  • Operate multiple channels of the audio system in satellite radio mode.

Does the satellite radio system receive multiple channels with normal sound quality?
Yes The system is currently operating correctly. The concern was the result of the ESN and VIN in the customer's SIRIUS file not matching the ESN and VIN received from the vehicle.
No • If the PID reads "Good", "Very Good" or "Excellent" was obtained, CONTACT www.siriusxm.com/refresh and enter the ESN to resend the activation signal.
• If the PID reads "Good", "Very Good" or "Excellent" was not obtained, GO to B6

Loud Popping Noise When Ignition Is Turned On


For wiring diagrams and connector information, refer to Cell 130 of the Wiring Diagrams.


For circuit and connector information, refer to Wiring Diagrams Cell 20.

Normal Operation and Fault Symptoms

The PCM supplies voltage to the ACM on the start signal circuit when the ignition is in the START position. When voltage is supplied to the ACM, the audio output is muted to prevent pops from being heard through the speakers. An open in the circuit between splice S212 and the ACM may cause pops in the speakers.

REFER TO ACM.

A short to ground or a short to voltage in the circuit 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 DTC is set.

The PCM supplies voltage to the ACM on the start signal circuit when the ignition is in the START position. When voltage is supplied to the ACM, the audio output is muted to prevent pops from being heard through the speakers. A short to voltage in this circuit causes a constant mute of the ACM output.

  • Using the diagnostic scan tool, view the APIM parameter identifications (PIDs).
  • Monitor the paired Bluetooth device PID (BT_PAIR) and the connected Bluetooth device PID (BT_CONN).

Do both Parameter Identifications (PIDs) read "Yes"?
Yes GO to S2
No GO to S5
S2 PERFORM A MASTER RESET AND RECHECK THE CUSTOMER DEVICE
  • NOTE: Performing a master reset returns all configuration preferences to factory settings, erases the phonebook and call history, deletes all Bluetooth devices paired to the SYNC® system, and removes any Wi-Fi network connections (cancelling any system update that is downloading or installing). For vehicles with navigation, customer-saved destinations (home, favorites and recent) are erased. Perform the master reset. For information on how to perform a master reset, refer to Master Reset in the Owner's Literature.
  • Pair and connect the customer's Bluetooth device to the APIM. For information on the pairing process, refer to the Owner's Literature.
  • Using the diagnostic scan tool, view the APIM parameter identifications (PIDs).
  • Monitor the paired Bluetooth device PID (BT_PAIR) and the connected Bluetooth device PID (BT_CONN).

Do both Parameter Identifications (PIDs) read "Yes"?
Yes If the individual Bluetooth device function, such as text messaging, Bluetooth media playback or controls, phonebook download, call history or call waiting, is not working , GO to S3.
If the individual Bluetooth device functions, such as text messaging, Bluetooth media playback or controls, phonebook download, call history or call waiting, are working correctly , the system is currently operating correctly. REVIEW the pairing process with the customer.
No If the customer's device does not connect or pair, GO to S4.
S3 CHECK THE NON-WORKING BLUETOOTH DEVICE FUNCTION
  • Review the list of compatible devices and determine if the non-working Bluetooth device function is supported and compatible. Refer to owner.ford.com/how-tos/sync-technology/all/phone-setup/phones-compatible-with-sync.html#?syncGen=sync3&country=us

Is the non-working Bluetooth device function supported and compatible?
Yes GO to S4
No This is normal operation for unsupported or incompatible Bluetooth functions, which will not be available through the SYNC® system.
S4 CHECK THE CUSTOMER DEVICE
  • Advise the customer to turn the device off and back on to perform a simple reboot.
  • If necessary, advise the customer to remove the battery (if possible) and reinstall it to perform a full reboot.
  • If necessary, advise the customer to check their device for available updates.
  • If necessary, advise the customer to delete "SYNC" from the Bluetooth device menu before attempting to re-pair, and reconnect the Bluetooth device to the APIM.
  • If necessary, the customer can also perform a Master Reset, General Reset, or Factory Data Reset on their device following the manufacturer's instructions in the device owner's manual and/or website.

Is the concern still present?
Yes The fault is related to the customer device.
No The system is currently operating correctly. ADVISE the customer to review the list of compatible devices. Refer to owner.ford.com/how-tos/sync-technology/all/phone-setup/phones-compatible-with-sync.html#?syncGen=sync3&country=us.
S5 CHECK APIM (SYNC MODULE) OPERATION
  • Ignition OFF.

  • Repair:
    • Corrosion (clean the module terminals or install new connectors or terminals)
    • Damaged or bent terminals (install new terminals or pins)
    • Backed-out pins (install new pins as necessary)
  • Reconnect the APIM connector. Make sure it is properly seated and latched.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, discontinue this test and follow the TSB instructions. If no TSBs apply to this concern, PERFORM the APIM hardware test.
