2000 Lexus SC400 ProblemsCheck Engine Light Due to EVAP System Failure
Occasionally, the Check Engine Light is illuminated due to failures in the evaporative emission (EVAP) system. Our technicians tell us that proper diagnoses is generally required to confirm the exact fault causing the warning light to come on.
There are reports of intermittent failures with the heating and air conditioning control. The digital display might fail or the control might fail to switch between heater functions.
There are reports of LED problems in the dashboard gauges. The lights burn out, making the gauges difficult to see at night, and require replacement.
