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.
Manually Entering the Variant Code
This method is required if the control module is defective and can not communicate with the DIS/MoDiC over the diagnostic link. The variant code is determined reading the label on the defective control module and double checking it with the variant codes in the appropriate articles or in the DME VARIANT CODES .
Follow steps 1 through 6 and continue below.
- 7. Select "2 Enter Code Manually" and press the enter button.
- 8. Turn the ignition off and remove the old control module. Install the new control module and turn the ignition back on.
- 9. Determine the variant code.
- 10. Carefully enter the code using the onscreen keypad.
When the code is correctly displayed on screen, press the "Yes" button to confirm the entry.
- 11. The DIS/MoDiC will display the remaining number of times the control module can be encoded. Press the "Yes" button to transfer the code.
- 12. Coding is complete. The DIS/MoDiC displays the installed variant code. If the code is displayed as FF01 (basic control module code) the coding procedure must be repeated.
- 13. Complete a new DME variant code label and place it on the control module.
The coding procedure is complete!
