Ford Taurus Service Manual: General Procedures

Audio Control Module (ACM) Self-Diagnostic Mode

NOTE: If the ACM is completely inoperative (does not power up), the part number decal on the ACM chassis can be used to attain the ACM part number.

  1. Turn the ACM on.
  1. Operate the audio system in radio tuner (AM/FM) mode.
  1. Press and hold the eject button, and within 1 second, press the seek up button until the speaker walk-around test begins.
    • The display indicates each speaker as it is tested.
  1. NOTE: If the speaker walk test is the only test required, this procedure can be stopped after Step 3 by turning the ACM off or by selecting exit using the audio system control buttons.

    Once the speaker walk-around test is complete, the following information is available through the "BEZEL DIAGNOSTICS" menu using the audio system control buttons:

    NOTE: The AHU Diagnostics refers to the ACM and EFP Diagnostics refers to the FCIM.

  1. To exit the self-diagnostic mode, turn the ACM off.

Accessory Protocol Interface Module (APIM) Reset

NOTE: Carrying out an APIM Reset consists of a battery disconnect and a SYNC system Master Reset.

NOTE: NOTE: This procedure will clear all CMDTCs. The DTCs must be recorded now if other (non SYNC) diagnoses are to be performed after this procedure.

  1. Remove any devices connected to the USB port(s), audio input jack (if equipped), or media hub (if equipped).
  1. NOTE: After the APIM reset procedure has been completed the customer should be advised to reset their device following the manufacturer's instructions. Refer to the device's owner's manual and/or website for information on how to perform a Manual / Master Reset or Clear. Devices can be powered off and back on for a simple re-boot. In some cases the device's battery may also need to be removed and re-installed to complete a re-boot. In addition, cell phones may need to have SYNC deleted from the Bluetooth menu prior to re-pairing the phone to the SYNC system. Customer devices may affect the operation of SYNC and this should be understood to prevent unnecessary diagnosis or repairs to the system.

    Disconnect the negative battery cable for 1 minute, then reconnect it. Refer to Section 414-01.

  1. NOTE: Performing a Master Reset returns all preference settings to the factory defaults, erases all the phone book and call histories, and deletes any devices paired with the SYNC system. On vehicles equipped MyFord Touch or MyLincoln Touch with navigation, the customer's saved destination points (home address and points of interest) and preferences will also be lost with a Master Reset.

    Carry out a SYNC system Master Reset. Refer to the owner's literature

  1. Verify system function using the Multi-Media Interface Tester 105-00120, to test the audio output for the audio input jack/socket (if equipped), USB port(s), and Bluetooth. If equipped, use the RCA Adapter 105-00121 to test the audio output for the RCA jacks.
  1. If a concern is still present return to the Symptom Charts.

Accessory Protocol Interface Module (APIM) Programming

Special Tool(s)

Ford Taurus. Audio Systems

Accessory Protocol Interface Module (APIM) Programming Using the Integrated Diagnostic System (IDS)

NOTE:

  • If a new APIM is being installed, install a new APIM before carrying out the following procedure. Refer to Accessory Protocol Interface Module (APIM).
  • When performing the programming procedures, follow the scan tool on-screen directions.
  • Make sure the battery is fully charged before performing the programming steps.
  • A hardwired internet connection is strongly recommended when programming.
  • If unable to complete programming because operation stops or errors are received, internet browser settings may need to be configured. From the on-line OASIS tab, select the "Service Tips" tab, then select "SYNC Software Programming" under "Job Aids".

NOTE:

  • For APIM flash programming:
    • The scan tool and a SYNC RE-FLASH KIT (CCMSYNC-KIT or equivalent) are required.
    • The flash procedure deletes any paired phones that were in the SYNC system.
    • The file for the flash needs to be downloaded from the online database. Allow for extra time for the file to download. The files are approximately 80 megabyte.
  1. NOTE: The IDS program must be closed before attempting to program the APIM.

    Open a session for the vehicle from the technician service publication web site, and run OASIS using "Read VIN and DTC's".

  1. From the OASIS tab, select the "SYNC" button.
  1. There are 3 available options for APIM programming:
    • Standard (latest version of current software and applications): Use this option to update the APIM to the latest software level.
    • Custom (show what's available, and let me choose): Use this option to show all the available options that can be programmed, or if a TSB directs for specific software version to be programmed.
    • Module Replacement (restore software for newly installed hardware): Use this option when the APIM has been replaced.
  1. After selecting 1 of the 3 options (Standard, Custom or Module Replacement), click the "Read SYNC" button to verify the current APIM, VIP and CIP software levels.
    • The versions are compared to a online database. After the comparison, the available software is displayed.
  1. NOTE: Do not disconnect the VCM or the USB cable during APIM programming.

    When carrying out the programming procedures, follow the scan tool on-screen directions.

    NOTE: If unable to complete programming because operation stops or errors are received, interned browser settings may need to be configured. From the on-line OASIS tab, select the "Service Tips" tab, then select "SYNC Software Programming" under "Job Aids".

    Select the "Program SYNC" button to begin the APIM programming process.
  1. Follow the scan tool on-screen directions for APIM programming.
    • After programming is complete the scan tool displays "Programming has been completed successfully."

Satellite Radio Receiver Electronic Serial Number (ESN) Retrieval

NOTE: If the ACM is completely inoperative (does not power up), the part number decal on the ACM chassis can be used to attain the ESN part number.

  1. Turn the ACM on.
  1. Using the audio system control buttons, select Menu.
  1. Using the audio system control buttons, select SIRIUS options.
