Trailer Turn Signal - TIPM
I just bought a 2006 Dodge Ram 3500, 5.9 Cummins. I purchased a brand new fifth wheel. For a few days, the trailer brake and turn signals worked properly. Then, the trailer right side brake/turn signal light quit working. I diagnosed the problem as coming from the truck, as did an RV repair place. All signals on the truck work properly.
I looked for a fuse to replace but low and behold, found none for trailer lights. Instead, I found a very expensive substitute for a fuse called a TIPM. I didn't know this truck had such a device.
I took the truck to a small town Dodge dealer who "flashed" the TIPM and says that it's bad and must be replaced. The "flashing" didn't correct the trailer right side brake/turn signal problem.
Is this correct? Must the TIPM be replaced if "flashing" it doesn't correct the problem?
It's amazing to me that a manufacturer who bills it's trucks as "Ram tough" and touts their towing ability could have engineered such a thing for trailer lights! I'm disappointed already in my new truck!
