SITUATION
When placing a phone call, the customer has one of the following complaints:
^ Complaint # 1: The person on the landline side of the call cannot hear the person in the vehicle but the person in the vehicle can hear the caller.
^ Complaint # 2: The person in the vehicle cannot hear the landline side of conversation, but the person on the landline side can hear the caller in vehicle.
COMPATIBLE HANDSET INFORMATION
Before the complaint can be addressed, the particular handset must be verified for compatibility. On vehicles equipped with BMW Assisttrade; with Bluetoothreg; wireless technology, confirm whether or not the phone is compatible. Visit www.bmwusa.com/bluetooth for a list of handsets that have passed BMW testing for compatibility. Note the following disclaimer on this web site:
^ "This list is provided for reference only. The mobile phones listed here have passed compatibility tests as of the date of testing and meet or exceed minimum standards established by BMW. The list is not a warranty for phone performance or functionality. BMW makes no guarantees or warrantees as to the performance of each phone while connected to your BMW via Bluetooth Wireless Technology. Furthermore, software releases by BMW, the phone supplier or the wireless carrier dated after testing might alter compatibly results. While many phones are offered with Bluetooth Wireless Technology, not all phones support the necessary profiles to work with your BMW. BMW does not guarantee availability or functionality with all wireless carriers. Functions such as synchronizing the address book and transferring a call into or out of the vehicle may function differently from phone to phone".
PROCEDURE FOR COMPLAINT # 1
When the person on the landline side of the call cannot hear the caller in vehicle, check the following:
1. Verify the customer's complaint.
2. Check the production date of the vehicle.
^ E60, E63 and E64 - The TCU hardware in vehicles built prior to 3/04 production does NOT support Bluetooth technology and will exhibit this complaint.
^ E46, E83 - The TCU hardware in vehicles built prior to 9/04 production (325i/iA from 10/04) does NOT support Bluetooth technology and will exhibit the same complaint.
^ E53, E85 - The TCU hardware in vehicles built prior to 10/04 production does NOT support Bluetooth technology and will exhibit the same complaint.
If a customer would like to upgrade the vehicle to support Bluetooth wireless technology at their own expense, please refer to SI B84 14 05.
3. Perform a short test using BMW Diagnostic tools. Work through any corresponding test modules.
4. Check the BMW Assist account status on DCSnet. The BMW Assist services expiration date and the TCU activation status can be checked on DCSnet under Service/Vehicle History Inquiry. Refer to SI B02 01 06 (Updated DCSnet Vehicle History Inquiry information on BMW Assist) for additional information.
5. Does the customer have an active BMW Assist contract?
^ If no, proceed to step 7.
^ If yes, check the microphone circuit by placing a BMW Assist call. Follow the procedure outlined in the "TEST OF BMW ASSIST SERVICES" section of this bulletin. Then proceed with step 6.
If the connection is established but voice communication is not established, call BMW Assist Customer Care immediately at (888) 333-6118, option #4 to cancel the dispatch. Failing to call will result in local emergency services being dispatched to your location.
6. Does the audio work both ways when making an assist call?
^ If yes, proceed to step 11 because if the audio is OK during an Assist call. This means you have verified the integrity of the microphone circuit.
^ If no, proceed to step 7.
7. Check microphone circuit. Perform test module B8400_00122.
^ If the test module is inconclusive, proceed to step 8.
^ If the test module is conclusive, follow the BMW diagnostic tool's recommended repair.
8. Check for voltage between pin 1 and 2 at the microphone. Was it between 9 and 9.5 volts?
^ If yes, proceed to step 9.
^ If no, disconnect the 54 pin connector (X14133) at the TCU. Check the wiring for shorts or an open circuits. If a wiring problem is found, repair as necessary and retest.
^ Pin 1 at the TCU goes to pin 1 at the microphone.
^ Pin 19 at the TCU goes to pin 2 at the microphone.
9. Install a breakout box between the TCU and the 54 pin connector (X14133).
10. Using oscilloscope function of BMW Diagnostic tools, check between pin 1 (MIC+) and pin 19 (MIC-) while someone is speaking into the microphone.
^ If there is corresponding oscillation to someone speaking into the microphone, the microphone circuit is OK. Proceed to step 11.
