  • The automobile fault code U1510 can be caused by a faulty Heating, Ventilation, and Air Conditioning (HVAC) Control Module.
  • It can also be caused by an open or shorted HVAC Control Module harness.
  • Additionally, a poor electrical connection in the HVAC Control Module circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u1510.

  • To fix the automobile fault code u1510, 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 U1510 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 U1510 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 U1510 code is related to the loss of serial data communication between the HVAC control module and other LIN devices within the subsystem. This code is set by the master control module when it detects a no communication code against the non-communicating LIN device. It is important to note that a loss of serial data communications DTC does not necessarily mean that the master control module has failed.
