Need some help!!
Asked by Jesus Dec 01, 2017 at 01:44 AM about the 2008 Dodge Charger RWD
Question type: Maintenance & Repair
I have a 2008 Dodge Charger Daytona R/T, it got
flooded during hurricane Harvey, I took it to one of
my dads techs, but he hasn’t found diddly squat, I
was wondering if any one has any information on
how to get my car up and running again, it’s no
crank. No start, it says “no bus” on dash, and the
key fob does nothing when I first try to do anything
with it, I really need my car for school and for VA
appointments can someone point me I. The right
direction? Thank you!

If computer modules are fried it's going to get real expensive to fix. Flood damaged cars may look okay but they can be a nightmare to fix. Get ahold of good wiring diagrams that show all modules, you can try the free ones at Autozone's web site, or find manuals at a library, or buy an online subscription to Chiltons or Haynes (those come with way more pics than printed ones). Open up cases or boxes they're in and make sure no water is lingering in there, and reseat all harness connectors, get some dielectric grease in there. Computer diagnostics are probably going to be in order, any replaced module is going to need reprogramming. Corrosion is going to be another factor, most of those connectors or leads will corrode after exposure to water. I'll be honest with you, it may be a lost cause, one that will cost more to fix than the car is worth. It's also tough to sell a flood-damaged car, if you decide to cut your losses, part the car out to recoup costs.

Here's something to try: Do you have a second fob? If so, try it. I have seen the "NO BUS" message come up before and it was simply the fob going bad. If you do not have a second one, you may be able to get one programmed for the car and try it out. It could be electrical issues, and if so as mentioned above it's likely not worth fixing. But I would definitely try the key trick first.
A key fob alone couldn't cause a "no bus" fault, that is caused by a bad instrument cluster and/or instrument cluster module.
