post replacement. However, less than a week it is right bak to the same. To me...it seems like something downstream since the SID works fine except when this intermittent pain occurs. A couple questions...are there relays triggered from the CIM/Transponder activation that would affect power to SID? Could the alam module be misfunctioning and cause this?
