  • The automobile fault code u0446 can be caused by a faulty Body Control Module (BCM) ‘E’.
  • It can also be caused by an open or shorted Body Control Module ‘E’ harness.
  • Additionally, a poor electrical connection in the Body Control Module ‘E’ circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u0446, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u0446, 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 u0446 automobile fault code are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour. The cost of auto repair shops varies between $75 and $150 per hour.

These factors are crucial in determining the overall cost of fixing the u0446 fault code.

The u0446 fault code is related to the Controller Area Network (CAN) in a vehicle.

CAN is a standard that connects automotive devices without a host computer. The devices exchange operating information and commands through programmed messages on serial data circuits. The u0446 code is set when a receiving device detects a discrepancy in the information it receives from the Body Control Module (BCM) ‘E’.

This causes the integrity of the information to be questioned, resulting in an invalid data Diagnostic Trouble Code (DTC).

It indicates that there is a problem with the communication network between the BCM and the receiving device.

What are the possible causes of the u0446 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u0446 fault code. This code is often caused by a faulty Body Control Module (BCM) ‘E’, an open or shorted Body Control Module ‘E’ harness, or a poor electrical connection in the Body Control Module ‘E’ circuit. To fix this issue, you 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.

How can I visually inspect the related wiring harness and connectors to fix the u0446 fault code?

If you’re experiencing the u0446 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few things you can do to fix it.
