Module Replacement

REPLACEMENT OF THE EWS CONTROL MODULE

When replacing the EWS control module1 a control module initialized in accordance with the BMW database must be ordered using the same methods (and subject to the same restrictions) that are used when ordering replacement keys. Once installed in the vehicle, the new EWS control module has to be encoded. The following procedure should be observed when encoding:

1. Select the defective, installed EWS control module using the DIS or MoDiC encoding program. It reads out the available data and stores them temporarily in the DIS or MoDiC.

2. Install the new EWS control module.

3. Encode the new EWS control module. During the encoding, data stored temporarily in DIS or MoDiC memory will be transferred to the new control module.

Note:
Should it no longer be possible to diagnose the faulty EWS control module, the chassis number and Central Coding Key must be entered in the new EWS control module manually. After this, the "EWS-DME/DDE synchronization" should be carried out (contained in the MoDiC program "Programming V5.0" and later).

The encoding can be done using DIS/MoDiC version "Encoding ZCS V12.0" or later.

It is not permitted to do a trial replacement by installing an EWS control module which has already been in use in another vehicle. Because the EWS control module has been initialized by the Parts Department, it can only be used in the vehicle for which it was originally ordered. It is not possible to modify initialization through the encoding procedure.

REPLACEMENT OF THE ENGINE CONTROL MODULE

After replacement, a new engine control module must be programmed with the MoDiC. During this process, the individual control module number stored in the engine control module will also be transferred to the EWS control module. If an engine control module that has already been programmed is installed, the "EWS-DME/DDE synchronization" must be carried out.

REPLACEMENT OF THE TRANSCEIVER MODULE

No initialization procedures are required.
