Lexus SC warning light and error message

I have a 2000 Lexus SC with a gasoline engine. I'm getting an error message in the speedometer and a warning light. The error memory also has a stored error. It seems to be affecting various systems. I suspect it might be the radar sensor. Has anyone experienced something similar?

Greetings. I had an analogous issue with my previous BMW 5 series. The adaptive cruise control malfunctioned, displaying similar symptoms. Intermittent sensor malfunction is a common culprit with those electronic systems.

Interesting. Was the BMW radar sensor issue also causing multiple system failures, or was it just the cruise control? And what was the fix?

Indeed, the BMW exhibited cascading failures due to the sensor issue; the dynamic stability control was also affected. I recommend a diagnostic assessment at a reputable workshop. In my case, it turned out the sensor was simply obscured and a cleaning resolved it. Proceed with caution.

Thank you for the insight. I'll take it to a workshop for a proper diagnosis. Turns out the sensor was just dirty. Cost me 45€ to get it cleaned. Appreciate the help!
