CAUTION / NOTICE / HINT

NOTICE:

When replacing the navigation ECU, always replace it with a new one. If a navigation ECU which was installed to another vehicle is used, the following may occur:

·

A communication malfunction DTC may be stored.

·

The navigation ECU may not operate normally.



HINT:

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System.
