04' 4-cylinder 5-spd manual 113,000 miles. Service Engine Soon (not
the wrench symbol) light on. Scanned for codes via OBDII hand-held
scanner and return results were "PASS" no codes found. Disconnected
the battery for 15+ minutes and the light went off. Next day light
came back on.......scanned the OBDII and still "PASS" no codes found.
Should there not be a stored Pxxxx code that illuminates the dash
