Ask a Lexus 300 to run at idle speed and the engine failure lights on the dashboard, and both the TRC and VSC lights. By looking at the driver's manual, knowing the meaning of the two lights is the failure of the active traction control system and the vehicle stability control system. But I do not know how to start to solve.
     Answer According to the situation you mentioned, I am very familiar with this fault phenomenon, and I analyze your Lexus 300 should be produced between October 2002 and October 2003. The engine fault lights, the TRC and VSC lights should be lit at the same time only if the engine is faulty. The TRC and VSC systems only light up the engine when the fault is detected. As to what the engine is faulty, it is recommended that you immediately to Toyota's after-sales service shop to determine whether it is a typical failure.
