PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.

SUBJECT
Reprogramming the TCM/EGS

MODEL
E36 Z3 roadster/coupe with M54 produced up to 11/00
E46 3 Series with M54 produced up to 11/00

SITUATION

Due to a transmission control module (TCM / EGS) software error, a communication conflict may exist between the TCM and an "aftermarket" scan tool. This may prevent the TCM from displaying the control module's "calibration identification" on the "off-board" scan tool display.

AFFECTED VEHICLES

This service action involves E36 Z3 and E46 vehicles with the M54B25 and M54B30 engines which were produced up to 11/2000.

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 shown are only for informational purposes and are not to be considered as the only deciding factor.

CAUSE

TCM/EGS program error

CORRECTION PROCEDURE

Reprogram the TCM/EGS with CD25 or higher.

1. Using CD25 or higher, reprogram the TCM.

2. Using the DIS/MODiC, select:

-- 4 Programming: "Programming Drive P25.0"

-- 1 "Exchange control unit"

-- 1 "Determine basic control unit"

-- "Is faulty control unit still installed in car" select "YES"

-- "Turn on ignition - start automatic determination" select "YES"

-- "Automatic determination active - please wait"

-- Follow the directions to complete the programming and clearing of the adaptations.





3. For reference only, the numbers shown will be installed after programming with CD25.

LABEL INSTRUCTIONS

This service action has been assigned code number 296. After the vehicle has been checked, and corrected if necessary, obtain a label (SD92-155) and:

a. emboss your BMW dealer warranty number in the middle of the label (1);

b. punch out code number 296 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 provided through campaign entry without regard to vehicle age or mileage.
