UDS readDataByIdentifier Rx error

Method: OBD

Issue: An error is returned when attempting to read data from the ECU, indicating a failure in receiving the expected communication packet.

Solution
  • Close and lock the vehicle completely.
  • Wait for at least 5 minutes. This allows the vehicle's ECUs to fully shut down and enter a sleep state.
  • Unlock the vehicle, turn on the ignition, and retry the read operation.
To understand more

This type of error often occurs if the vehicle's communication bus (CAN bus) is busy or if the ECU is in a state where it cannot respond to new diagnostic requests. By shutting down the vehicle for a few minutes, you force a soft reset of the various control units, clearing temporary communication glitches and allowing for a clean connection attempt.
