If you are looking simply to read out and clear fault codes you can use the
blink code technique described in the service manual. Scott Mockry has this
information along with some BTDT on his site at:
The SJM website shows a test light (LED US 1115 equivalent) for reading and
clearing ECU and transmission fault codes.
Otherwise, I think you have to have the fuse out, or disconnect the battery for
like 20 minutes to clear the codes.
The quickest way to clear codes by blink method is the "test mode" (see Scotts
I think Ed was referring to the Mixture Adaptation Information stored by the
ECU. This allows the ECU to "learn" about differences unique to a particular
car and the environment it's driven in. When this information is cleared it can
take a few miles of driving for the ECU to gather information from the O2 sensor
to restore meaningful data in the Fuel Trim Tables.
