Code read Procedure
1. Plug reader into OBDII port.
2. Turn key to ON position.
3. Turn reader on (this may have happened when you turned on the ignition, mine does)
4. Hit whatever key causes the reader to read
5. you can then look at what codes were detected
6. Clear codes if desired.
The light won't necessarily flash a certain way to indicate a code, so the only sure way to tell is to get a reader on it.
