The automobile fault code u183c can be caused by various issues, including a faulty powertrain control module or poor electrical connections.

  • The automobile fault code U183C 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.

Below are some possible fixes for the automobile fault code u183c, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u183c, 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 fault code U183C is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is dependent on the repair time.

Most auto repair shops charge between $75 and $150 per hour. Therefore, the cost of fixing the U183C fault code can range from $75 to $150. The repair time is the most influential factor in determining the cost of fixing this fault code.

The U183C code is related to the serial data circuit in a vehicle. It indicates that the Auxiliary Transmission Fluid Pump Control Module has lost communication with HybridEV Powertrain Control Module 2.

This loss of communication can occur due to a power or ground failure. The absence of a state of health message from the non-communicating device triggers the DTC.

It is important to note that the DTC does not indicate a failure of the devices containing the stored code.
