If the vehicle is left in this state for an extended amount of time, the battery may become discharged.<\/p>\n<p style=\"font-weight: 400;\">These conditions may be caused by a failed OTA update for the Serial Data Gateway Module (SDGM)<\/p>\n<p style=\"font-weight: 400;\">To address this concern, check to see if the vehicle has recently received an OTA update. On the infotainment screen, select Settings &gt; System &gt; Updates. (Fig. 6) If the OTA update failed, it may not show under the updates history on the infotainment screen.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"font-weight: 400; text-align: center;\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-17315\" src=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2023\/03\/F06-OTA-1.png\" alt=\"\" width=\"740\" height=\"480\" srcset=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2023\/03\/F06-OTA-1.png 740w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2023\/03\/F06-OTA-1-300x195.png 300w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2023\/03\/F06-OTA-1-85x55.png 85w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2023\/03\/F06-OTA-1-200x130.png 200w\" sizes=\"(max-width: 740px) 100vw, 740px\" \/><strong>Fig. 6<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"font-weight: 400;\">Also check the condition of the battery following the procedures in the appropriate Service Information.
