Four problems related to wiring have been reported for the 2006 Dodge Ram 2500. The most recently reported issues are listed below.
Driving in traffic at night and lost turn signals and brake lights on trailer almost caused rear end collision. Found problem was with the tipm or fuse box. The trailer wiring from the tipm has no fuse and is some sort of relay and can only be repaired by a dealer. Have found this to be a very common problem with other Dodge truck owners. Many different circumstances can cause this failure due to only a 15 amp limit before failure. Dealers say they can do a reflash for around $100. 00 and if that does not work the tipm must be replaced at a cost of $1000. 00 and this would be the case each and every time there was a 15 amp overload to this circuit. This is a serious safety issue as dealers or not open 24 hours or 7 days a week and also very expensive. This should be a simple fused circuit as it is with almost all vehicles and the repair could be made by simply replacing the blown 25 cent fuse found at all gas stations and convenience stores. I hope no one has been killed or injured over this same type issue.
Upon connecting a trailer with a wiring fault to the 2006 Dodge ram diesel 4x2 , the tipm on the truck cuts off the circuit. Testing indicates a minor fault with the trailer wiring, which allows trailer lights to operate on non-Dodge vehicles. According to the local Dodge dealer the tipm has failed and must be replaced. The Dodge ram does not have a fuse for trailer turn signal circuits nor any other means to allow for the consumer to address wiring faults on trailers, regardless the Dodge ram is designed to allow towing. This presents a considerable safety risk as the consumer has zero means to address faults with the Dodge tpim after normal business hours or in areas without a Dodge dealer. The high cost of the tpim also discourages the average consumer from maintaining proper and safe operation of the vehicle upon a simple trailer fault. A simple inexpensive fuse as on pre-2005 Dodge ram vehicles for trailer circuits will greatly improve safety as the consumer can address issues with the Dodge ram from induced by simple trailer wiring faults. I have contacted the Dodge dealer and Chrysler llc about the issue and neither provides information that there is a fix to the tipm that enables the consumer to address the safety issue induced by replacing the module with a new one. Dodge nor Chrysler llc provided any instructions or documentation on how to advert tipm failures and safety issue resulting from their product not sending power to trailer lights. . Read more...
Tipm issue when left turn signal is activated no response to wiring harness. Which also would not activate trailer brake light due to no input from left signal. I think this is a problem when other drivers can't see brake lights all due to a bad tipm. Was told the dealer will replace for $700. My opinion with so many 06 Dodge 3500 with same problem this should be recalled. Talked to other owners who have been to dealer and there is a wait for back order due to many others having same problem.
This is an on going issue with my 2006 Dodge Ram 2500 . When driving at night sometimes when you switch the headlight from low beam to high beam they will completely go out or one side will go out. Also sometimes when you turn on your left blinker your right blinker will come on. The dealer told me that this was from hauling trailers with bad wiring. I don't understand how a trailer that is not connected to my truck can effect the lights. My truck is no longer under warranty and there is no way for me to diagnose this problem. (you must have a Chrysler computer to see what the controller is doing) I thought there were laws to protect consumers from manufacturers of cars that prevented them from making control systems that consumers could not access.
