This code means that there's a problem with the car's communication system, like when your phone can't connect to Wi-Fi.
The FlexRay transceiver is part of the car's communication network that allows different parts of the car to talk to each other. This code indicates an electrical issue in that network.
The C1106 code is triggered when there is an electrical fault in the FlexRay transceiver circuit. FlexRay is a high-speed communication protocol used in advanced automotive systems to ensure reliable data exchange between electronic control units (ECUs). An electrical issue could mean a short circuit, open circuit, or other wiring problems affecting the transceiver's ability to function correctly.

Communication Network Issue
• Have the vehicle inspected by a professional technician.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on communication system components.
The C1106 code has become more prevalent with the increased use of FlexRay networks in modern vehicles for advanced communication needs.
Moderate – It is important to address this issue to prevent communication failures between vehicle systems.
Driving with unresolved communication issues may lead to unexpected vehicle behavior, posing safety risks.
• Vehicle in ignition ON position.
• Ensure all systems are powered.
The FlexRay transceiver is typically located within the vehicle's ECU or near the communication network hub.
Q: Can I drive my car with a C1106 code?
A: It's not recommended to drive with this code active, as it may cause unpredictable vehicle behavior.
Q: How do I know if my FlexRay transceiver is faulty?
A: A professional technician can diagnose this by testing the transceiver and inspecting the wiring.
