EWS Control Module

The EWS Control Module is located on the left A Pillar under the dashboard. The EWS Control Module has a "Rolling Code" ISN assigned to it during manufacture. The "Rolling Code" is burned in the permanent memory of the module and can not be overwritten or changed.

The "Rolling Code" is transferred to the EMS2000 on a uni-directional signal line during start-up.

The EWS 3.3 module can accept up to 10 keys.
