This code means that the car's computer is having trouble talking to one of its parts, like when two people can't understand each other because they're speaking different languages.
The FlexRay communication network in the vehicle is experiencing synchronization issues, meaning the data being sent and received is not properly aligned.
The FlexRay system is a high-speed communication protocol used in modern vehicles for real-time data exchange between electronic control units (ECUs). A synchronization error indicates a failure in the timing or sequence of data packets, which can lead to communication breakdowns between the vehicle's systems.

Communication Error
• Do not ignore the warning light
• Seek professional diagnostic help
• Avoid DIY repairs unless experienced
Check with the vehicle manufacturer for specific warranty coverage related to the FlexRay system.
FlexRay communication issues have been more prevalent in vehicles with advanced electronic systems introduced in the late 2000s.
Moderate – While the vehicle may still be operable, unresolved communication errors can lead to more serious issues.
Driving with unresolved communication errors could lead to safety risks. Always ensure your vehicle is in proper working condition.
• Vehicle parked and engine off
• Access to diagnostic equipment
The FlexRay controller is typically located within the vehicle's main ECU or near the central electronic module.
Q: Can I drive with a P16DA code?
A: It's not recommended to drive for extended periods with this code as it may lead to further issues.
Q: Is a FlexRay controller synchronization error common?
A: It is not very common but can occur in vehicles with complex electronic systems.
