Inspect Software Updates:

• Ensure all control modules have the latest software updates to prevent compatibility issues and internal problems.

Check for System Errors:

• Use diagnostic tools to check for additional system errors that may indicate the source of the internal problem.

Consult Technical Support:

• If the problem persists, consult technical support for further assistance in identifying and resolving the issue.

Note:

Incorrect reprogramming can lead to significant operational limitations. Ensure all reprogramming is performed correctly to maintain proper vehicle function.
