I have a bluetooth scan tool that I used on several other cars and have never had a problem.

I plug it in to my 03 cl-s 6mt and I only get the power on light. Occasionally I will get the other 2 lights that let you know its reading the computer for a brief second.

Anyone have ever have a similar issue?

 

test the unit by plugging it into a different car.
if it works for the different car, then it's the CL's fault.

 

Thanks for a quick response. I shall try this idea as well as a buddies hand held scan tool.

Last time I used it was when my car got totaled so hopefully it's just the tool.

If the tool does work though, and suggestions on what to check next?

 

i dont know How OBDII's operate, but have been in use since 1996

 

O well, figured while it was slow at work I would check and see if there was some common issue or someone had a similar one. Found a few for the RL and TL here did not see much on the CL about it though.

Guess I'll see if my buddy with the hand-held scanner is around after work today.
