[SOLVED] U1534 Code: Fixing Communication Loss Between Body Control Module And Window Motor

The automobile fault code U1534 indicates a problem with the driver window motor or its related components. The most common symptom is the illumination of the engine light or service engine soon warning light. The cause of this fault code could be a faulty driver window motor, an open or shorted harness, a poor electrical connection in the motor circuit, or a faulty body control module (BCM).

The importance of repairing this issue lies in the fact that it can affect the overall performance of the vehicle.

The difficulty level of the repair is moderate, with a repair time of 1.0.

To fix the issue, one 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.

If you see the Engine Light ON, it could be due to the u1534 fault code. Here are some symptoms to look out for:

  • The U1534 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u1534 can be caused by a faulty driver window motor, open or shorted motor harness, poor electrical connection, or a faulty body control module (BCM).

  • The automobile fault code U1534 can be caused by a faulty driver window motor.
  • It can also be caused by an open or shorted driver window motor harness.
  • Another possible cause is a poor electrical connection in the driver window motor circuit.
  • Lastly, a faulty body control module (BCM) can also trigger this fault code.

Below are some possible fixes for the automobile fault code u1534, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1534, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 U1534 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 U1534 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 U1534 code is related to the Local Interconnect Network (LIN) Bus. It occurs when the Body Control Module (BCM) loses communication with the Driver Window Motor on the LIN bus network. The LIN bus consists of a single wire with a transmission rate of 10.417 Kbits.

The serial data is transmitted over a LIN circuit between a master control module and other LIN devices within a particular subsystem.

If serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device. The U1534 code is set when a supervised periodic message to the BCM from the Driver Window Motor has not been received.

What are the possible causes of the u1534 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u1534 fault code. This code can be caused by a faulty driver window motor, an open or shorted driver window motor harness, poor electrical connection in the driver window motor circuit, or a faulty body control module (BCM). To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.
