―  Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.

DTC Inspection Note

•  DTCs for the entertainment system [with center display] can be verified using the M-MDS or the on-board diagnostic test mode in which the on-board diagnostic function can be launched by operating the commander switch or the center display. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT (TYPE-A)].) (See DIAGNOSTIC ASSIST FUNCTION [CONNECTIVITY MASTER UNIT (TYPE-A) (E)].)

Effects of Non-Genuine, After-market Electrical Components

•  A malfunction may occur due to noise interference from a non-genuine, after-market electrical component.
•  If a non-genuine, after-market electrical component is installed, disconnect the connector or unplug from the 12 V accessory socket and verify that the malfunction recurs. If the malfunction does not recur, it is highly possible that the malfunction is caused by the non-genuine, after-market electrical component.
