Owners of 2015 - 2016 Corvette Z06 models may comment about a MIL on with a DIC message. Technicians may find DTC P2227 set in history, and the service procedure diagnostics do not repair the vehicle. An outdated calibration is causing false fails in certain vehicles.
In “rare” cases, some owners of 2014 Chevy Equinox vehicles equipped with a 3.6L engine may comment that the MIL is on, accompanied by poor performance and reduced power. Technicians may find DTC P0641 stored.
