EWS III (3.2) Control Module

Replacement EWS III (3.2) Control Modules must be ordered VIN specific. The EWS III modules contain the VIN and coding from the factory to recognize the key codes. Use of EWS III modules from other vehicles will result in the keys not being recognized.

The EWS III (3.2) control module stores the ZCS coding and must be coded at time of installation. The module must be aligned with the DME so that it stores the correct ISN. There is no limit to the number of times the ISN may be changed in the EWS III module.
