Dunno if this helps but…if you clear the codes before getting tested…
99 and older = allowed to have two incomplete tests (which may cause CEL) during inspection.
00 and above = allowed 1 incomplete test (which may cause CEL) during inspection.
You sure? Wouldn’t my ECU be classified as “Japanese”? My scan tool ($70 on EBay) scans it fine. Sometimes it says “Manufacturer specific code” but I can just google the few that come up like that.
