Technician’s notes:

The Lexus SC400 is a bullet proof grand tourer but as our vehicles age, components such as computers can leave us scratching our head due to erratic symptoms. This computer commonly suffers from capacitor failure and corrosion.

When capacitors age they basically dry out keeping the computer from functioning properly and causing intermittent problems.

As rare as these units are becoming our service is a great place to start when diagnosing a no start issue and since age is a catalyst to capacitor failure, our service is a great preventative measure against further damage.

Other acronyms commonly used for the Engine Computer: ECU Engine Control Unit – ECM Engine Control Module – BCM Body Control Module – PCM Power Control Module
