Hi, I'm a new member. I have a 1998 dodge sst, I went to the inspection station to get my new sticker, and was told my obd won't communicate with their machine.
Does anyone have any ideas what I should look for first?
Thanks in advance for any help.

 

Clean the contacts on the connector would be my 1st step.

 

and check the IOD fuse.....

 

Thanks for the suggestions, I will try that.

 

Be sure to report back, also a common issue on OBD vehicles in general, is that the ground wire on the OBD port gets disconnected or worn, and can't give enough ground to the tool to accurately do its job, so keep that in mind if nothing else works. Good luck and keep us posted
