PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
SUBJECT
Service Action - Reprogramming DME on E46 M56 SULEV Vehicles
MODEL
E46 M56 (SULEV) vehicles produced 04/09/2002 - 10/31/2002
SITUATION
Updated DME control module programming is available. The programming as originally installed could, under certain rare operating and ambient conditions, cause an evaporation system DMTL pump fault code to be stored, even though no fault exists. The "Check Engine" light would also be illuminated.
AFFECTED VEHICLES
This Service Action involves E46 vehicles with M56 engines, which were produced from April 9th, 2002 up to October 31st, 2002.
In order to determine if a specific vehicle is affected by this Service Action, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communication System). Based on the response of the system, either proceed with the corrective action or take no further action.
The Chassis Number Ranges listed are only for informational purposes and are not to be considered as the only deciding factor.
CORRECTION
Reprogram DME control module using DISPlus/GT1 loaded with CD 32.0 or higher.
PROCEDURE
To reprogram DMB control module:
1. Connect vehicle to a BMW approved battery charger.
2. Connect DISplus/GT1 loaded with CD32 or higher.
3. Select: BMW Coding/Programming
4. Select: 5 Programming, then right arrow
5. Select: 3 DME Programming, then right arrow
6. Display appears First determine and then program basic control unit, then right arrow
7. Select / Determine basic control unit, then right arrow. Automatic determination is going to be performed.
8. DME, is the faulty control unit still installed in the car?, select YES
9. Start automatic determination?, select YES
10. Display appears: Compare chassis number displayed with number in the car. Chassis number.... Do numbers correspond? Select YES
11. Part number basic control unit...../..... are displayed, then scroll down
12. Display appears: Followed part numbers (basic control unit) can likewise be used. A new program version is also programmed for these part numbers. Duration depends on control unit between 4 - 16 minutes, then scroll down
13. At this point vehicle data is stored in the tester for the automatic identification. Disregard screen prompt which refers to obtaining and installing a new basic control unit, and scroll to the left
14. Select: 2 Exchange control unit, then right arrow
15. Select: 2 Program basic control module, then right arrow
16. Follow instruction: Chassis number, enter the last 7 characters of VIN. Is the number correct?
Select YES
17. Disregard the next instruction: Install new basic control module, just go forward by pressing right arrow
18. Display will appear: There is new program version and new data version for this control unit.
Depending on the control unit, programming may last between 4-16 minutes. First programming and then data are programmed. After programming, with diagnosis program, the fault memories have to be cleared. EWS alignment is automatically carried-out with reprogramming. The adaptation values must be cleared after programming, then right arrow.
IMPORTANT:
On a few early vehicles equipped with Kombi instrument cluster version SW 31, at this point of the procedure the instrument cluster has to be disconnected. Otherwise, message "Communication disrupted, check battery voltage...." is displayed when programming is continued. After cluster disconnection, follow the next programming steps. Instrument cluster has to be connected again after programming completion, but prior to DMB/EWS alignment.
Situation is caused by communication conflict between Kombi SW 31 and DME programming protocol KWP0000*. Vehicles equipped with the newer version of Kombi SW32 would not exhibit this type of behavior.
19. The next screen displays: The control module can be programmed X times, then right arrow
20. Follow the command: Please enter reading mileage..... Entry correct?. Select: YES
21. Start automatic programming? Select: YES
22. When programming starts, the following message is displayed: Program programming active.
Voltage terminal 30.....
23. Afier programming part is finished, the following message is displayed: Data programming active.
Voltage terminal 30.....
24. After successful programming, message is displayed: Programming completed.
25. Next, follow screen instructions for EWS alignment, clearing of adaptation values, and for printing new DME label.
LABEL INSTRUCTIONS
This Service Action has been assigned code number 346 After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-205) and:
a. emboss your BMW dealer warranty number in the middle of the label (1);
b. punch out code number 346 printed on the label and,
c. affix the label to the B pillar as shown.
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one because a number from an underlying label could appear in the punched-out hole of the new label.
WARRANTY INFORMATION
Reimbursement for this service Action will be via Campaign Entry.
