[SOLVED] U185C Code: How To Fix Battery Charger Communication Error

The automobile fault code U185C indicates a problem with the HybridEV Powertrain Control Module 2.

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 2, an open or shorted harness, or a poor electrical connection. The importance of repairing this issue lies in the fact that it affects the performance of the vehicle’s powertrain.

The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

It is essential to interpret the fault code correctly to ensure the proper repair of the vehicle.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u185c fault code.

Here are the symptoms to look out for:

  • The U185C fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u185c can be caused by various issues, including a faulty powertrain control module or poor electrical connection.

  • The automobile fault code U185C can be caused by a faulty Hybrid/EV Powertrain Control Module 2.
  • It can also be caused by an open or shorted Hybrid/EV Powertrain Control Module 2 harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Powertrain Control Module 2 circuit can also trigger this fault code.

To fix the automobile fault code u185c, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code u185c, 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 factors that influence the cost of diagnosing and fixing the u185c automobile fault code are: – Estimated repair time of 1.0 hour – Auto repair shops charge between $75 and $150 per hour for labor – The cost of any necessary replacement parts – The complexity of the repair – The experience and expertise of the mechanic performing the repair – The location of the repair shop and local labor rates.

The U185C code is related to the loss of communication with the HybridEV Powertrain Control Module 2.

This diagnostic is used to check the high-speed General Motor 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 1 s, the U185C Diagnostic Trouble Code (DTC) is set.

What are the possible causes of the u185c automobile fault code?

If you’re experiencing the u185c automobile fault code, it’s likely that your engine light is on. This could be due to a faulty Hybrid/EV Powertrain Control Module 2, an open or shorted harness, or a poor electrical connection in the circuit. To fix the 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.

How can I visually inspect the wiring harness and connectors related to the Hybrid/EV Powertrain Control Module 2?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Hybrid/EV Powertrain Control Module 2.
