Technical Background
Continual improvements to MMI software provides solutions to issues experienced in the field.
Production Solution
Improved software.
Service
A software update can be performed.
Note:
Please review this entire bulletin before proceeding and follow all steps exactly to avoid damage to the MMI components. If at any time it is unclear how to proceed, please contact TAC.
1. As part of the update, wireless settings and paired devices will be deleted. All devices will need to be re-paired after the update, and all wireless settings restored to the customers settings. To access the Wireless network settings on the MMI (Figure 1), press TEL >> Settings >> Wireless network connection >> Wireless network settings. Record all settings so they can be re-entered at the end of the update.
2. Update the MMI software following the instructions in TSB 2028141, Generic instructions for updating MMI 3G / MMI 3G+ software and navigation data; using the appropriate update disc for this vehicle:
Note:
The MMI system may remain blank for extended periods of time during the update. If the screen remains blank for over 20 minutes, please contact TAC.
Note:
Some earlier model year 2012 vehicles, or vehicles equipped with Bose(R) sound systems may experience certain modules that will not update properly during Step 16 of TSB 2028141. If this should occur, either choose Cancel (Figure 2), or Skip device (Figure 3), depending on the type of error. Do not choose Cancel update, as this may cause the software update to fail entirely. After the update is finished and the summary page is shown, select Retry at the bottom of the list if it is available to attempt to update the modules again. If Retry is greyed out, then the software update was successful, so select "Continue" to proceed. In some cases Retry may have to be repeated two or three times to get all modules to update successfully.
3. Verify that the software update has been completed successfully by accessing the logging page (Figure 4). To access this screen, proceed to step 8 in TSB 2028141 and press the lower left softkey. A successful update will show the date the update was performed and the software that was installed (HN+R_US_AU_K0566_X), with OK listed on the right. The X may be one of several different numbers. If K0566_X does not have any rows with OK, the update must be retried until it is successful.
Tip: If the update must be performed two or more times due to modules not updating correctly, a screenshot of the software update log is required (Figure 5). This should be kept on-hand for warranty auditing purposes. To take a screenshot, insert an SD Card into slot 1 and press and hold the left and right arrow keys at the same time. All 4 softkeys will flash when the screenshot is taken. A screenshot should be taken of each page in the logging display.
4. Perform SVM code listed on the MMI update disc to establish a reference for this vehicle, and add the test plan to clear DTCs created from the update. If any errors are encountered while performing the SVM code, please call TAC and attach the Diagnostic log showing the error.
5. Using the recorded Wireless network settings from Step 1, reenter the values to restore the settings to the customers selections. Inform the customer that Wi-Fi and Bluetooth devices will need to be reconnected to the vehicle.
