+1 on the harbor freight code reader. I got one and shoved it in the glove box. I think it should be required overland equipment. Having at least a vague idea of what the CEL is indicating is a big deal on the trail.

One of the biggest reasons I'm a huge proponent of getting factory service literature is with it and a basic code reader you can trouble shoot check engine lights. On my 05 Ford I was able to work through the diagnostic tree and fix a check engine light with the manual, a $50 code reader and a multi meter.
