EWS II Control Module

Replacement EWS II Control Modules must be ordered VIN specific. EWS II modules contain the VIN and coding from the factory to recognize the key codes. Modules from other vehicles will not recognize keys as being valid and not start the engine.

EWS II Control Modules store the Central Coding Key (ZCS) and the VIN. If the EWS II control module is replaced the system must be ZCS coded.

The EWS II module must be synchronized with the DME (aligned). There is no limit to the number of times the ISN may be changed in the EWS II module.
