In the engine bay. To the left there will be a black box that says diagnosis open it and jump terminal E1 and T . Turn the engine to on and check how many blinks the check engine light flashes. Get the number of blinks before and after the pause first set will be first number second set will be second numbet

Refer to the FAQ section for a thread about checking diagnostic/error codes. It has pictures and tells you what each code means.
