October 5, 2011.

Supersedes Technical DIAGNOSIS AND REPAIR Group 91 number 11 - 97 dated July 15, 2011 for reasons listed below.

Affected Vehicles

Condition

Customer complains of one of the following:

^ During a Bluetooth call the other party has trouble hearing them.

^ Voice recognition accuracy is poor.

Technical Background

This TSB provides guidelines for testing microphones in a vehicle.

Production Solution

Not Applicable.

Service

1. Investigate GFF to determine if a fault is stored for microphone operation in address words 56, 5F, 67, or 77 depending on vehicle and equipment

levels.

2. If a fault is stored in GFF, proceed with the test plan outlined in the scan tool. If there is no DTC stored, proceed to step 3.

3. Verify the complaint by using one of the following methods:

a. Pair a known good compatible Bluetooth phone to the system, and place a call to a landline contact. Place the call in the same conditions as the

customer concern (driving, stationary, A/C on, etc.).

If the call quality for the other person is clear and without distortion, then the microphones are OK and should not be replaced. If noise or

distortion is heard, then proceed to step 4.

b. Create a directory contact and then a voice tag for that entry. Create the voice tag in the same conditions as the customer concern (driving,

stationary, A/C on, etc.). Playback the entry and verify it is clear and without distortion.

If the entry sounds clear, then the microphones are OK and should not be replaced. If noise or distortion is heard, then proceed to step 4.

4. Check the microphones for mechanical defects:

324

a. Remove the roof module and verify the microphones are securely seated in the roof module by pressing on them. For 2012+ C7 & D4 vehicles,

remove the microphones and inspect the rubber seal around the edge of the microphone. Verify it is not torn or broken. If it is damaged, replace

the microphone. For vehicles equipped with integrated seat belt microphones, please reference TSB 2026851, 91 Belt Microphone Overview.

Note:

When installing microphones back into the roof module, make sure the microphones are installed straight into the cavity. Installing them at any other

angle can cause damage to the microphone and/or seal.

b. Inspect the microphone wiring and verify it is securely fastened in place and that there is no visible sign of damage.

5. Check the microphones for electrical defects:

a. Disconnect the microphones and verify the voltage coming from the module is 8V +/- 10%.

b. Disconnect the microphone cable at the control module and verify that the voltage on the wiring to the microphones is 0V.

c. If voltage is present in step a. and step b., then inspect the wiring for any shorts.

d. If voltage is not present in either case, or the incorrect voltage was measured in step a., then inspect the control module for proper output

voltage at the module and replace if necessary.

e. If both step a. and step b. were OK, then replace the microphones.
