When the transfer case control module has to move the transfer case actuator motor the higher current passing through the module causes an \"electronic buzz or whine\" within some of the capacitors in the module that can be heard by some of our customers. This can only be heard with all accessories and HVAC off and only when actuator movement is required. This does not indicate a concern with the module and should not be replaced to address this concern.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10114369-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10114369-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10114369","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"CADILLAC","model":"ESCALADE","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_cadillac_escalade"]},{"make":"CADILLAC","model":"ESCALADE ESV","year_from":2015,"year_to":2015,"match":"base","vehicle_ids":["2015_cadillac_escalade"]},{"make":"CHEVROLET","model":"SILVERADO 1500","year_from":2014,"year_to":2014,"match":"base","vehicle_ids":["2014_chevrolet_silverado"]},{"make":"CHEVROLET","model":"SILVERADO 2500","year_from":2014,"year_to":2015,"match":"base","vehicle_ids":["2014_chevrolet_silverado","2015_chevrolet_silverado"]},{"make":"CHEVROLET","model":"SUBURBAN","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_chevrolet_suburban"]},{"make":"CHEVROLET","model":"TAHOE","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_chevrolet_tahoe"]},{"make":"GMC","model":"SIERRA 1500","year_from":2014,"year_to":2014,"match":"base","vehicle_ids":["2014_gmc_sierra"]},{"make":"GMC","model":"SIERRA 2500","year_from":2014,"year_to":2015,"match":"base","vehicle_ids":["2014_gmc_sierra","2015_gmc_sierra"]},{"make":"GMC","model":"SIERRA DENALI","year_from":2015,"year_to":2015,"match":"base","vehicle_ids":["2015_gmc_sierra"]},{"make":"GMC","model":"YUKON","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_gmc_yukon"]},{"make":"GMC","model":"YUKON XL","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_gmc_yukon-xl"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
