We're told the SCRAM people got the report sometime between Sunday night and Monday morning -- after Lindsay attended the MTV Movie Awards.
There are reports a SCRAM alarm went off ... not true. We spoke with SCRAM officials who tell us there is no alarm, no light that goes off. SCRAM gets notified by a data download.
As for what triggered the download, we're told it could be a positive alcohol reading or a cut strap. SCRAM would also receive a download if Lindsay didn't get home at a prescribed time ... when she needs to be near the base station.
Whatever the reason, we're told the SCRAM report is going to the judge.
UPDATE: Sources close to Lindsay tell TMZ LiLo didn't drink during the MTV after party.
