Component Parts: TCU

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

TCU is installed on the lower right of the instrument panel.
A radio communication terminal is built into the unit, and data is sent and received in SMS and packet communication with the NISSAN CARWINGS data center through the TEL antenna.
VIN information necessary for the Telematics service is memorized.
