If the fuel transfer fails, P-codes will set, and the fuel gage will default to ?E?, the low fuel warning will illuminate in the driver information center (DIC) and there will be 2 sets of 5 chimes upon initial warning. If the customer continues to operate the vehicle without refueling the front tank, the Check Engine Light will illuminate, and the vehicle may exhibit reduced power mode. The vehicle may also lose propulsion and may fail to re-start (dependent on fuel pressure). Dealers are to inspect and, if necessary, replace the rear fuel pump.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10163848-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10163848-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10163848","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"SILVERADO 4500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_silverado"]},{"make":"CHEVROLET","model":"SILVERADO 6500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_silverado"]},{"make":"CHEVROLET","model":"duplicate SILVERADO 5500","year_from":2019,"year_to":2019,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
