  • The automobile fault code u0009 can be caused by various factors.
  • These include diagnosing the DTC through the vehicle’s symptoms, checking for additional codes, a faulty control module, an open or shorted control module harness, and poor electrical connection in the control module circuit.
  • It is important to address all of these potential causes in order to effectively resolve the issue and prevent further problems.

Below are some possible fixes for the automobile fault code u0009, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u0009, 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 u0009 automobile fault code are: – Estimated repair time of 1.0 hour – Auto repair shops charge between $75 and $150 per hour – The complexity of the issue – The availability of replacement parts – The expertise of the mechanic – The location of the repair shop – The type of vehicle being repaired – The severity of the issue – The age of the vehicle – The warranty status of the vehicle.

The U0009 fault code is related to the Controller Area Network (CAN) in a vehicle. CAN is a bus standard that connects automotive devices without a host computer. CAN bus uses two wires for communication, CAN high and CAN low.

When the CAN bus is idle, both lines carry 2.5V. When data bits are transmitted, the CAN high line goes to 3.75V, and the CAN low drops to 1.25V, generating a 2.5V differential between the lines. The U0009 code sets when the High-Speed CAN Communication Bus (-) is shorted to Bus (+).

This fault code indicates that a supervised periodic message that includes the transmitter device availability has not been received.
