Self Test as in though the Odometer trick/display?
Aside from seeing what code is being thrown, you can try this.
Unplug the negative battery terminal, leave it for 10 minutes/or unplug the negative battery terminal and lay on the horn, brake to drain the remaining power for about a minute, reconnect. This will reset the ECU. If the car throws a CEL again after this, then I'd go and get the code.
