The estimated repair time for this fault code is 1.0 hour.

The hourly rate charged by most auto repair shops ranges between $75 and $150 per hour.

These factors play a crucial role in determining the overall cost of fixing the U2611 fault code.

The u2611 fault code is related to the loss of communication with the HybridEV Powertrain Control Module 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. 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.

The code indicates that the Auxiliary Transmission Fluid Pump Control Module has lost communication with the HybridEV Powertrain Control Module.

What are the possible causes of the u2611 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u2611 fault code. This code is caused by a faulty auxiliary transmission fluid pump control module, an open or shorted harness, poor electrical connection in the module circuit, or a faulty hybrid/EV powertrain control module. To fix this issue, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can I visually inspect the related wiring harness and connectors to fix the u2611 fault code?
