Diagnosis And Testing: Audio

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

Any diagnosis of the Audio system should begin with the use of scan tool. Check for any Diagnostic Trouble Codes (DTCs) . If there are any DTCs, perform the appropriate diagnostic procedure(s) before proceeding.

For complete circuit diagrams, refer to the appropriate wiring information.

WARNING:

Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable. Wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.

AUDIO SYSTEM DIAGNOSIS

CONDITION	POSSIBLE CAUSE	CORRECTION
RADIO INOPERATIVE	1. Fuse inoperative.	Check radio fuses in integrated power module (IPM). Replace fuses, if required.
	2. Open Wiring.	Perform the "No Response From Radio" test. Refer to DIAGNOSIS AND TESTING .
NO AUDIO - BUT RADIO LIGHTS UP	1. Antenna problem.	Perform the "Poor Or No AM/FM Audio Reception" test. Refer to DIAGNOSIS AND TESTING .
	2. Amplifier inoperative.	Perform the No Response From Amp test. Refer to DIAGNOSIS AND TESTING .
NO RADIO DISPLAY	1. Fuse inoperative.	Check radio fuses. Replace fuses, if required.
	2. Radio connector damaged.	Check for loose or corroded radio connector. Repair, if required.
	3. Wiring damaged.	Perform the No Response From Radio test. Refer to DIAGNOSIS AND TESTING .
	4. Ground damaged.	Check for continuity between the radio chassis and a known good ground. There should be continuity. Repair ground, if required.
	5. Radio inoperative.	Perform the "No Response From Radio" test. Refer to DIAGNOSIS AND TESTING .
POOR AM/FM RADIO RECEPTION	1. Antenna inoperative	Perform the "Poor Or No AM/FM Audio Reception" test. Refer to DIAGNOSIS AND TESTING .
	2. Radio ground damaged.	Check for continuity between the radio chassis and a known good ground. There should be continuity. Repair ground, if required.
	3. Radio inoperative.	Refer to the appropriate Diagnostic Service Information. Refer to DIAGNOSIS AND TESTING or DIAGNOSIS AND TESTING .
POOR SDAR RADIO RECEPTION	1. SDAR Antenna Inoperative.	Perform the "Poor Or No Satellite Audio Reception" test. Refer to DIAGNOSIS AND TESTING .
	2. Antenna Cable Problem.	Perform the "Poor Or No Satellite Audio Reception" test. Refer to DIAGNOSIS AND TESTING .
NO MEMORY	1. Fuse inoperative.	Check ignition-off draw fuse. Replace fuse, if required.
	2. Radio connector damaged.	Check for loose or corroded radio connector. Repair, if required.
	3. Wiring damaged.	Perform the "No Response From Radio" test. Refer to DIAGNOSIS AND TESTING .
	4. Ground damaged.	Check for continuity between the radio chassis and a known good ground. There should be continuity. Repair ground, if required.
	5. Radio inoperative.	Perform the "No Response From Radio" test. Refer to DIAGNOSIS AND TESTING .
SOUND DISTORTION (VIBRATION FROM SPEAKER AREA, BUZZING - HUMMING	1. Door trim panel loose or missing fasteners.	Inspect door trim panel and correct as necessary. Replace any missing fasteners.
	2. Water shield loose or misaligned.	Inspect water shield and adjust as required.
	3. Items placed in door trim panel map pockets vibrating or moving from side to side.	Remove items from door trim panel. Ensure that vibration is no longer present.
NO COMPACT DISC OPERATION	1. CD damaged.	Insert known good CD and test operation. Avoid the use of "home made" CD's with adhesive labels. The labels may cause disc to become jammed in the radio.
	2. Foreign material on CD.	Clean CD and test operation.
	3. Condensation on CD or optics.	Allow temperature of vehicle interior to stabilize and test operation.
	4. Radio inoperative.	Exchange or replace radio, if required.
