Some 2017 F-Series Super Duty pickups equipped with a rear auxiliary power point and built on or
before 20-Feb-2017 may remain running after the ignition is turned off. Prior to performing any
diagnostics, inspect the rear auxiliary power point for any aftermarket devices that can supply
voltage back into the vehicle. Items such as a battery jump pack can induce voltage that will
simulate key on status and prevent the powertrain control module (PCM) from shutting off the
engine. If no aftermarket devices can be located, refer to Workshop Manual (WSM), Section 211-05
for normal diagnostics.
