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.
Programming Update
Updates are refered to as "Customer Service Measures" in the programming software. The existing program in the control module is amended with an updated program. This new data changes various operations of the existing control programming. Program updates write the new data in a reserved section of the EPROM. The location of the old data is overwritten with instructions for the DME to search the reserved section in the EPROM when the function is required.
THE UPDATE CANCELS THE OLD FUNCTIONS CHARACTERISTICS AND ADDS THE UPDATED FUNCTION TO THE EPROM
Because of limited space on the EPROM, program updating can only be done one time.
The DIS/MoDiC will display the message "Measure not applicable to the control module version" if update has already been done or the DME is factory updated.
