Lexus RX350 AWD system check and warning lights for Check Engine, VSC, and TRAC with codes C1201 and P0352 on Lexus RX350

Some Lexus RX350 owners report experiencing issues when the "Check AWD System" light illuminates, indicating potential problems with the All-Wheel Drive system that could compromise safety while driving. These owners also note that the VSC (Vehicle Stability Control) and TRAC (Traction Control) warning lights may activate, particularly if the Check Engine light is on. Specific trouble codes, such as C1201, often relate to malfunctions in the Engine Control Module (ECM) or ABS control module, while code P0352 points to issues with the ignition coil B primary/secondary circuit. To resolve these warnings, some owners recommend performing a diagnostic scan to identify the underlying issues, seeking a professional inspection to address the codes, and ensuring regular vehicle maintenance to prevent future problems. They emphasize the importance of addressing the root cause of the Check Engine light to restore functionality to the AWD and TRAC systems effectively.
