4.4.10 Service $0A:
Emission Related DTC with Permanent Status
This option displays a record of any “permanent” codes on late-model vehicles if the vehicle
supports Service $0A. A permanent status DTC is one that was severe enough to illuminate the
MIL at some point, but the MIL may not be on at the present time.
Whether the MIL was switched off by clearing codes or because the setting conditions did not
repeat after a specified number of drive cycles, a record of the DTC is retained by the ECM.
Permanent status codes automatically clear after repairs have been made and the related system
monitor runs successfully.
