How to Fix U1461

  1. Begin by conducting a thorough inspection of the wiring and connections in the CAN bus network to check for any visible damage or loose connections.
  2. Use a diagnostic scanner to retrieve and clear the U1461 code, then monitor the data communication between the ESM and DPT modules to identify any inconsistencies.
  3. Test the sensors providing input to the ESM and DPT modules to ensure they are functioning correctly and providing accurate data.
  4. If no issues are found with the wiring, connections, or sensors, consider reprogramming or replacing the ESM or DPT module as needed.
  5. After the repair is completed, perform a test drive to verify that the symptoms associated with the U1461 code have been resolved.

Cost to Fix U1461

The typical repair costs for addressing the U1461 code can vary depending on the specific cause of the issue and the necessary repairs. In general, resolving communication issues between modules like the ESM and DPT can range from $200 to $800, including parts and labor. However, it is essential to note that the specific diagnosis time and labor rates at auto repair shops can vary significantly based on factors such as location, vehicle make and model, and engine type. It's recommended to inquire about local rates to obtain a more accurate estimate for this repair.
