($0A) Emission Related DTC with Permanent Status
This selection displays a record of any “permanent” codes. 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. Even though the MIL may have been 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 may and the
related system monitor runs successfully.

•
SAE J1850 VPW (Variable Pulse Width)
