Action for non-repeatable malfunction

• If the malfunction does not recur, verify the malfunction cause by performing the following actions:

? Verify that a DTC has been recorded in the memory. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT].) (See DIAGNOSTIC ASSIST FUNCTION [CONNECTIVITY MASTER UNIT].)

? 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.

? Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for malfunction or occurrence of any DTCs.

? Inspect the female terminals on the connector of the electric component which is suspected to be the cause of the malfunction for poor connection. (See ELECTRICAL SYSTEM.)

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].) (See DIAGNOSTIC ASSIST FUNCTION [CONNECTIVITY MASTER UNIT].)

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.
