hhhhhmmmmm[sm=smiley5.gif]I've never heard of something like this before. I guess there might be a short somewhere on OBD's motheboard, but I'm not an electronics technician so I don't know. Maybe you can use the OBD tool to track down your problem.

You may have a bad ECM ground- it's grounding itself through your scantool- which is grounded through the OBDII connector.
