I would suggest looking in on dieseltruckresource.com or

turbodieselregister.com or

cumminsforum.com for input from a all Dodge crowd that probably has a fix already.

Take a look at TSB 08-021-06 rev A for trailer grounding problems and raising TIPM trigger points amps from 75 to 100.

There are no fuses on a 2006 (and forward) Dodge Ram to protect left/right trailer turn signal fault.

PLEASE READ MY ENTIRE POST (import details further down) and let me preface by asking Dodge experts, is there an after market modification that can be made to protect the TIPM from a trailer wiring fault?

Dodge Ram trucks from 2006 forward, have eliminated circuits with regular ol' fuses for the trailer circuits; left trailer turn signal and right trailer turn signal. If there is a fault, then the software in the truck's TIPM (Totally Integrated Power Module) shuts down that circuit. There is a counter within the software that allows only so many resets after a certain number of faults, then the module must be replaced (dealer item only). Note that the trucks turn signals work fine when the TIPM cuts off the trailer effected circuit(s).

There are NO fuses for the trailer turn signal circuits but there are fuses for the power seats, computers, stereo, etc ....WHAT THE HECK!?!? Dodge Trucks are designed to pull trailers and have trailer lights connected, but this is only controlled by the TIPM; it's insane. It's worse, read on....

Are you ready for this? A failed TIPM for a late model (2006 forward) Dodge Ram is $711 plus $200 labor. Extremely frustrating considering a simple fuse on the trailer circuit is inexpensive and effective.

Now to add insult to injury. In my particular instance on my 2006 Dodge Ram Diesel 2500, the TIPM faulted not because of a short to ground, but a short between the trailers left turn signal and the marker / running lights; no short to ground whatsoever. This type of fault will not make a fuse blow because there is not a short to ground.

Any Dodge experts, PLEASE post details on a work-around / fix to protect the TIPM against a positive to positive fault as I described ...my local Dodge dealer and Chrysler Customer Care cannot answer my question and offer zero assurance that a new TIPM can protect against such faults without require being replaced again and again (at $911 total cost).

Advice is appreciated.

Foot note: I attached the trailer to other non-Dodge Chrysler vehicles. The lights work, granted incorrectly, but no fuses are effected and the vehicles lights work fine.
