This summary uses the existing diagnostic information shown in full below.
The car's computer system is having trouble talking to one of its parts because a connection is broken.
The P3205 code indicates a communication issue within the vehicle's Controller Area Network (CAN), where a CAN chip has been cut off or is not functioning properly.
The P3205 code is triggered when the vehicle's onboard diagnostics detect a loss of communication in the local CAN network, specifically due to a CAN chip being cut off. This can affect the vehicle's ability to communicate between various control modules.
• Check Engine Light illuminated
• Intermittent or complete loss of communication with certain vehicle systems
• Erratic vehicle behavior or performance issues
• Faulty CAN chip
• Damaged wiring or connectors in the CAN network
• Malfunctioning control module
CAN: Controller Area Network, a system that allows communication between different components in a vehicle.
ECU: Engine Control Unit, the main computer in a vehicle that controls engine functions.
• Use an OBD-II scanner to confirm the P3205 code.
• Inspect the wiring and connectors in the CAN network for damage.
• Test the CAN chip and related control modules for functionality.
• Repair or replace damaged wiring or connectors.
• Replace the faulty CAN chip.
• Reprogram or replace the malfunctioning control module.
• OBD-II scanner
• Multimeter
• CAN bus diagnostic tool

Check with your vehicle manufacturer for warranty coverage on electronic components.
The P3205 code has been associated with communication issues in vehicles with advanced electronic systems, particularly hybrid and electric models.
High – This issue can lead to significant vehicle performance problems and should be addressed promptly.
Driving with a communication error can lead to unexpected vehicle behavior, posing safety risks. Address the issue as soon as possible.
• Vehicle at operating temperature
• All electrical systems active
The CAN chip is typically located within the vehicle's main control module or ECU.
Q: What is a CAN chip?
A: A CAN chip is a component that helps different parts of the car's computer system communicate with each other.
Q: Can I drive with a P3205 code?
A: It's not recommended to drive with this code, as it can affect vehicle performance and safety.
