Also: can the code readers at AutoZone and/or Advanced Auto Parts read the codes on Pcars? (I called, and got sort of equivocal responses, like "Uh, yeah, it should read that OK..")

It's OK to drive short distances? (Like to the shop?)

Literally any OBD II scanner should be able to see “death codes” (those that trigger flashing CEL’s); that said, many scanners may not be able to clear them, but that is a separate issue. The DME can self clear erroneous codes, so it may have simply been a fluke. I’m not aware of the ignition switch triggering a flashing code, but anything is possible with electronic gremlins…………
