Diagnostic trouble codes (DTC) C1008:15 and/or C1009:15 may be stored in the driver seat module (DSM). DTC U0208 and/or U0244 may also be stored in various other modules. Other DSM functions may be affected such as heated/cooled/memory seats. This may be due to the software in the DSM.<br /><br /> If the DSM does not respond during a network test, press the power seat adjustment switch then re-run the network test to see if DSM communication is restored. Engineering requires feedback for this action. Submit a Global Concern Report (GCR) indicating if DSM communication was restored after actuating the power seat adjustment switch, noting the DTCs present.
