Hey all, new to the forum after being a long-time surfer.

I recently installed a built motor (had mine built), Killer Chiller, heads, cam, and transmission in my 2018 Hellcat Charger.

After installation and start-up I had lost all use of buttons, horn, paddle shifters, and cruise controls on my steering wheel, as well as use of the SRT Performance pages and gauge read-outs. I was told this is normal due to the battery being unhooked for extended time (about 2 weeks).

I have since drove the car about 5-600 miles in addition to some light dyno tuning and about 15-20 start ups with still no use of anything. I am especially trying to see/read the Intake Air Temps and SC Coolant Temps.

I am afraid to take it to the dealer because it is out of warranty (2018 with 33k miles and many modifications). I do have access to a Snap-On scan tool if that helps. I have also checked all fuses/relays that have to do with Steering Wheel Controls.

Any thoughts or advice would be appreciated. I am trying to see 200+MPH at the Texas Mile next week and want to get this thing straight!

You need a scanner capable of working with 18+ Dodge vehicles. Not all are, it requires a third party subscription.
Run a all Module scan. With my Apollo d8 that will tell me which modules are communicating on the buss and any codes set in each module.

Ive combed through everything probably 10x and had 3 other do the same incase I was missing something. I was concerned it may be a clockspring being I had that go out on a SRT Jeep, but thought it would be strange to go out with everything else going on. I thinking being mine is an 18+ my scan tool isn't picking anything up
