being you have no scanner you have no idea what code you have, so get it scanned. follow the code to repair it.

to reset the pcm un hook the battery for 30 minutes or over night. but the light will come back if you have not fixed anything.

30 minutes isn't necessary. 30 seconds will do it. Hell 10 seconds will do it, but as mentioned go get it read so you know what you are dealing with. You could also buy a cheap reader on amazon or eBay.
