Jump the TEN and GND pins inside the little black Diagnostics box. The box is under the hood on the drivers side, it says Diagnostics right on it. Once you do that turn the key on and watch the Check Engine light, it'll blink out the codes. Here's a list with instructions that I took from a website:

ECU Error Codes

To cause the ECU to flash the error codes on the MIL, short the TEN and GND terminals on your diagnosis connector, with the ignition off. Then turn your key to the "on" position and count the flashes.

To clear the error codes, disconnect the negative battery cable for at least 20 seconds, and depress the brake pedal. Re-connect the battery cable.

In the "pattern" column, the "L" stands for a long flash, and the "S" stands for a short flash.
