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.
Determination Process for DME EPROM
In the event a DME EPROM, a control module or the program of a control module needs to be updated or replaced the program contained within CIP will provide the information necessary to perform the specific task. A program within CIP is used to determine the correct replacement part numbers (EPROM, Control Module or software update) to be installed.
For earlier production vehicles there are two ways to perform this process:
- "automatic" determination
or
- "manual" determination.
The automatic determination is the preferred method as it is faster and mistakes made during data entry into the tester are avoided. For newer production vehicles that utilize EEPROMs/Flash programming the determination process is done automatically as part of determining a measures plan (refer to CIP section or more information).
