The car's computer system that helps keep it stable has a communication problem. It's like when your walkie-talkie stops working, and you can't talk to your friend.
The Vehicle Dynamics Control Module is experiencing a communication error with the FlexRay network, which is crucial for vehicle stability and control.
The C1116 code indicates that there is a problem with the FlexRay transceiver in the Vehicle Dynamics Control Module. FlexRay is a high-speed communication system used in modern vehicles to ensure real-time data exchange for vehicle stability and control functions. A shutdown path error means the transceiver is unable to maintain proper communication, potentially affecting vehicle dynamics systems.
