CM Update Troubleshooting
Updating Errors
Whenever the MVCI detects an error with the vehicle’s control module/unit update, a caution message appears on
the MVCI. This is often followed by an error code to help you troubleshoot the problem.
1. If you see a caution message on the MVCI, leave the ignition ON. Press ENTER to show the error code.
NOTE:
• If you do nothing, the error screen appears after about 10 seconds.
• Make sure the ignition is ON.
• Do not turn the MVCI off.
• Do not disconnect the MVCI from the vehicle’s DLC.
2. The MVCI usually lists the error code and a brief description of the problem.
• If an error code is listed, refer to Error Code Table for a list of error codes, the error code description, and the
possible solutions. After you note the error code, press ENTER.
• If no error code is listed, but there is a screen message, refer to Error Messages for a list of error messages and
the possible solutions. After you note the error message, press ENTER.
• The MVCI returns to the CM Update Mode software information screen. Press ESC to exit the update.
