This code means that there is a problem inside the car's computer that helps control stability and braking. It's like when a computer game freezes because there's a bug in the software.
The code indicates an error within the Dynamic Stability Control (DSC) module related to the FlexRay communication system, which is crucial for data exchange in modern vehicles.
The C1085 code is triggered when the DSC control module detects an internal fault in the FlexRay controller. FlexRay is a high-speed communication protocol used in automotive networks to ensure reliable data transmission between control modules. An error in this system can affect the vehicle's stability control functions.
• Stability control warning light on
• Loss of stability control functionality
• Intermittent braking issues
• Faulty DSC control module
• Wiring issues in the FlexRay network
• Software glitch in the DSC module

Repairs may be covered under the vehicle's powertrain or electronic component warranty, depending on the age and mileage of the vehicle.
This code has been more prevalent in vehicles with advanced electronic stability systems, particularly in models with high-speed communication networks.
High – This issue can affect vehicle safety systems and should be addressed promptly.
Operating a vehicle with impaired stability control can increase the risk of accidents. Always ensure safety systems are functioning correctly.
• Vehicle must be on a flat surface.
• Ensure the battery is fully charged.
The DSC control module is typically located under the dashboard or in the engine bay, depending on the vehicle model.
Q: Can I drive my car with this code?
A: It's not recommended, as the stability control system may not function properly, increasing the risk of accidents.
Q: Will resetting the code fix the problem?
A: Resetting the code may temporarily clear the warning light, but it won't fix the underlying issue.
