CAUTION / NOTICE / HINT

NOTICE:
·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

When replacing the telematics transceiver, make sure to replace it with a new one.

·

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

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.
