The automobile fault code U0204 has an estimated repair time of 1.0 hour. The cost of fixing this fault code varies depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Therefore, the fixing cost of U0204 can range from $75 to $150.

The repair time is an influential factor in determining the fixing cost of this fault code.

The U0204 code is a Controller Area Network (CAN) fault code. CAN is a vehicle bus standard that connects automotive devices without a host computer. CAN bus uses two dedicated wires for communication: CAN high and CAN low.

The U0204 code sets when a periodic message from the Door Control Module ‘F’ has not been received. This code indicates a lost communication with Door Control Module ‘F’.

The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.

What are the possible causes of the u0204 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u0204 fault code. This code is caused by a faulty Door Control Module ‘F’, an open or shorted harness, or a poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
