HINT:
·

The TOYOTA Connect system performs communication between devices via USB communication. If a malfunction such as a short in a communication line, short to +B or short to ground occurs in the USB circuit, communication will stop and the TOYOTA Connect system will not operate correctly.

·

This DTC may be stored due to environmental reasons such as electrical noise or interference.



PROCEDURE
