[SOLVED] U2608 Code: Fixing Lost Communication Between A/C & Powertrain Modules

The automobile fault code U2608 indicates a problem with the HybridEV Powertrain Control Module or its related components. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this fault code could be a faulty HybridEV Powertrain Control Module, an open or shorted harness, or a poor electrical connection.

Another possible cause could be a faulty Electric AC Compressor Control Module.

The importance of repairing this issue lies in the fact that it affects the performance of the vehicle’s hybrid or electric powertrain. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour. To interpret the fault code, one needs to use an OBD-II scanner or code reader.

  • The automobile fault code u2608 can be caused by a faulty Hybrid/EV Powertrain Control Module.
  • It can also be caused by an open or shorted Hybrid/EV Powertrain Control Module harness.
  • Another cause can be a poor electrical connection in the Hybrid/EV Powertrain Control Module circuit.
  • Lastly, a faulty Electric A/C Compressor Control Module can also trigger this fault code.

Below are some possible fixes for the automobile fault code u2608, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u2608, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U2608 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of U2608 will range between $75 and $150, depending on the repair time required. It is important to consider the repair time and the hourly rate charged by the auto repair shop when estimating the fixing cost of U2608.

The u2608 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 u2608 code specifically indicates that the Electric AC Compressor Control Module has lost communication with the HybridEV Powertrain Control Module.

What are the possible causes of the u2608 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u2608 automobile fault code. This code is caused by a faulty Hybrid/EV Powertrain Control Module, an open or shorted Hybrid/EV Powertrain Control Module harness, a poor electrical connection in the Hybrid/EV Powertrain Control Module circuit, or a faulty Electric A/C Compressor Control Module. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can the Hybrid/EV Powertrain Control Module harness be checked for faults?

If the engine light is on, it could be due to a faulty Hybrid/EV Powertrain Control Module. To check for faults, inspect the related wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector’s pins. Also, check for poor electrical connections and a faulty Electric A/C Compressor Control Module.

What steps should be taken to fix the u2608 automobile fault code?

If you’re experiencing the u2608 automobile fault code, you may notice that your engine light is on.
