Diagnosis And Testing: Audio
Any diagnosis of the Audio system should begin with duplicating the customer concern (verify the problem), include checking for applicable Technical Service Bulletins (TSB), Star Online Publications, software updates and the use of a diagnostic scan tool. Check for any Diagnostic Trouble Code (DTC) data. If a DTC is found, refer to DTC INDEX (1 OF 2) and/or DTC INDEX (2 OF 2) and perform the appropriate diagnostic procedure before proceeding in this section. Refer to the appropriate wiring information.