^ If there is no oscillation and the wiring you testing in step 8 passed, replace the microphone. Retest the system.
11. Delete all paired devices from the TCU following the 'PROCEDURE - DELETING PAIRED DEVICES' section of this bulletin.
12. Pair a known good (reference) compatible handset with the vehicle following the procedure outlined in SI B84 13 04.
13. Allow the phone book to complete downloading.
14. Place a phone call. Does the landline side audio work correctly?
^ If yes, the problem is a handset issue. No further diagnosis is necessary. Have the client advisor inform the customer the problem is a handset issue. Refer the customer to www.bmwusa.com/bluetooth to obtain details on the latest list of compatible handsets.
^ If no, proceed to step 15.
15. If the reference handset has the same problem and the microphone circuit is good, the TCU is defective, refer to the "TCU REPLACEMENT PROCEDURE" section of this bulletin.
PROCEDURE FOR COMPLAINT # 2

If the connection is established but voice communication is not established, call BMW Assist Customer Care immediately, at (888) 333-6118, option #4 to cancel the dispatch. Failing to call will result in local emergency services being dispatched to your location.
10. Does the audio work both ways when making an assist call?
^ If no, proceed to step 11.
^ If yes, the audio circuit is OK. This also means the wiring from the TCU to the radio / head unit is OK and the output stage of the radio is OK. The TCU is defective; refer to the "TCU REPLACEMENT PROCEDURE" section of this bulletin.
11. Was an iPod adaptor or an auxiliary input retrofitted into the vehicle?
^ If yes, check the wiring at the back of the radio. The wires were to be transferred from the original connector to the connector that comes with the aux/iPod wiring harness.
^ Refer to the specific installation instructions for the accessory that was installed in the vehicle.
^ Note: The installation instructions can be obtained from Aftersales Assistance Portal (ASAP).
Steps 12 to 16 are for I/K-bus vehicles (E.g. E46, E53, E83, E85, E86) only.
12. Check the following at the radio:
^ Pin 10 is the 'Telephone mute' signal--- Does the signal change when a call is placed? Note: this is a high / low signal.
^ If yes, the circuit is OK.
^ If no, check the mute signal as outlined in step 14.
^ Pin 11 is the 'Telephone on' signal --- Does the signal change when a call is placed? Note: this is a high / low signal.
^ If yes, the circuit is OK.
^ If no, check the Telephone on signal as outlined in step 14.
^ Pin 6 and 12 is the speaker circuit coming from the TCU. Scope the circuit and place a phone call. Is an oscillation pattern seen that correlates to the person on the landside of the call speaking?
^ A, If yes, the circuit is OK.
^ If no, check the speaker circuit as outlined in step 14.
13. If the 'Telephone mute' signal, 'Telephone on' signal and the speaker circuit are all good, replace the radio.
14. In accordance with your results in step 12 check the following circuits at the 54 pin connector of the TCU with the wires removed from the harness connector:
^ Pin 51 is the 'Telephone mute' signal. Does the TCU output signal change when a call is placed? Note: this is a high / low signal.
^ If yes, the TCU output OK, proceed to step 15.
^ If no, proceed to step 16.
^ Pin 33 is the 'Telephone on' signal. Does the TCU output signal change when a call is placed? Note: this is a high / low signal.
^ If yes, the TCU output OK, proceed to step 15.
^ If no, proceed to step 16.
^ Pin 37 and 38 are the speaker circuit. Is an oscillation pattern seen that correlates to the person on the landside of the call speaking?
^ A, If yes, the TCU output OK, proceed to step 15.
^ If no, proceed to step 16.
15. If all the signals check OK, check and repair the wiring between the TCU and the radio.
16. If the signal is not OK, the TCU is defective. Refer to the "TCU REPLACEMENT PROCEDURE" section of this bulletin.
17. On MOST-bus vehicles (E60, E63, E65, E70, E90, etc.), perform a head unit audio tone test using BMW Diagnostic tools. Did the head unit pass the audio tone test?
^ If no, continue diagnosis of the head unit.
^ If yes, the TCU is defective; refer to the "TCU REPLACEMENT PROCEDURE" section of this bulletin.
