Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DME Control Modules
Replacement DME Control Modules are "off the shelf" and must be programmed for the specific vehicle. After programming the DISplus software informs the EWS III (3.3) control module that a new DME has been installed. The next time the ignition is switched on, the EWS III (3.3) module will send the entire "Rolling Code Table" to the DME and reset it to "Rolling Code" #1.
The DME will automatically burn the "Rolling Code Table" into its memory. Once the table has been burned into the DME memory it can NOT be changed. For this reason once a DME is "Married" to the vehicle it will not work in any other vehicle.
Under certain condition "Alignment" of the DME and EWS III (3.3) modules may still be necessary. The alignment procedure only resets the code table to code #1 it does not change the "Rolling Code Table".
