96 318ti No reading the obd2 scanner
 

Hey yall, hope the new year is treating everyone good!!! Ive been traveling and now back in the area. My 96 318ti has been great since the radiator and cooling repairs but Ive had a check engine light come and go. No visible or physical signs so I didnt think anything of it. Now the lights been on for a bit and wont go away, so I tried to use a acetron cp9135 obd2 scanner and it wont interface with the car! All my electronics work, so I'm stumped! Gonna try and pull the negative battery cable and see what happens. Any advice would be great guys!

You are connecting it to below the dash?
You do have the diagnostic cap under the hood secure?

Yes. An I will have to look under my hood tomorrow when there is light so I can see the location of the diagnostic cap to ensure it is secure.

Cap is secure and double checked for placement.

My OBD-II -> BT scanner isn't working but sometime ago I noticed I bent one of the pins in the plug.

Check all you pins in the scanner.
Other than that, IDK. Sorry.

:frown: ok. What about doing the reset like this?

That's not going to clear a CEL.
That will only reset the oil and/or inspection light.
