There are 2 diagnostic ports on this car, looks like this:
The round one is under the dash and the square one is under the hood on top of the engine toward the passenger side.
If you want to clear codes here take 2 wires and insert one into terminal Tc and the other into terminal AB in either port, there is a full map/label on each cover to show you the terminal locations.
Now turn the key to ON (not start just on). Then:
Starting with the Tc terminal, apply body ground alternately
to terminal Tc and terminal AB twice each in cycles of 1.0 +
0.5 seconds. (Confirm that body grounds is absolute.) Finally,
keep applying body ground to terminal Tc.
HINT: When alternately grounding the terminals Tc and AB,
release ground from one terminal and immediately apply it to
the other terminal. This action must be done within the time
limits shown below. If you are not within the time limits, repeat
the procedure until you clear the codes.
Do note that the codes and light may have come on because of a weak batery so this should be tested.
