Pinpoint Tests

Poor AM / FM Reception Or Continuous Seek/Scan

Refer to Wiring Diagrams Cell 130 for schematic and connector information.

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Information and Entertainment System - System Operation and Component Description (415-00A Information and Entertainment System - General Information - Vehicles With: AM/FM/CD/SYNC, Description and Operation).

The RDS function allows the vehicle operator to choose which genre (category) of music to listen to. When the SCAN button is pressed, the ACM only stops at channels falling within the selected category. If no channel in the selected category is found, the ACM continues to scan without stopping. This can appear to be a reception issue, but it is actually due to the audio system settings.

A Loud Popping Sound Is Heard When Cycling The Ignition

Refer to Wiring Diagrams Cell 130 for schematic and connector information.

Refer to Wiring Diagrams Cell 20 for schematic and connector information.

Normal Operation and Fault Conditions

The PCM provides voltage to the ACM on the start signal circuit when the ignition is in the START position. When the voltage is received by the ACM , the audio signal output is muted to prevent voltage spikes from producing popping noises through the speakers. An open on the circuit between splice S212 and the ACM could cause voltage spikes to produce popping noises through the speakers.

Poor Sound Quality Or Distorted Sound From One Or More Speakers (Not All Speakers)

Normal Operation and Fault Conditions

The ACM sends audio signals to the speakers in the form of AC voltage, resulting in clear audio output.

Possible Sources

Loose component fasteners
Loose door handle, lock, and other trim panel components and fasteners
Loose items in storage areas
Loose speaker grilles
Loose wire harnesses or wire harness fasteners
Speaker(s)
Water shield bonding and placement

Visual Inspection and Diagnostic Pre-checks

Inspect the suspect area for any possible rattle conditions such as:

Any storage compartments including cup holders (if equipped)
Door map pockets for contents that can rattle (if equipped)
Door pull cup attachments (if equipped)
Door switch bezels (if equipped)
Package tray (if equipped)
Speaker grilles
Trim panels and fasteners

PINPOINT TEST D: POOR SOUND QUALITY OR DISTORTED SOUND FROM ONE OR MORE SPEAKERS (NOT ALL SPEAKERS)

D1 ISOLATE THE ZONE

Operate the audio system using digital media (CD , MP3, etc.).

Using the audio system fade and balance feature, adjust the audio sound to each of the four zones (left front, right front, left rear and right rear) of the vehicle to isolate the poor sound quality.

Locate and apply pressure to the trim panel(s) around the poor sound quality area in question.

Does applying pressure to a trim panel reduce or eliminate the audible noise?

Yes

REPAIR or REPLACE the trim panel as needed.

GO to D2

D2 REMOVE AND INSPECT BEHIND/UNDERNEATH THE SUSPECT TRIM PANEL(S)

Remove the trim panel to access the suspect speaker.

Operate the audio system using digital media (CD , MP3, etc.).

Validate where the poor sound quality area is located.

Check:
- Trim panel for loose components around the speaker area such as the speaker grille.
- Trim panel joining components for missing or broken pieces.
- Lock and handle mechanical parts for correct attachment.
- Wire harnesses for correct routing.
- Wire harness fasteners for correct attachment.
- Water shield for correct placement (speaker air path not blocked).
- Water shield for correct bonding to sheet metal.
- Storage areas for loose items.
- All child safety belt anchors (if equipped).
- All safety belt retractors.
- All speaker bracket fasteners and other fasteners are secured and tightened to specified torque.

Was the source of the noise located?

Yes

REPAIR or REPLACE any loose or broken component or fastener as needed.

GO to D3

D3 CHECK THE SUSPECT SPEAKER FOR WATER INTRUSION

Inspect for watermarks.

Check the:
- Cone
- Magnet
- Basket

Are any watermarks present on the speaker?

Yes

VERIFY the water shield is in the correct location, REPAIR or REPLACE any trim, door, or speaker seal as required.
DRY the speaker in question and TEST the system for normal operation.

GO to D4

D4 ISOLATE SPEAKER TO VERIFY NOISE

Remove the suspect speaker from its location and leave the speaker connected to the harness.

Hold the speaker away from any trim panel(s) and make sure the speaker is isolated from contact.

Operate the audio system using digital media (CD , MP3, etc.).

Is the noise still present in the suspect speaker?

Yes

INSTALL a new speaker for the one in question.

No	LOCATE the source of the noise and REPAIR as needed.

No Sound From All Speakers

Refer to Wiring Diagrams Cell 130 for schematic and connector information.

Normal Operation and Fault Conditions

A short to ground or short to voltage in the circuitry to one of the speakers may cause multiple speakers to lose sound due to the built-in overload protection feature of the ACM . In this case, a speaker fault DTC sets.

The PCM provides voltage to the ACM on the start signal circuit when the ignition is in the START position. When the voltage is received by the ACM , the audio signal output is muted to prevent voltage spikes from producing popping noises through the speakers. A short to voltage on this circuit causes the ACM output to be muted continuously.
