ECM UPDATE FOR OBD LOGIC IMPROVEMENT (SC203)
This bulletin provides the procedure to improve the logic of the Engine Control Module (ECM) on some 20172018MY Forte (YDm) vehicles equipped with the NU 2.0L MPI engine, produced from May 27, 2016 through
June 27, 2018. Affected vehicles may have had a software update that turned off certain fuel system
monitoring functions. While this issue has no effect on the drivability of the vehicle, nor does it release any
air pollutants, the vehicle may fail a SMOG check and/or may not illuminate the Malfunction Indicator Light
(MIL) for certain fuel system failures. In order to improve On-Board Diagnostics (OBD) logic, apply the
improved software logic to the Engine system using the KDS ECU Upgrade function as described in this
bulletin. For confirmation that the latest reflash has been applied to a vehicle you are working on, verify the
ROM ID using the table on page 3 of this bulletin. Before conducting the procedure, verify the vehicle is
included in the list of affected VINs.
