SITUATION
The customer states that the vehicle dials BMW Assist(R) on its own, without input from the customer.
CAUSE
1. Emergency call switch fails or sticks.
2. Wiring shorted.
3. TCU hardware failure.
4. The customer presses the MFL Telephone (send/end) button on the steering wheel. The last number dialed is redialed (vehicles prior to 3/2004).
5. One or more of the following faults may be stored in the TCU:
0C74: Emergency call button jammed (I/K-bus vehicles only)
0X6D: Emergency call button, open circuit (I/K-bus vehicles only)
0X80: Service button, open circuit (I/K-bus vehicles only)
0X81: Service call button jammed (I/K-bus vehicles only)
A370: Emergency call button - Shorted to B+ (MOST-bus vehicles only)
A36D: Emergency call button - Open circuit (MOST-bus vehicles only)
A374: Emergency call button jammed (MOST-bus vehicles only)
PROCEDURE FOR E46 (NON CONVERTIBLE), E53, E65, E66, E83, E85 & E86 VEHICLES
1. Duplicate customer complaint. Can the complaint be duplicated?
- Yes, disconnect the SOS switch. If the system stops calling BMW Assist, proceed to step 11.
- No, proceed to step 2.
2. Perform a short test using the BMW Diagnostic Tools.
3. Does the TCU have one of the below listed faults stored in fault memory the TCU?
0C74: Emergency call button jammed
0X6D: Emergency call button, open circuit
0X80: Service button, open circuit
0X81: Service call button jammed
A370: Emergency call button - Shorted to B+ (MOST-bus vehicles only)
A36D: Emergency call button - Open circuit (MOST-bus vehicles only)
A374: Emergency call button jammed (MOST-bus vehicles only)
- If Yes, complete the test module for that fault. If the test module states to replace the TCU, refer to the TCU replacement Procedure in this bulletin.
- No, Proceed to step 4.
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 more information.
- If the customer has an active BMW Assist services account, test the BMW Assist services following the information outlined in 'Testing of BMW Assist Services' section of this bulletin.
5. [NEW] On E46, E53, E83, E85 and E86 vehicles, check the operation of the emergency call switches (roadside and emergency). The status can be monitored via DISPlus/GT1 Control Module function for TCU (Telematics Control Unit). The status should change when the buttons are press.
6. Disconnect the 6-pin connector SOS switch and measure the voltage at the following pins and ground.
- Pin 4 (SOS)
- On vehicles equipped with both a SOS and a Roadside (wrench) assistance buttons, check pin 1 (Roadside)
- There should be approximately 12 volts. If the readings are not the same for both buttons on the switch (for example roadside= 12.00 volts and emergency=9.5 volts) proceed to step 7.
7. Disconnect the 54-pin TCU ELO connector and connect adapter cable (90 88 6 630 400) only to the wiring harness and to the 88-pin breakout box (88 88 6 614 410). Do not connect the TCU to the breakout box.
- Check for continuity between pin [NEW] 4 of the SOS switch connector and pin 31 of the 54-pin TCU connector.
- On vehicles equipped with both a SOS and a Roadside assistance (wrench) buttons, check for continuity between pin 1 of the SOS switch connector and pin 26 of the 54-pin TCU connector.
- If you have continuity, proceed to the step 8.
- If you do NOT have continuity, repair wiring as necessary.
8. Check all the wiring between the switch and the TCU for opens and shorts. If the wiring check is good, then proceed to step 9.
9. Reconnect the switch that was previously disconnected and check the resistance of each circuit as outlined in steps 10 and 11.
10. On vehicles equipped with both a SOS and a Roadside assistance (wrench) buttons, check the resistance from pin 26 of the 54-pin TCU connector to ground.
- Switch not pressed: circuit open.
- Switch pressed: circuit shows 100-200 ohms.
11. Check the resistance of pin 31 of the 54-pin TCU connector to ground.
- Switch not pressed: circuit open.
- Switch pressed: circuit shows 100-200 ohms.
If the wiring and switch are good, the TCU should be replaced. Proceed to the 'TCU REPLACEMENT PROCEDURE'. If the switch resistance is not correct, replace the switch.

TCU REPLACEMENT PROCEDURE
1. It is NOT necessary to obtain a Part Replacement Authorization (TeileClearing) for this specific issue. Refer to the Warranty section of this bulletin for more details. Additional information can be found in SI B84 23 05 (Enhanced Support for BMW Assist Telematics Control Unit (TCU) with Bluetoothreg; & CPT9000 Phone Systems).
2. Refer to TIS (RA 84 11...) for the TCU replacement procedure.
3. Before installing the new TCU, remove one copy of the Electronic Serial Number (ESN) label and place it on the repair order for reference during warranty claim entry. You will be asked for the new TCU "ESN" when submitting a claim via DCSnet. Refer to SI B01 10 05 for more details.
4. The second ESN label of the TCU should be affixed over the existing label in the Owner's Manual insert (P/N 01 49 0 157 963).
5. Complete the TCU installation
6. Using Progman V27.01.00 or higher, program the complete vehicle. Refer to SI B09 05 01 "Coding, Individualization and Programming", Procedure A.
7. On E60, E61, E63, E64, E65 (from 3/05), E66 (from 3/05) E70, E90, E91, E92 and E93 vehicles:
Initialize BMW Assist following the procedure as outlined in the 'INITIALIZATION OF BMW ASSIST SERVICES" section of this bulletin.
8. Test BMW Assist by following the procedure outline in the "TEST OF BMW ASSIST SERVICES' section of this bulletin.
INITIALIZATION OF BMW ASSIST SERVICES ON E60, E61, E63, E64, E65 (FROM 3/05), E66 (FROM 3/05), E70, AND E90, E91, E92 AND E93 VEHICLES
1. The BMW Assist services initialization procedure must be completed per SI B84 15 03 for all vehicles.
