This article supersedes TSB 10-8-4 to update the vehicle model years, Service Procedure and the Part List. The new SYNC service Microphone kit now includes a voltage filter incorporated into the jumper harness.

ISSUE:

Some customers of 2008-2011 SYNC equipped vehicles may express concern with their call sound quality while using the SYNC microphone, complaints of excessive background noise during a phone call and/or issues with voice recognition accuracy while driving.

ACTION:

Follow the service procedure to correct the condition.

SERVICE PROCEDURE

The following procedure involves updating the Accessory Protocol Interface Module (APIM) software level and installing an external alternate SYNC microphone attached to the headliner.

NOTE:THIS PROCEDURE DOES NOT APPLY TO VEHICLES EQUIPPED WITH HEADLINER MICROPHONE OR DEALER-INSTALLED SYNC SYSTEMS.

Go to Step 2 if the vehicle is already equipped with SYNC 3.0 Traffic and Directions or has already been upgraded to latest available consumer interface processor (CIP) level 9L3T-14D544-AE without E911/VHR, 9L2T-14D544-BE with E911/VHR or later versions. To determine the current APIM software level, Refer to the Professional Technician Society (PTS) website, enter the VIN in OASIS, click the GO button and select the SYNC button.

  1. Reprogram the APIM to CIP software level 9L3T-14D544-AE without E911/VHR, 9L2T-14D544-BE with E911/VHR or later version. For additional information Refer to other SYNC TSB's and WSM, Section 418-01. Service Pack files may also be obtained at www.syncmyride.com.

    When diagnosing a concern related to voice recognition (VR) difficulties, instruct the customer to test VR functionality while the vehicle is parked. If customer concerns are still present, this procedure will not yield an improvement and the service procedure should not be performed. Instead, refer to the SYNC supplement guide and www.syncmyride.com for additional VR tips to assist customer.

    The VR experience can be improved with user training and making improvements to the phone book entries (longer entries make the system more robust). Ensure the customer does not try to speak too loud or slow and remove any objects hanging on the rear view mirror as this will reduce system effectiveness.

    When diagnosing a concern related to call sound quality, expect marginal improvements for calls described as speaking in a tunnel, chamber, etc. Expect substantial improvements for complaints where the call audio seems to drop out intermittently.

    NOTE:THIS REPAIR WILL CHANGE THE APPEARANCE OF THE VEHICLE INTERIOR. REFER TO THE PHOTOGRAPHS FOR THE APPLICABLE VEHICLE LOCATED IN THIS PROCEDURE. DO NOT PERFORM THIS REPAIR WITHOUT CUSTOMER APPROVAL PRIOR TO PROCEEDING WITH MICROPHONE INSTALLATION.

  2. Install SYNC microphone service kit. Installing the kit includes mounting an external microphone directly to the headliner and splicing in a jumper harness to the vehicle's existing wiring harness. The existing SYNC microphone will no longer be functional. The jumper harness is equipped with a voltage filter. The filter will need to be wrapped in soft foam 164-R4901 or flock tape 164-R4903 from the Rotunda squeak and rattle kit 164-R4900 to prevent interior squeak/rattle noise.
    1. Refer to the appropriate vehicle line and microphone illustration(s) below for microphone installation and wire splicing locations. Refer to Wiring Diagram (WD), Section 5-1 for recommended splicing methods.
    2. Ensure the SYNC microphone wires are secure and do not interfere with vehicle operation or functionality.
    3. The microphone is directional. Make sure the microphone is always positioned so wire length is minimized from view. When installing the microphone adjacent to trim, place the microphone as close to trim as possible to help minimize visible wire.

Edge / MKX

  1. Remove the protective backing from the adhesive on the microphone and attach the microphone. (Figure 1)
    • Firmly press the microphone into place.
    • Ensure the microphone is parallel and adjacent to overhead console trim.

Final Test / Service Steps

  1. After splicing/soldering is complete, apply power to the vehicle and confirm the voltage at the jumper inline connector before connecting the microphone.
    • Jumper blue wire equal 12V positive.
    • Jumper black wire equal ground reference.
    • Jumper yellow wire equal microphone return signal circuit less than 1V.
  2. Turn off ignition and attach the microphone connector to the jumper harness connector. Make sure that the connector tabs have locked together after connecting. Reversing this connector would cause a failure of the microphone.
  3. Bundle and tuck the remainder of the microphone cable over the front of the headliner.
