There may have been a charging system message, battery warning lamp or service hybrid system message displayed and may have Diagnostic Trouble Code P0C32 and or P0A7E. If the voltage level drops to a predetermined level approximately 9 direct current volts use Global Diagnostic System 2 to command the battery pack cooling fan motor on to make sure it operates. If the fan does not operate it will need to be replaced. Technician may need to run the vehicle through several drive cycles to ensure that there is not another root cause for the low voltage condition. Technician will need to reprogram the generator control module.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10113966-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10113966-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10113966","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"battery","name":"12-volt battery","parent":"electrical"},{"id":"software","name":"Software","parent":"electrical"}],"codes":["P0A7E","P0C32"],"topics":[],"vehicles":[{"make":"BUICK","model":"LACROSSE","year_from":2012,"year_to":2016,"match":"exact","vehicle_ids":["2012_buick_lacrosse","2013_buick_lacrosse","2014_buick_lacrosse","2015_buick_lacrosse","2016_buick_lacrosse"]},{"make":"BUICK","model":"REGAL","year_from":2012,"year_to":2016,"match":"exact","vehicle_ids":["2012_buick_regal","2013_buick_regal","2014_buick_regal","2015_buick_regal","2016_buick_regal"]},{"make":"CHEVROLET","model":"IMPALA","year_from":2014,"year_to":2014,"match":"exact","vehicle_ids":["2014_chevrolet_impala"]},{"make":"CHEVROLET","model":"MALIBU","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_chevrolet_malibu","2014_chevrolet_malibu"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
