Quick OBD-II question, I think

[Marteney, Steven J.]

Vehicle was just serviced by dealer.  Fixed an "alleged" manifold leak,
various other things.  SES light did not come on before service.

  SES Flash Codes are NLA on OBD2. Necessary to use OBD2 Scan tool to
retrieve "Codes". See if the SES clears itself in 4 drive cycles, this is
part
of the OBD2 protocol "Monitors, especially if the vehicle appears to operate
correctly with no obvious driveability problems.
