[American Customs]

Heey.

I bought a ram 1500 year 2020 with the 5.7l Hemi Etorque.

The following Problem right know is that it won't read the key and it dosen't make anything. The only thing is that on the Panel Cluster show me 2 messages. I also already connect a obd scanner to the ram and it won't read the vehicle.
i checket every Fuse.

any idea what it could be ??

Did you check the battery?

Check the RF hub as well. Any dampness in your rear headliner or behind the rear seat?

Pretty sure the RF hubs need to be programmed for them to work.

The Bus is down so it could be anything from a poor/corroded connection to a bad module.
I suggest you subscribe to one of the online "shop manuals" and go from there.

Could be anything on the can bus taking it down. Blind spot sensor or wiring to are an issue that has showed up before.

Did you make sure the battery you put in was all the way charged? I’ve had the no bus issue before but it was intermittent

Yup. Alfaobd and OBD Link MX+ comes to mind.
But first he needs to get the Bus back up and talking.

Yup. I have Jscan

I should perhaps try the Jscan.
It has taken me a considerable time just to get somewhat familiar with the Alfaobd.

You need to get the bus up and running first.

Maybe you have a bad ground

Did you bypass the security module?
