  • It can also be caused by a faulty Hybrid/Electric Vehicle Battery Interface Control Module.
  • These are the only two causes of the P1B50 fault code.

Below are the possible fixes for the automobile fault code p1b50, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1B50, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for 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 P1B50 automobile fault code are the estimated repair time and the hourly rate charged by the auto repair shop. The estimated repair time for this fault code is 1.0 hour. The cost of labor varies between $75 and $150 per hour, depending on the auto repair shop.

These factors are crucial in determining the overall cost of diagnosing and fixing the P1B50 fault code.

The P1B50 code is related to the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel and series. There are three battery sections, each with a different number of cells and cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules. The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2.

The P1B50 code indicates a high voltage in the HybridElectric Vehicle Battery 36 Circuit.
