The factors that influence the cost of fixing the automobile fault code U2615 based on the repair time are: – The estimated repair time is 1.0 hour. – Auto repair shops usually charge between $75 and $150 per hour. – The cost may vary depending on the location and reputation of the repair shop. – The cost may also depend on the severity of the issue and the parts that need to be replaced. – It is important to get a detailed estimate from the repair shop before proceeding with the repairs.

The u2615 fault code is related to the loss of communication with the HybridEV Powertrain Control Module 2 on a high-speed General Motors Local Area Network (GMLAN) bus. The Battery Energy Control Module supervises a periodic serial data message to check the communication status of the HybridEV Powertrain Control Module 2.

If this message is not received within 400 ms, the Battery Energy Control Module increases its fail count.

The DTC will set when a supervised periodic message that includes the transmitter device availability has not been received within 400 ms.
