Yes the LED was a california spec deal as per the owners manual alot like my 400E does not have a CEL. I also agree with Cliffmac on the reason it is throwing a code, except also adjust your duty cycle after replacing the O2 sensor.

Also, to Arthur. I've made the tool, but when I plug in the terminals at the test box, the LED simply lights solid. I've wired it as the diagram states, assuming that the wire for the test terminal is just spliced in between the switch and the LED. Is this correct, or is the ground supposed to run THROUGH the test terminal? To elaborate: I have the + side of the LED running to battery pos, one end of the switch going to ground (- on battery, or teminal 1 on test box), and in between, 1 splice that runs to the corresponding terminal on test box. Does this sound right? Thanks,

The test terminal has to be from the chart I sent you to.
Test the tool: On the bat , place the red on + and the odd on - Led should lite Red on + and Blk on - Led should lite ONLY when sw is ON

OK. I got it to work (I wasn't holding the button for several seconds first...). I have a code on terminal 6 (supplemental restraint, code is 8), but when I tried to get to the fuel diagnostics socket (2), it is empty. Just an empty hole, no post. 6 and 7 are the only terminals with posts in them (DOH!). I'm not seeing any wires laying around that were pushed out (or fell out, or whatever). Is there any other means of diagnosing? Or am I stuck with a halfassed diagnostics box? Thanks!

That chassis should have a CIS system socket at pin 3 [ not 2], unless it is Fed version.
See if there is a yellow Emmissions sticker under hood stating Cal Emmissions.

The only yellow sticker I see is on the airbox, but it is faded to where you can't read it. I did check socket three (not two, please read that as a typo), but it is just an empty hole.

Must be Fed version.
That site shows CIS codes from pin #3. Page 23.
