Having repaired the illumination model are you certain the SKREEM is in need of repair. Have you disconnected the battery for a minute and then tried to start the car? What exactly happens. Does the car turn over and not start, or does it do nothing at all when you turn the ignition switch or perhaps it does start but only briefly and then die right away twice before nothing happens when turning your key?? The repair to the above problems all require a different approach and not necessarily the SKREEM. What exactly is your problem now that the new module is installed.
I personally do not like the SKREEM delete as it seems to be a butcher job to the cars design. Repairing the SKREEM is not any more of a job than deleting it.
