When the configuration is performed, CAN communication between the PCM and control module connected to the CAN line is cut temporarily, and communication error DTCs may be detected. After performing the configuration, verify the DTCs for the control module connected to the CAN line and clear it if any DTC is detected.

5. Verify the DTCs for all of the control modules connected to the CAN line.

If any DTC is stored, clear it.
