- Description





KMA is conducting a Service Action in relation to some 2010 MY Forte Sedan and Koup with 2.0L engines and automatic transaxles. Some vehicles may experience a MIL ON with DTC P0304 stored in memory. In most cases the DTC is set only during a cold start and normally the customer does not notice any engine stumble, roughness or performance issues. This PCM upgrade
will eliminate the DTC from setting in the PCM on vehicles produced prior to November 2, 2009.








To correct this condition, the ECM and/or PCM should be reprogrammed using the GDS download as described in this bulletin.
