The automobile fault code U0146 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the U0146 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U0146 fault code indicates a communication problem with the Gateway Module ‘A’. The Gateway Module ‘A’ is responsible for exchanging information and commands among the devices in the Controller Area Network (CAN) bus. The CAN bus uses two dedicated wires for communication, and the Diagnostic Trouble Code (DTC) sets when a periodic message from the Gateway Module ‘A’ has not been received.

This fault code means that the communication between the Gateway Module ‘A’ and other devices in the CAN bus has been lost.
