Some customers may experience the master warning light and/or the "In-Vehicle Network Malfunction" warning message in the instrument cluster on with DTC B119F:01, B119F:13 and/or B119F:2B stored when the vehicle position cannot be displayed correctly.

B119F:13 (TCU - TEL antenna No. 1 circuit malfunction)
