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

DTC Inspection Note
• There are two methods of DTC inspection for the audio system: The on-board diagnostic test mode by operating the audio unit to activate the on-board diagnostic function, and using the M-MDS. (See DTC INSPECTION [AUDIO].)
Caution
• Because there are DTCs which are not available in the on-board diagnostic test mode, the displayed DTC may differ depending on whether the on-board diagnostic test mode or the M-MDS is used. If there is a malfunction in the audio system even though a DTC is not displayed in the on-board diagnostic test mode, perform the DTC inspection using the M-MDS. (See DTC TABLE [AUDIO].)
