  • Additionally, the vehicle may have issues with the speedometer or other gauges, and the vehicle may stall or have difficulty starting.

The automobile fault code u1064 can be caused by a faulty BCM, open or shorted BCM harness, or poor electrical connection.

  • The automobile fault code U1064 can be caused by a faulty Body Control Module (BCM).
  • It can also be caused by an open or shorted Body Control Module (BCM) harness.
  • Additionally, a poor electrical connection in the Body Control Module (BCM) circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code u1064, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1064, 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 automobile fault code U1064 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the U1064 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U1064 code is related to the class 2 serial data circuit in automobiles. Modules in the circuit monitor for serial data communications during normal vehicle operation.

When a module doesn’t receive a message for a critical operating parameter, it records the identification number of the module which sent the message. If no message is detected from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1064 is set.

This code indicates that there is a lost communication with the Body Control Module.
