- Use Autel Chrysler 12+8diagnostic cable on 2018 Dodge Challenger
It’s behind the radio, so we have to pull this, this is a 2018 Dodge Challenger way to pull this trim piece off. Let the radio hang and then if you come up here, the 12+8 diagnostic cable goes into this black box down here, if you have to reach in and push to release and slide them out and then hook up your 12+8 diagnostic cable.

So it took us a while to find it, it wasn’t even obvious once we got the radio out. I guess they put him in the kick panel I started there no luck. I was able to scan the codes through the OBD2 connection but I’m unable to clear them this cable right here. This box is what lets you hook up to clear the codes.
- Use Autel Chrysler 12+8 diagnostic cable on 2018 Dodge Durangowith Autel MS906TS
2018 Dodge Durango and Autel MS906TS, this is one of Chryslers that requires Autel Chrysler 12+8 cable which is not early as easy as the OBD2, so on this model in the Autel it drew a circle here I remove this trim panel just one clip nice and easy. These are your clips really tight to pull out, the release is on the back side so towards the driver’s of the car, they pull the release and then I put a pick to work them loose, then they come out, there are no labels or anything that show you that’s the 12+8 diagnostic cable, but that is definitely it and that’s what we had to do to get the pre and post scan done. So just wanted to share. It took me a little while to look around and see it. So I figured I could help you out a little bit.
