Lexus CHECK PCS SYSTEM error message is a global problem

UPDATE: NO LONGER TRACKING THESE INCIDENTS OR PROVIDING ASSISTANCE. Over the last several years I've had several emails from people around the world interested in how to properly diagnose their "Check PCS" problem. Most people have indicated that they had to replace the ECU, others seemed to have an intermittent problem with the power feed (alternator) or condition of the plexiglass cover. Regardless, this issue has been reported by owners all Lexus vehicles with the Denso Pre-Collision System offered in several models including: Lexus LS430, Lexus IS250, and others. If equipped with PCS, anticipate a problem at some point.

Check out the map of incidents reported to me by people around the world with similar problems.
