Pinpoint Tests

 

Pinpoint Test A: Poor Reception — AM/FM

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation and Fault Conditions

Refer to AM/FM radio in Information and Entertainment System .

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 may appear to be a reception issue, but it is actually due to the customer setting.

Pinpoint Test B: The Satellite Radio Is Inoperative, Has Poor Reception Or No Sound

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation and Fault Conditions

Digital signals are received by the satellite radio antenna and sent to the Audio Front Control Module (ACM), as the satellite radio receiver is built into the ACM .

When a satellite radio subscription is activated, the ESN of the built into satellite receiver is associated with the VIN . As a result, the ACM cannot be swapped from one vehicle to another.

Obstructions to the antenna line of sight can affect reception, but this is considered normal operation. Possible obstructions include hills, tall buildings, tunnels, and being parked inside a garage. Be sure the vehicle is in a clear area, free of obstructions, before testing satellite radio reception.



 DTC Fault Trigger Conditions

DTC Description Fault Trigger Conditions
B1A89:11 Satellite Antenna: Circuit Short To Ground Set by the ACM when a short to ground is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand.
B1A89:13 Satellite Antenna: Circuit Open Set by the ACM when an open is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand.
U3000:96 Control Module: Component Internal Failure Set by the ACM when a fault is detected in the internal satellite radio receiver. This results in complete loss of satellite radio functionality.

Visual Inspection and Diagnostic Pre-checks

Verify that the satellite radio subscription has not expired.

Pinpoint Test C: No Sound From All Speakers

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation and Fault Conditions

When the key is in START, the ACM receives voltage on the START signal circuit. The ACM then mutes the speaker output to prevent voltage spikes from producing a popping noise through the speakers. However, a short to voltage on this circuit causes the ACM output to be continuously muted.

If a speaker circuit fault DTC is set in the ACM , the cause of the concern is a short to ground or short to voltage in an individual speaker circuit, which has caused the ACM overload protection to activate. If a speaker circuit fault DTC is present, refer to DTC Charts in this section.
