This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble keeping track of the date and time, like when a clock is not set correctly.
This code indicates that there is a problem with the synchronization of the date and time settings in the vehicle's control module.
The control module is responsible for managing various functions in the vehicle, including keeping track of date and time. A synchronization error means that the module is unable to maintain or update the correct date and time, which can affect other time-dependent functions.
• Incorrect date and time display
• Malfunctioning time-dependent features
• Possible warning light on dashboard
• Faulty control module
• Software glitch or bug
• Battery voltage issues
Control Module: A computer in the vehicle that manages various functions.
Synchronization: The process of ensuring two systems work together at the same time.
• Check the vehicle's battery and charging system.
• Inspect the control module for any software updates.
• Use a diagnostic scanner to check for additional error codes.
• Update the control module software.
• Replace the control module if faulty.
• Ensure battery and electrical connections are secure.

This code has been observed in hybrid and electric vehicles where control module synchronization is critical.
Moderate – It should be addressed to ensure proper vehicle functionality.
Driving with incorrect date/time settings may affect certain time-dependent features, but it is generally safe.
• Vehicle in park with engine off.
• Access to diagnostic tools.
The control module is usually located under the dashboard or near the engine bay.
Q: Can I drive with this code?
A: Yes, but it's best to have it checked to ensure all features work properly.
Q: Will this code affect my vehicle's performance?
A: It may affect time-dependent features, but not the overall performance.
