This link is a place I found with leds with built in resistors, its on a post in exterior and lighting section too,
2x Car CAN-BUS Bulbs 36mm 2-SMD LED Festoon Light White - eBay (item 130429868726 end time Dec-08-10 00:32:42 PST)

if you didnt put can-bus bulbs in the leds your computer is having a field day registering all the lights thst it thinks are out. I believe your HIDS are ok since you put error code in them. I searched alot on LEDs and believe me, the easiest way to go is with the company in the link (factorykiss) yes its chinese but what isnt nowadays.

Try putting your normal bulbs back and see if the HIDs are causing the problem
